Marissa designs a robot that goes on a mission to mars. the acceleration of gravity on mars is 3.7 m/s^2. the robot has a mass of 18 kg.

a. how does the mass of the robot change once it gets to mars? explain

b. how does the weight of the robot change once it gets to mars? explain

a) The amount of molecules, details, wires etc. in the robot hasn't changed, so the mass does not change.

b) Weight is mass times g, so since the mass hasn't changed and the acceleration of gravity is smaller on Mars, the weight will decrease there.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
