If an object has a mass if 20kg what is the force of gravity acting on it on earth

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.

In physics the desire of an object to keep doing what it is doing is termed?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving
