What happens to the period of a pendulum if the frequency is halved?

Answer:

ax = 1.23 m/s²

ay = -6.32 m/s²

Explanation:

The acceleration is equal to the change in velocity over time. So, the acceleration of in the x-component is equal to

Where vfx is the final velocity on the x-direction which is equal to 0 m/s because at the end the velocity is in the y-axis. vix is the initial velocity which is -2.70 m/s and t is the time, so t = 2.20s.

Replacing the values, we get:

In the same way, we can calculate the y-component of the acceleration as

Replacing vfy = -13.9 m/s and viy = 0 m/s, we get:

Therefore, the answer is

ax = 1.23 m/s²

ay = -6.32 m/s²

Answer:

x=L/2  y=0 and the charge q3 is ¼ of the charge q

Explanation:

For this exercise we will use Coulomb's law.

         F₁₂ = k q₁ q₂ / r₁₂²

From this expression we see that like charges repel and charges of different signs attract.

Let's apply this expression to our case, they indicate that the two charges are of equal magnitude and sign, therefore the force is repulsive, so that it is in equilibrium with a third charge (q₃) this must be of the opposite sign and be between the two charge (q)

let's apply Newton's second law to one of the charges, for example the one on the left

         -F₁₂ + F₁₃ = 0

           F₁₂ = F₁₃

          k q₁ q₂ / r₁₂² = k q₁ q₃ / r₁₃²

          q₂ / r₁₂² = q₃ / r₁₃²

          q₃ = q₂ (r₁₃ / r₁₂)²

The problem indicates the charge q₁ = q₂ = 4 q and the distance between them is r₁₂ = L = 9 cm = 0.09 m, we substitute

          q₃ = 4q (r₁₃ / L)²

Let's analyze the situation a bit that the charge 1 and 2 are in equilibrium with a single charge 3 this must be symmetrical between the two charge (the same force), therefore its position on the x axis must be r₁₃ = L/2 and how it is on the y axis = 0

let's substitute

           q₃ = 4q (L / 2L)²

            q₃ = 4q 1/4

            q₃ = q

the charge q3 is ¼ of the charge q

From the calculation, it is clear that the velocity of the electron is obtained as a value of 4.2 * 10^8 m/s.

The electric potential refers to the work that could be done when we bring a unit positive charge from infinity to a particular point on the electric filed. In this case, we are told that the;

field strength = 2.5 × 10^5 Vm-1

Distance apart = 2.0 cm  or 0.02 m

We could the obtain the electric potential as; field strength * Distance apart

=  2.5 × 10^5 Vm-1 *  0.02 m

= 5 * 10^3 V

We now have that;

ev = 1/2mve^2

e = unit of electronic charge

v = voltage

m = mass of the electron

ve= velocity of the electron

ve= √2ev/m

ve = √2 * 1.6 × 10^-19 * 5 * 10^3/9.1 × 10^-31

Plate boundaries represent the parts of the Earth's crust where plates come in contact with one another. There are three types of plate boundaries based on the movement and interaction of the plates involved. These are: Divergent Plate Boundaries, Convergent Plate Boundaries, and Transform Plate Boundaries.

Divergent Plate Boundaries
At divergent plate boundaries, two plates move away from each other as magma rises to the surface and creates new crustal material. Examples of divergent plate boundaries include the Mid-Atlantic Ridge, the East Pacific Rise, and the African Rift Valley.

Convergent Plate Boundaries
At convergent plate boundaries, two plates move toward each other and eventually collide. Depending on the type of plate involved, different types of interactions can occur. The three types of convergent plate boundaries are oceanic-continental, oceanic-oceanic, and continental-continental. An example of oceanic-continental convergence is the Pacific Northwest region of the United States. An example of oceanic-oceanic convergence is the Japanese Islands, and an example of continental-continental convergence is the Himalayas.

Transform Plate Boundaries
At transform plate boundaries, two plates move past each other in a horizontal direction. These boundaries are characterized by faults and earthquakes, such as the San Andreas Fault in California.

To create an illustration that represents each type of plate movement, you can draw a diagram that shows the direction of plate movement, the type of boundary, and any notable geological features associated with that type of boundary.

For example, a divergent plate boundary illustration could include a depiction of magma rising to the surface and creating new crustal material, while a transform plate boundary illustration could include a fault line and a depiction of the earthquakes that occur along that boundary.

One of the main benefits of informational interviewing is that it allows the person conducting the interviews to gain insights and information about a particular career or industry.

Answer:

1. Initial vertical velocity its 0m/s

2. 2.47 seconds

3. 10.12 m/s

4.10.12 m/s

Explanation:

Remember that we have here two parts of a problem, first we know that the ball made a free fall of 30 meters, since the ball was hit horizontally and doesn't state otherwise the vertical velocity is 0. To calculate the time we just use 30 m as our Height and use the formula for vertical distance on free fall:

\(H=\frac{g*t^{2} }{2} \\\)

Now we just solve for time:

\(t=\sqrt{\frac{2H}{g} }\)

With this we just insert the values we know:

\(t=\sqrt{\frac{2H}{g} }\\t=\sqrt{\frac{2*30}{9.81} }\\t=2.47\)

Now we know that the ball was 2.47 seconds in the air, so the ball hti the ground at the second 2.47.

To calculate the velocity of the ball we just need to divide the horizontal distance covered by the time it spent on air:

\(v=\frac{d}{t} \\v=\frac{25}{2.47} \\v=10.12\)

The final and initial horizontal velocity of the ball would be the same since nothing states otherwise, of course the hitting of the ground would decrease its velocity but since nothing is said in the problem it is not considered.

1. The initial-vertical velocity of the golf ball is equal to zero because the ball would start its motion from a stationary position (at rest).

2. The time it took the golf ball to hit the ground is 2.47 seconds.

3. The initial-horizontal velocity of the golf ball is 10.12 m/s.

4. The final-horizontal velocity of the golf ball is 10.12 m/s.

Given the following data:

1. The initial-vertical velocity of the golf ball is equal to zero because the ball would start its motion from a stationary position (at rest).

2. To determine the time it took the golf ball to hit the ground:

At maximum height, time is given by the formula:

\(Time = \sqrt{\frac{2H}{g} }\)

Where:

Substituting the given parameters into the formula, we have;

\(Time = \sqrt{\frac{2\times 30}{9.8} }\\\\Time = \sqrt{\frac{60}{9.8} }\\\\Time =\sqrt{6.12}\)

Time = 2.47 seconds.

3. To determine the initial-horizontal velocity of the golf ball:

\(Horizontal\;velocity = \frac{Horizontal\;distance}{Time} \\\\Horizontal\;velocity = \frac{25}{2.47}\)

Initial horizontal velocity = 10.12 m/s.

4. To determine the final-horizontal velocity of the golf ball:

The initial-horizontal velocity and final-horizontal velocity of the golf ball would be the same.

The statement" The direction of the force on the charge placed in the electric field is upward" is false because the direction of the force on a negative charge (-6 C) placed in an upward-directed uniform electric field of magnitude 24 N/C would be downward.

The direction of the force on a charged particle placed in an electric field is determined by the charge of the particle and the direction of the electric field. In this case, a charge of -6 C is placed in an electric field directed upward with a magnitude of 24 N/C.

The force on a charged particle in an electric field can be calculated using the formula:

F = q * E

Where F is the force, q is the charge of the particle, and E is the electric field.

Since the charge q in this case is negative (-6 C) and the electric field E is directed upward, we can substitute the values into the formula:

F = (-6 C) * (24 N/C)

F = -144 N

The negative sign in the force value indicates that the force is in the opposite direction to the electric field. Therefore, the force on the charge placed in the electric field is downward, not upward.

The force on a negative charge is always opposite to the direction of the electric field. This is because negative charges experience an attractive force towards positive charges, and electric fields are directed from positive charges to negative charges.

Therefore, the statement "The direction of the force on the charge placed in the electric field is upward." is false.

Answer:

Explanation:

The acceleration of an electron in an electric field is given by the equation:

a = qE/m

where a is the acceleration, q is the charge of the electron, E is the electric field, and m is the mass of the electron.

Given that the acceleration of the electron is 4.3 m/s^2, and the mass of the electron is 9.11 × 10^-31 kg, and the charge of the electron is -1.6 × 10^-19 C, we can solve for the electric field E:

E = ma/q

E = (4.3 m/s^2) × (9.11 × 10^-31 kg) / (-1.6 × 10^-19 C)

E = -2.44 × 10^4 N/C

The negative sign indicates that the direction of the electric field is opposite to the direction of the electron's motion. Therefore, the magnitude of the electric field required to accelerate an electron with an acceleration of 4.3 m/s^2 is 2.44 × 10^4 N/C and the direction is opposite to the direction of motion of the electron.

In a material, the magnetic behavior depends on the alignment of magnetic moments of the atoms. Magnetic moments are generated by the motion of the electrons in the atoms. When the magnetic moments of atoms in a material are aligned in a specific pattern, it creates a magnetic field which results in the material being magnetic.

In many materials, the magnetic behavior arises due to the alignment of magnetic domains, which are regions of atoms with magnetic moments aligned in the same direction. When many domains with aligned magnetic moments are present in a material, the material becomes magnetic.

The magnetic behavior of a material depends on the number of electrons and the arrangement of those electrons in the atoms. In particular, for an atom to have a magnetic moment, it must have unpaired electrons, meaning electrons that are not paired with another electron with the opposite spin. When these unpaired electrons in the atoms are aligned, they generate a magnetic moment. If all electrons are paired, there will not be a net magnetic moment, so the material will not be magnetic.

So, in summary, the magnetic behavior of a material is determined by the alignment of magnetic moments of atoms. When the magnetic moments of many atoms in a material align in the same direction, it creates a magnetic field, leading to a material being magnetic. This alignment is usually present in magnetic domains consisting of atoms with unpaired electrons.

Answer: 4 m/s

Explanation:

To solve this problem, we can use the principle of conservation of momentum, which states that the total momentum of a closed system remains constant before and after a collision.

Let's denote the initial velocity of the 2 kg ball as "v1i", the initial velocity of the 6 kg ball as "v2i", the final velocity of the 2 kg ball as "v1f", and the final velocity of the 6 kg ball as "v2f".

According to the principle of conservation of momentum, the total momentum before the collision is equal to the total momentum after the collision. Mathematically, this can be expressed as:

m1 * v1i + m2 * v2i = m1 * v1f + m2 * v2f

where m1 is the mass of the 2 kg ball, m2 is the mass of the 6 kg ball, v1i and v2i are the initial velocities, and v1f and v2f are the final velocities.

Given:

m1 = 2 kg

m2 = 6 kg

v1i = 12 m/s (initial velocity of the 2 kg ball)

v2i = 0 m/s (initial velocity of the 6 kg ball, as it is stationary)

v1f = 0 m/s (final velocity of the 2 kg ball, as it comes to rest)

Plugging in the given values into the conservation of momentum equation:

2 * 12 + 6 * 0 = 2 * 0 + 6 * v2f

24 = 6 * v2f

Dividing both sides by 6:

v2f = 24 / 6 = 4 m/s

So, the velocity of the 6 kg ball after the collision is 4 m/s.

Answer:

Horizontal component: \(F_x = 58\ N\)

Vertical component: \(F_y = 33.5\ N\)

Explanation:

To find the horizontal and vertical components of the force, we just need to multiply the magnitude of the force by the cosine and sine of the angle with the horizontal, respectively.

Therefore, for the horizontal component, we have:

\(F_x = F * cos(angle)\)

\(F_x = 67 * cos(30)\)

\(F_x = 58\ N\)

For the vertical component, we have:

\(F_y = F * sin(angle)\)

\(F_y = 67 * sin(30)\)

\(F_y = 33.5\ N\)

So the horizontal component of the tension force is 58 N and the vertical component is 33.5 N.

The force needed to accelerate a mass of 40 kg from velocity v₁ = (4î - 5) + 3k)m/s to v = (8î + 3) - 5k)m/s in 10 seconds is 12.4 N.

Start by calculating the change in velocity (Δv) experienced by the object. This can be done by subtracting the initial velocity v₁ from the final velocity v.

Δv = v - v₁ = ((8î + 3) - 5k) - ((4î - 5) + 3k)

= 8î + 3 - 5k - 4î + 5 - 3k

= 4î - 8k + 8

Next, calculate the acceleration (a) using the formula:

a = Δv / t

where t is the time interval, given as 10 seconds.

a = (4î - 8k + 8) / 10

= (0.4î - 0.8k + 0.8) m/s²

The force (F) required to accelerate the object can be found using Newton's second law:

F = m * a

where m is the mass, given as 40 kg.

F = (40 kg) * (0.4î - 0.8k + 0.8) m/s²

= (16î - 32k + 32) N

Simplify the expression to obtain the final answer:

F = 16î - 32k + 32 N

≈ 12.4 N

Therefore, the force needed to accelerate a mass of 40 kg from velocity v₁ = (4î - 5) + 3k)m/s to v = (8î + 3) - 5k)m/s in 10 seconds is approximately 12.4 N.
