Therefore, the angle between vectors `u` and `v` is 90°.

To find the angle between two vectors, we can use the formula:

`cos(θ) = (u . v) / (||u|| ||v||)`

Where u and v are vectors, `.` is the dot product of vectors and || || is the magnitude of a vector.θ is the angle between the two vectors.

In this problem, we need to find the angle between vectors `u` and `v`.

We have the following vector

s:u = (2, 3, 0) and v = (3, −2, 1)

Let's find the dot product of vectors `u` and `v`.u .

v = 2 × 3 + 3 × (−2) + 0 × 1

= 6 − 6 + 0

= 0

Let's now find the magnitudes of vectors `u` and `v`.||u|| = √(2² + 3² + 0²) = √(13) and

||v|| = √(3² + (−2)² + 1²)

= √(14)

Now, we can use the formula to find the angle between vectors `u` and `v`.cos(θ) = (u . v) / (||u|| ||v||)cos(θ)

= 0 / (√(13) × √(14))cos(θ)

= 0θ

= cos⁻¹(0)θ

= 90°

The angle between the vectors u = (2, 3, 0) and v = (3, −2, 1) is 90 degrees.

Explanation:

The earths rotation on its axis

Answer:

The quadratic function models the path of the rocket. When we substitute an x value, we can determine the height in feet of the rocket.

To determine the height it was launched from, we would look at the y-intercept. This represents the starting value, as time = 0 in this point (cannot have negative time).

To determine how far the rocket traveled, we would look at the positive x-intercept of the expression. At this point, height = 0, so we can see the distance from start to finish of the rocket.

To determine the greatest height achieve, we would look at the vertex of the parabola generated from the given function. Using (-b/a, f(-b/a)), we can determine the greatest height achieved.

Density = Mass / Volume

Denisty of Ethanol = 3.9 g / 5.0 mL

                               = 0.78 g/mL

Density of Benzene = 44 g / 5.0 mL

                                 = 8.8 g/mL

∴ Benzene is Denser.

Explanation:

There are 5 kinematic equations, and 5 variables.

Each question will give you 3 variables and ask you to solve for a fourth.

To determine which equation to use, look at which variable is not included in the problem.

For example, if the question does not include time, then you need to use a kinematic equation that does not have t in it.  That would be:

v² = v₀² + 2aΔx

Or, if the question does not include the final velocity, then you need a kinematic equation that does not have v in it.  That would be:

Δx = v₀ t + ½ at²

Using average mass of earth, there are approximately \(1.495 \times 10^{50} $atoms$\) in Earth.

An object's mass and number of atoms are directly proportional to one another. The number of atoms in an object increases as its mass increases, and the opposite is also true.

You may determine an object's atomic composition by dividing its mass by the average mass of its constituent atoms. Since the average mass of the atoms in the earth is 40 u and its mass is \(5.98 x 10^{24} kg\), it is possible to calculate the number of atoms in the earth by dividing its mass by the average mass of its atoms.

We can determine the total number of atoms in an object using this approach.

The number of atoms in Earth can be calculated by dividing the total mass of Earth by the average mass of an atom.

Using the given information, we get:

\(5.98 \times 10^{24} kg / 40 u \\= 1.495 \times 10^{50} atoms.\)

Therefore, there are approximately \(1.495 \times 10^{50} $atoms$\) in Earth.

The property of a transverse wave that stays the same even as the wave's energy and other properties change is the wavelength.

The correct option to the given question is option a.

The wavelength is the distance between two successive points of the wave that are in phase. As the wave's energy and amplitude change, the distance between two successive points of the wave that are in phase remains the same.

This is because wavelength is determined by the frequency of the wave and the speed of propagation. The frequency of the wave is the number of cycles of the wave that occur in one second, while the speed of propagation is the rate at which the wave travels through a medium.

If the frequency of the wave and the speed of propagation remain the same, then the wavelength will also remain the same even as the wave's energy and other properties change. This property is known as the characteristic of the wave.The amplitude is the maximum displacement of a point on the wave from its rest position. The frequency is the number of cycles of the wave that occur in one second. The rest position is the position of the medium when it is not disturbed.

Hence, wavelength of a transverse wave remains same even as the wave's energy and other properties change.

The object would be moving at a constant velocity of 2 m/s.

A vector number called velocity is used to explain how quickly an object's position changes in relation to time. It is stated in terms of metres per second (m/s) or kilometers per hour (km/h), and is defined as the displacement (change in position) of an object divided by the time interval during which the displacement occurred.

The momentum (p) of an object is defined as the product of its mass (m) and velocity (v):

p = mv

We can rearrange this equation to solve for velocity:

v = p / m

Substituting the given values, we get:

v = 10 kg.m/s / 5 kg

Simplifying the expression, we get:

v = 2 m/s

Therefore, the object is moving at a constant velocity of 2 m/s.

The efficiency of moving the box is 60%.

Given in the question

Force exerted by peter = 500 N

Force due to friction on box = 200 N

Distance Traveled by box = 3 meters

Now work done by the force is given by

Work Done = (Magnitude of Force) × (Distance traveled)

Let us find work done by each force,

Work done by peter

Work Done = (Magnitude of Force) × (Distance traveled)

Put in the value, we get

Work Done =500 × 3

Work Done by peter = 1500 J

Similarly, Work done by friction

Work Done = (Magnitude of Force) × (Distance traveled)

Put in the value, we get

Work Done =200 × 3

Work Done by Friction = 600 J

As we know the work done by friction force is always negative,

Work Done by Friction = -600 J

So, net Work done = Work Done by peter + Work Done by Friction

net Work done = 1500 - 600

Net Work done = 900 J

Now Efficiency = (Net work done/work done by peter) × 100

Put in the values, we get

Efficiency = (900/1500) × 100

Efficiency = (3/5) × 100

Efficiency = 300/5

Efficiency = 60 %

So, the efficiency of moving the box is 60%.

\(\\ \bull\sf\dashrightarrow Acceleration=\dfrac{Force}{Mass}\)

\(\\ \bull\sf\dashrightarrow Acceleration=\dfrac{9.8}{4}\(

\(\\ \bull\sf\dashrightarrow Acceleration=2.45m/s^2\)

When a net force of 10 N applied on a 3 kg object, after it has moved 5 m, the velocity of the object is 5.77 m/s

When a force F applied on m kg mass, then according to the Newton 2nd law of motion, the object will acquire an acceleration:

a = F/m

From the problem,

F = 10 N

m = 3 kg

Hence, the acceleration is:

a = 10/3 m/s²

The relation between the velocity, distance, and acceleration is:

v² = u² + 2.a.s

Where:

v = final velocity

u = initial velocity

s = distance

Since the object is initially at rest, hence u = 0

Therefore,

v² =  2.a.s

v² =  2.10/3 . 5

v² =  100/3

Answer:

The energy an object has due to its motion is called kinetic energy

Explanation:

Factors Affecting Kinetic Energy: the kinetic energy of an object depends on both its speed and its mass.

Answer:

kinetic energy

Explanation:

In physics, the kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

The required amount of heat energy lost in a system when surroundings performed certain amount of work and when internal energy is increased is  calculated to be - 30 kJ.

Given that,

Work done on the system w = 75 kJ

Internal energy ΔU is increased by 45 kJ

Heat energy q lost or gained by the system = ?

From the first law of thermodynamics, mathematically, expression can be written as, ΔU = q + w

q = ΔU - w = 45 kJ - 75 kJ = - 30 kJ

The negative sign indicates that the heat energy is lost.

Thus, the amount of heat energy lost in the system is - 30 kJ.

Answer:

\(20\; {\rm m\cdot s^{-1}}\), assuming that friction is negligible.

Explanation:

If an object of mass \(m\) moves at a velocity of \(v\), the momentum \(p\) of this object would be \(p = m\, v\).

if friction is negligible, the sum of the momentum should be the same before and after the collision.

Before the collision:

In other words, the sum of momentum was \(40\; {\rm kg\cdot m\cdot s^{-1}}\) before the collision.

After the collision:

The sum of the momentum stays unchanged at \(40\; {\rm kg\cdot m\cdot s^{-1}}\). Subtract the momentum of the ice skater from the sum to find the momentum of the snowman:

\(40\; {\rm kg\cdot m\cdot s^{-1}} - 0\; {\rm kg\cdot m\cdot s^{-1}} = 40\; {\rm kg\cdot m\cdot s^{-1}}\).

Divide the momentum of the snowman by its mass to find its velocity:

\(\begin{aligned}\frac{40\; {\rm kg\cdot m\cdot s^{-1}}}{2\; {\rm kg}} = 20\; {\rm m\cdot s^{-1}}\end{aligned}\).

In other words, the collision of the snowman would be \(20\; {\rm m\cdot s^{-1}}\) after the collision.
