Answer:
1.5min
Explanation:
To solve the problem it is necessary to take into account the concepts related to Period and Centripetal Acceleration.
By definition centripetal acceleration is given by
Where,
V = Tangencial velocity
r = radius
With our values we know that
Therefore solving to find V, we have:
For definition we know that the Time to complete are revolution is given by
Answer:
Explanation:
Potential Energy= Kinetic Energy
Let 
be the value of Kinetic Energy.
We know that
Make 
the subject of the formula to get speed at the bottom of the hill.
Answer:
So increasing the voltage increases the charge in direct proportion to the voltage. If the voltage exceeds the capacitors rated voltage, the capacitor may fail due to breakdown of the dielectric between the two plates that make up the capacitor.
Explanation:
A option.
The resultant force is 5N.So the box moves to right with constant acceleration.
