a figure skater is spinning slowly with arms outstretched. she brings her arms in close to her body and her moment of inertia decreases by 1/2. by what factor does her rotational kinetic energy change?

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

the closer the planet is to the sun, the larger the gravity

what is the actual question though?

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
