Explain why When a small drop of detergent is placed on water, the needle moves rapidly away from it and sinks when more detergent is added.(Assume that the detergent does not affect the density of water)

The extremely high temperatures needed to trigger nuclear fusion are proposed to be generated by laser irradiating a spherical pellet of deuterium and tritium fuel of diameter 1.8 mm. (a) determine the maximum fuel temperature that can be achieved by irradiating the pellet with 200 lasers, each producing a power of 550 w. the pellet has an absorptivity 0.3 and emissivity 0.8.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
