•a cable is suspended over a pulley. a 5.0 kg mass is attached to
one end of a cable and 10.0 kg mass is attached to the other end.
when the system is released, the 5 kg mass accelerates upward.
find the tension in the cable. ignore the friction, the mass of the
pulley and the mass of the cable.

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.

The amount of heat required to change liquid water to vapor at its boiling temperature is 2256 kj/kg. the amount of heat required to change liquid mercury to its vapor state at its boiling temperature is 295 kj/kg. one kg of each substance is currently at its boiling point. how will the amount of thermal energy required to change each substance from a liquid to a gas differ?
