Imagine you are making an animation of a roller coaster with a pie chart representing the total amount of potential and kinetic energy in the system. What are the cars doing as the section representing kinetic energy increases in size?

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

we need to know the time interval during which the force acts. impulse of force = momentum change

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
