Thermometer. freezing point than mercury
Why does the bulb of a bicycle run with a dynamo
glow brightly when speed of bicycle is increased and
become dim when the speed is decreased?
Give reason.
​

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

the inner core.

good luck: )

klicker

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
