A cinder block is sitting on a platform x m high. It weighs 79 Kg. If the block has 15 484 Joule. Find x ? (g = 9.8 m/s2)

Science and technology are interdependent. advances in one lead to advances in the other. give an example of this phenomenon.

Alfred pushes on a heavy box, but cannot move it. the box has a lot of inertia motion friction gravity

Photoelectrons with a maximum speed of 6.50 x 107 m/s are ejected from a surface in the presence of light with a frequency of 6.75 x 1014hz. if the mass of an electron is 9.10 x 10-31 kg, calculate in joules the maximum kinetic energy of a single electron. 3.84 x 10-15 j 1.92 x 10-15 j 5.92 x 10-23 j 3.07 x 10-16 j
