Answer:When a sphere rolls down an inclined plane without slipping, its linear acceleration at the bottom can be calculated using the following formula:
a = g * sin(theta)
where "a" is the linear acceleration, "g" is the acceleration due to gravity (approximately 9.8 m/s^2), and "theta" is the angle of inclination of the plane.
Let's break down the formula step by step:
1. First, we need to determine the component of the gravitational force that acts parallel to the inclined plane. This component is given by g * sin(theta), where "g" is the acceleration due to gravity and "theta" is the angle of inclination.
2. Since the sphere is rolling without slipping, the frictional force between the sphere and the inclined plane is responsible for its linear acceleration. This frictional force is equal to the component of the gravitational force parallel to the plane.
3. Therefore, the linear acceleration of the sphere as it reaches the bottom of the inclined plane is equal to the component of the gravitational force parallel to the plane, which is g * sin(theta).
For example, if the angle of inclination, theta, is 30 degrees, the linear acceleration of the sphere at the bottom of the inclined plane would be:
a = g * sin(30) = 9.8 m/s^2 * 0.5 = 4.9 m/s^2
So, the linear acceleration of the sphere as it reaches the bottom of the inclined plane would be 4.9 m/s^2 when the angle of inclination is 30 degrees.

Answer:
Option 3) Constructive And destructive interference of light waves
Explanation:
When the light is incident on a soap bubble of certain thickness it constructively interferes for wavefronts which are in phase to produce white light and when the wavefronts are out of phase, they undergo destructive interference to produce a series of colors. Thus, interference is the reason.
Answer:
The average force between the ball and bat during contact is 1131N.
Explanation:
The average force can be found employing Newton's second law:
(1)
Where F is the force, m is the mass and a is the acceleration.
The acceleration can be determined employing the equations for a Uniformly Accelerated Rectilinear Motion:
(2)
Where is the final velocity, is the initial velocity and t is the time.
Then, a will be isolated from equation 2:
(3)
Replacing equation (3) in equation (1) it is gotten:
But , therefore:
So, the average force between the ball and bat during contact is 1131N.
Answer:
The answer is B.
Explanation:
Given that the current (Ampere) in a series circuit is same so we can ignore it. We can assume that the total voltage is 60V and all the 3 resistance are different, 20Ω, 40Ω and 60Ω. So first, we have to find the total resistance by adding :
Total resistance = 20Ω + 40Ω + 60Ω
=120Ω
Next, we have to find out that 1Ω is equal to how many voltage by dividing :
120Ω = 60V
1Ω = 60V ÷ 120
1Ω=0.5V
Lastly, we have to calculate the voltage at R1 so we have to multiply by 20 (R1) :
1Ω = 0.5V
20Ω = 0.5V × 20
20Ω = 10V
