Answer:
Explanation:
For unbanked road the maximum friction force will provide centripetal force to the car.
So here we will have
Since we know that centripetal force here is due to friction force
now for two cars we will have
also we have
now by division of two equations
so we will have
Answer:
heat and power
Explanation:
is the simultaneous production of electricity and heat both of which are used
Answer:
Explanation:
Given
Potential Energy of a particle is given by
For minimum or maximum Potential Energy differentiate U(x) w.r.t x
putting
To know minimum value check
at x=-2
so at x=-2 potential energy is minimum
Answer:
Explanation:
Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
