Calculate the minimum velocity which a space probe needs to be given to escape from the gravitational field of a star if it starts 1.5x10^11m from the centre of the star. The mass of the star is 3.3x10^30

Research the neutrino using the internet and report your findings. in a nuclear decay, the nucleus of an atom splits apart. larger particles can be detected and their masses and velocities can be recorded. explain how the existence and properties of the neutrino could be predicted using the conservation laws.

What are the three ways that an object can accelerate

What is the speed of an object at a given moment?
