What would the acceleration of the astronaut be due to the earth's gravity at this point if the moon was not there? the value of the universal gravitational constant is 6.672 × 10−11 n · m2 /kg2 . answer in units of m/s 2 ?

The least penetrating form of radiation is

Question part points submissions used suppose that 2 j of work is needed to stretch a spring from its natural length of 26 cm to a length of 36 cm. (a) how much work is needed to stretch the spring from 28 cm to 32 cm? (round your answer to two decimal places.)

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
