As measure the tension at either end of the cable, as well as the horizontal distance between the weight and the person holding the free end of the cable.

\(T_A_B\), \(T_A_E\), and \(T_A_C\) Represent the tensions in cables AB, AE, and AC, respectively.

\(u_A_B = \frac{ (AB)}{||AB||}\)

\(u_A_E = \frac{ (AC)}{||AC||}\)

\(u_A_C = \frac{ (AC)}{||AC||}\)

Where ||AB||, ||AE||, and ||AC|| are the magnitudes of the vectors AB, AE, and AC, respectively.

The tension in cables AB, AE, and AC can then be stated as follows:

\(T_A_B=T_A_B\times u_A_B\)

\(T_A_E=T_A_E\times u_A_E\)

\(T_A_C=T_A_C\times u_A_C\)

Answer:

This question is incomplete, the options are:

A) The object absorbs most white light and refracts most green light.

B) The object refracts most white light and absorbs most green light.

C) More green light is absorbed while more red and blue light is reflected.

D) More green light is reflected while more red and blue light is absorbed.

The answer is D.

Explanation:

Light is an electromagnetic wave that contains different colours at different wavelength. The colour of light that is seen depends on the wavelength of light that is REFLECTED, while other wavelengths of light are ABSORBED. This feature is dependent on the properties of each object that received the sunlight.

For example, an object will appear GREEN because it has properties that enables it to REFLECT most of the GREEN LIGHT but absorbs most of the RED AND BLUE LIGHT in the sunlight passing through the object.

Answer:

D

Explanation:

More green light is reflected while more red and blue light is absorbed.

Given what we know, the light rays that you see on the surface of the mirror are at the same angle as the light rays that your friend sees.

This has to do with the way in which a mirror affects the light that hits it. A mirror will reflect light, but will do so at the same angle that the light reaches it. This means that if the light reaches the mirror at a 40-degree angle, it will be reflected in the opposite direction at a 40-degree angle.

Therefore, we can confirm that the light rays that you see on the surface of the mirror are at the same angle as the light rays that your friend sees.

The time taken to reach one crest is 0.5731 s. Then the time period of the wave is 1.146 s. The frequency is the inverse of the period that is 0.87 Hz.

The time period of a wave is the time required to complete one wave cycle. For a transverse wave the period of the wave is the time required to reach from one crest to the next crest of the wave.

Given that, time to reach one crest = 0.5731 s.

then the time for to the next crest from the equilibrium position is :

T = 0.5731 s× 2 = 1.146 s.

Frequency of a wave is the number of wave cycles per second. It is the inverse of time period of the wave.

Hence, frequency = 1/T

ν = 1/ 1.146 s = 0.87 Hz.

If a simple pendulum has a period of 2. 23 seconds and the value of acceleration due to gravity is given as 9.8ms^2. Then the length of the pendulum is 1.233 meters.

The period of a simple pendulum is given by the formula:

T = 2π√(L/g)

where T is the period, L is the length of the pendulum, and g is the acceleration due to gravity.

We are given that T = 2.23 seconds and g = 9.8 m/s^2. Therefore, we can solve for L:

2.23 = 2π√(L/9.8)
Squaring both sides, we get:
4.975 = 4π^2(L/9.8)
Multiplying both sides by 9.8, we get:
48.755 = 4π^2L
Dividing both sides by 4π^2, we get:

L = 1.233 meters (rounded to three decimal places)

Therefore, the length of the pendulum is 1.233 meters.

The value of the charge that experiences a force of 2.4 × 10–3 N in an electric field of 6.8 × 10–5 N/C is 3.5 x 101 c

The force (F) experienced by a charged particle in an electric field (E) is given by the equation:

F = qE

Where q is the charge of the particle.

In this problem, we are given the force (F) and the electric field (E), and we need to find the value of the charge (q).

Substituting the given values into the equation, we get:

2.4 × 10–3 N = q × 6.8 × 10–5 N/C

Solving for q, we get:

q = (2.4 × 10–3 N) / (6.8 × 10–5 N/C)

q = 3.529 × 10–2 C

Therefore, the value of the charge that experiences a force of 2.4 × 10–3 N in an electric field of 6.8 × 10–5 N/C is 3.529 × 10–2 C.

Answer:

A stronger force changes increases velocity more due to increased acceleration on the object if the mass is constant as compared to a weaker force.

Explanation:

Force affects how objects behave in terms of motion, direction, shape etc. When an object is in a state of rest, then force is applied, the object starts to move is a particular direction. Increase in the force applied will make the object to speed up which is to say the velocity will increase.

For example:

When a ball is kicked with a player with a force of 10 N the velocity of the ball is recorded to be 3 m/s. When the player is replaced with a kid the force on the ball is 2 N and its velocity is recorded to be 0.3 m/s.

Reasoning

Increased in force applied on an object increases its acceleration resulting to a higher velocity of the object.

F= m * a --------if  mass is constant , increased force will increase acceleration and speed up the object.

Answer:

6970 N

Explanation:

To calculate the average force exerted on the ball, we can use the impulse-momentum theorem, which states that the impulse on an object is equal to its change in momentum. In equation form:

Impulse = Δp

where Impulse is the force applied over a given time, and Δp is the change in momentum of the object.

We can calculate the momentum of the ball before the hit as:

p1 = m * v1

where m is the mass of the ball and v1 is its initial velocity (which we assume to be zero). Substituting the given values, we get:

p1 = (0.85 kg) * 0 m/s = 0 kg m/s

The momentum of the ball after the hit is:

p2 = m * v2

where v2 is the final velocity of the ball (82 m/s). Substituting the given values, we get:

p2 = (0.85 kg) * 82 m/s = 69.7 kg m/s

The change in momentum (Δp) is therefore:

Δp = p2 - p1 = 69.7 kg m/s - 0 kg m/s = 69.7 kg m/s

The impulse on the ball is equal to the change in momentum, so we have:

Impulse = Δp = 69.7 kg m/s

Finally, we can calculate the average force exerted on the ball using the formula:

Impulse = Force * time

Substituting the given values, we get:

69.7 kg m/s = Force * 0.01 s

Solving for Force, we get:

Force = 6970 N

Therefore, the average force exerted on the ball by the bat is 6970 Newtons.

When voiced speech sounds are produced, the airflow through the glottal opening is complex and periodic, which implies that the frequency spectra of voiced sounds contain harmonics that are integer multiples of the fundamental frequency. The fundamental frequency represents the pitch of the sound, and the harmonics contribute to the timbre or quality of the sound.

This is known as the harmonic series and gives voiced sounds their characteristic timbre. The amplitude of each harmonic decreases as the frequency increases, resulting in a spectrum that is dominated by the lower harmonics. The exact shape of the spectrum varies depending on the individual's vocal anatomy and the phoneme.

The new angular speed of the block is 9.72 rad/s.

To solve this problem, we can use the conservation of angular momentum.

The angular momentum of the block is given by L = Iω, where I is the moment of inertia and ω is the angular speed. Since the block is a point particle and is rotating in a circle, its moment of inertia is simply mR^2, where R is the radius of the circle.

Initially, the angular momentum of the block is L1 = mR1^2ω1, where R1 = 0.3 m and ω1 = 2.43 rad/s.

When the cord is pulled and the radius is reduced to 0.15 m, the new angular momentum of the block is L2 = mR2^2ω2, where R2 = 0.15 m and ω2 is the new angular speed we want to find.

Since angular momentum is conserved, we can set L1 = L2:

mR1^2ω1 = mR2^2ω2

Simplifying, we get:

R1^2ω1 = R2^2ω2

Substituting the given values, we have:

(0.3 m)^2(2.43 rad/s) = (0.15 m)^2ω2

Solving for ω2, we get:

ω2 = (0.3 m)^2(2.43 rad/s)/(0.15 m)^2 = 9.72 rad/s

Therefore, the new angular speed of the block is 9.72 rad/s.
