This force is centripetal force. it is the force that will hold the rider in the circular path and prevent him from skidding off. It is equal to the friction between the tyres and the road if no banking has been done on the road at the corner.
The force is applied to the accelerating object that has a constant mass. Option A is correct.
<h3>
What does Newton's second law of motion state?</h3>
The force applied to the object is the product of its mass and acceleration.

Where,
- force
- mass
- acceleration
From the equation, the force and the acceleration are in a proportional relation. The mass is not changing as given in the question.
Therefore, the force is applied to the accelerating object that has a constant mass.

When you shine a lite through a prism is reflects out light through all of the edges and causes light separation. Or just simply shine a laser through the edge of a sideways piece of glass.

Answer:
The lenses with different focal length are four.
Explanation:
Given that,
Radius of curvature R₁= 4
Radius of curvature R₂ = 8
We know ,
Refractive index of glass = 1.6
When, R₁= 4, R₂ = 8
We need to calculate the focal length of the lens
Using formula of focal length

Put the value into the formula



When , R₁= -4, R₂ = 8
Put the value into the formula



When , R₁= 4, R₂ = -8
Put the value into the formula



When , R₁= -4, R₂ = -8
Put the value into the formula



Hence, The lenses with different focal length are four.
Answer:
Yes, It is true.
The acceleration due to gravity is caused by field force.
