An atom of beryllium (m8.00 u) splits into two atoms of helium (m4.00 u) with the release of 92.2 kev of energy. suppose the beryllium atom moved in the positive x direction and had a kinetic energy of 37.1 kev. one of the helium atoms is found to be moving in the positive x direction. find the direction of motion of the second helium, and find the velocity of each of the two helium atoms. solve this problem in two different ways: by direct application of conservation of momentum and energy; and by applying the results if the original beryllium atom is at rest to a frame of reference moving with the original beryllium atom and then switching to the reference frame in which the beryllium is moving (a) by direct application of conservation of momentum and energy velocity of the first helium (magnitude) velocity of the second helium (magnitude) 1491239.08x m/s direction of motion of the second helium 1491239.08m/s the negative x direction (b) by applying the results if the original beryllium atom is at rest to a frame of reference moving with the original beryllium atom and then switching to the reference frame in which the beryllium is moving of the first hellum (magnitude)491239 08x m/s 491239.08 x m/s velocity of the second helium (magnitude) 149123908x m/s direction of motion of the second helium the negative x direction

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.
