Two massive spheres of mass = 800 and = 2.5 are suspended by wires of negligible mass, which are attached to the ceiling as shown in the figure below. The smaller sphere is then raised from a height ℎ = 15 , in relation to its relaxing position, and released. When it reaches the lowest part of its trajectory, it collides with the largest sphere, which, in turn, is over a height . If the restitution coefficient of the system is = 0.65, determine the value of considering a central impact.

see diameter of a circle is 7 cm. therefore. radius will be half of diameter 7/2=3.5cm. Hopefully i helped

Explanation:

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

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.
