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:
Negative
Explanation:
If a negatively charged object is used to charge a neutral object by induction, then the neutral object will acquire a positive charge. And if a positively charged object is used to charge a neutral object by induction, then the neutral object will acquire a negative charge:
We have a neutral sphere
1) Electrons are attracted to the positive charge
2) Electrons enter the sphere from ground, attrated to the + charge in the sphere
3) The sphere has an excess of e- having entered from the ground
4) Electrons redistribute uniformly
When you are holding the ball it has potential energy and when you through it it will then have kinetic energy as it go's up then it will pause for a brief sec. and then that 's when it has the greatest potential energy and then when it falls back down is when it has the greatest kinetic energy. The mechanical energy would be when you through the ball.
Hope this helps:)
Here we would use the equation
When we sub in we would would write it as
you would the solve the equation for an answer of 5
