You want to prove the law of conservation of energy to a friend. for your demonstration you show that you can use a block and pulley machine to lift 100n with only 20n of input force. what would you say to your friend to explain how is this possible?

What type of light does this light bulb produce most (i.e. at what wavelength does the spectrum have maximum intensity)?

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

Answer fast for how does the force exerted by two magnets change as the magnets are moved farther apart? the magnetic force increases. the magnetic force decreases. the magnetic force stays the same.
