Primary and secondary succession comic strip using succession interactive

Answer:

170m

Explanation:

\(v_{f}=v_{i}+at\)

\(v_{f}=2+3\cdot10\)

\(v_{f}=32\ \frac{m}{s}\)

The final velocity is 32 meters per second

\(v_{f}^{2}=v_{i}^{2}+2ad\)

\(d=\frac{\left(v_{f}^{2}-v_{i}^{2}\right)}{2a}\)

\(d=170m\)

Therefore, the total distance travelled is 170m

Responder:

Explicación:

Las fuerzas que actúan paralelas al plano son la fuerza de movimiento y la fuerza de fricción.

La fuerza de movimiento Fm = Wsinθ y la fuerza de fricción Ff = nR donde;

W es el peso del objeto = mg = 30.0 * 10

W = 300N

θ es el ángulo de inclinación = 28 °

n es el coeficiente de fricción = 0,20

R es la reacción normal = Wcosθ

La fuerza paralela al plano que se debe ejercer sobre el bloque para que se eleve con rapidez constante será la suma de la fuerza de movimiento y la fuerza frictioal (son las dos fuerzas que empujarán el cuerpo hacia arriba del plano)

Fuerza total requerida = Fm + Ff

Fuerza total requerida = Wsinθ + n (Wcosθ)

Fuerza total requerida = 300sin28 ° + 0.2 (300cos28 °)

Fuerza total requerida = 140,84 + 52,98

Fuerza total requerida = 229.17N

Por tanto, la fuerza paralela al plano que se debe ejercer sobre el bloque para que se eleve con rapidez constante es aproximadamente 229,17 N

(a) The support of K can be given by {0, 1, 2, 3, 4}.

(b) The set of events in which the aircraft is functioning can be given as follows: {K ≥ 1}, which means the aircraft is functioning if and only if at least one of its engines is functioning properly.

(c) Let's assume that the probability of each engine functioning properly is given by p. So, the probability of any particular engine malfunctioning or not functioning properly is (1 - p).

Since the aircraft is functioning if and only if at least one of its engines is functioning properly, the probability of system reliability can be calculated using the following formula:

P(K ≥ 1) = 1 - P(K = 0)

Since each engine functions independently of each other, the probability of each engine malfunctioning can be multiplied together. Thus, we have:

P(K = 0) = (1 - p)^4

Then,

P(K ≥ 1) = 1 - P(K = 0)

= 1 - (1 - p)^4

Therefore, the probability of the aircraft functioning, which represents system reliability, is given by 1 - (1 - p)^4.

Explanation:

The question is incomplete, the complete question is;

The net force determines how and if an object will?

A) make a balanced force

B) change its mass

C) move or accelerate

When unbalanced forces act on an  object, the object moves  or accelerates. The correct answer is option C: move or accelerate

Force is considered as a push or pull. Unbalanced forces refers to a system of forces acting in opposite direction and are not equal in magnitude.

Unbalanced forces cause an object to move or accelerate in the direction of the larger force.

Hence, The net or resultant force determines how and if an object will move or accelerate when under the action of unbalanced forces.

Answer:

B. What are the base units of electric current?

To find out that the electric current is a vector or scalar quantity, Tim should ask what is the symbol for electric current. Hence, option C is correct.

A physical quantity whose size is a complete description of it. Volume, density, speed, energy, mass, and time are a few examples of scalars. Other quantities, like as force and velocity, are referred to as vectors since they have both magnitude and direction.

Real numbers that are typically positive but not always characterize scalars.

In physics, a vector is a quantity with both magnitude and direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity. A vector does not have position, while having magnitude and direction. In other words, a vector's shape is unaltered if it is shifted parallel to itself as long as its length is unaltered.

Explanation:

The magnetic field of a straight current-carrying wire forms concentric circles (option E.) around the wire, with the wire passing through the center.

The correct answer is option E. The magnetic field of a straight current-carrying wire is around the wire. Here's a step-by-step explanation:

1. When an electric current flows through a wire, a magnetic field is generated around the wire.

2. According to Ampere's right-hand rule, if you point your right thumb in the direction of the current flow, your curled fingers will represent the direction of the magnetic field lines.

3. The magnetic field forms concentric circles around the wire, with the wire passing through the center of these circles.

4. The strength of the magnetic field decreases with increasing distance from the wire.

5. The direction of the magnetic field is given by the right-hand rule. If you wrap your right hand around the wire with your thumb pointing in the direction of the current, your fingers will curl in the direction of the magnetic field lines.

6. This magnetic field around the wire is responsible for various phenomena, such as the attraction or repulsion between magnets and the wire, or the deflection of a compass needle when brought near the wire.

A hammer thrower accelerates the hammer from rest in four complete rotations (revolutions) and releases it with a speed of 26.5 m/s, then the angular acceleration is \(\alpha = (0 - 26.5 / 1.20) / [(4 \times 2\pi \times 1.20) / 26.5]\)

To solve this problem, we'll use the following equations:

(a) Angular acceleration (α) can be calculated using the formula:

\(\alpha = (\omega_f - \omega_i) / t\)

where

\(\omega_f\) is the final angular velocity,

\(\omega_i\) is the initial angular velocity, and

t is the time taken to accelerate.

\(\omega_f = 0\) (since the hammer is released)

\(t = (4 \times 2\pi \times 1.20) / 26.5\)

\(\alpha = (0 - 26.5 / 1.20) / [(4 \times 2\pi \times 1.20) / 26.5]\)

(b) Tangential acceleration \((a_t)\) is given by:

\(a_t = r \times \alpha\)

where

r is the radius of the circular path.

(c) Centripetal acceleration \((a_c)\) is given by:

\(a_c = r \times \omega^2\)

where

\(\omega\) is the angular velocity.

(d) Net force \((F_{net})\) is given by:

\(F_{net} = m \times a_t\)

where

m is the mass of the hammer.

(e) The angle \((\theta)\) can be calculated using the formula:

\(\theta = arctan(a_c / a_t)\)

Let's calculate each part step by step:

Given:

First, let's find the initial angular velocity (ω_i). In one complete revolution, an object covers a distance equal to the circumference of the circular path, so:

Circumference = \(2\pi r\)

Since the hammer completes four full turns, the distance traveled is 4 times the circumference. This distance is also equal to the linear distance traveled, which is v multiplied by the time taken (t) to accelerate:

\(4 \times 2\pi r = v \times t\\t = (4 \times 2\pi r) / v\)

Next, we can find the initial angular velocity:

\(\omega_i = 2\pi n / t\)

Substituting the values:

\(\omega_i = 2\pi \times 4 / [(4 \times 2\pi \times 1.20) / 26.5]\\= 2\pi \times 4 \times 26.5 / (4 \times 2\pi \times 1.20)\\= 26.5 / 1.20\)

When the earth wire is connected to the metal case of the washing machine, it provides an alternative pathway for electric current to flow if there is a fault, such as if the live wire touches the metal case. The earth wire is connected to the ground, which has zero potential, so any current that flows through the earth wire will not harm a person who touches the metal case. This is because the person's body is also at zero potential (ground potential) and there will be no potential difference (voltage) across the person's body, which means no electric current will flow through the person's body. Therefore, connecting the earth wire to the metal case of the washing machine ensures that any electrical faults will be safely conducted away from the person, reducing the risk of electric shock or electrocution.

To find the t-values for the given areas and degrees of freedom, we can use the t-distribution table or a statistical calculator. Here are the answers:

(a) Finding the t-value for an area of 0.10 in the right tail with 25 degrees of freedom:

Using symmetry, we know that the area in the left tail is also 0.10. Therefore, we need to find the t-value that corresponds to an area of 0.10 in the left tail with 25 degrees of freedom.

Using a t-distribution table or a calculator, we find that the t-value for an area of 0.10 in the left tail with 25 degrees of freedom is approximately -1.711.

Since the t-distribution is symmetric, the t-value for an area of 0.10 in the right tail with 25 degrees of freedom is the negative of the t-value for an area of 0.10 in the left tail. Therefore, the t-value we are looking for is approximately 1.711.

(b) Finding the t-value for an area of 0.05 in the right tail with 30 degrees of freedom:

Similar to part (a), using symmetry, we can find the t-value for an area of 0.05 in the left tail with 30 degrees of freedom.

Using a t-distribution table or a calculator, we find that the t-value for an area of 0.05 in the left tail with 30 degrees of freedom is approximately -1.699.

Again, due to symmetry, the t-value for an area of 0.05 in the right tail with 30 degrees of freedom is the negative of the t-value for an area of 0.05 in the left tail. Therefore, the t-value we are looking for is approximately 1.699.

(c) Finding the t-value for an area of 0.01 in the left tail with 18 degrees of freedom:

To find the t-value for an area of 0.01 in the left tail with 18 degrees of freedom, we can directly use a t-distribution table or a calculator.

Using a t-distribution table or a calculator, we find that the t-value for an area of 0.01 in the left tail with 18 degrees of freedom is approximately -2.898.

Since we are looking for the t-value that corresponds to the area left of it, the t-value we are looking for is approximately -2.898.

To convert pressure from atm (atmospheres) to mm Hg (millimeters of mercury), you can use the conversion factor:

1 atm = 760 mm Hg

Pressure in mmHg = 1.86 atm * 760 mmHg/atm

Pressure in mmHg = 1413.6 mmHg

Given that the pressure of the aerosol can is 1.86 atm, we can multiply this value by the conversion factor to find the equivalent pressure in mm Hg:

1.86 atm * 760 mm Hg / 1 atm = 1413.6 mm Hg

Therefore, the pressure of the aerosol can is approximately 1413.6 mm Hg when expressed in units of mm Hg.
