How would the force of gravity between two objects change if the distance between them were to decrease by half?
O A. The force between them jould be 1/4 the force with the initial
separation.
OB. The force between them would be 2 times larger than with the
initial separation.
C. The force between them would be 4 times larger than with the
initial separation.
O D. The force between them would be 1/2 the force with the initial
separation.

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.

How is zig zagging a form of acceleration?

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
