A boat, which moves at 34 miles per hour in water without a current, goes 1147 miles upstream and 1147 miles back again in 68 hours. Find the speed of the current to the nearest tenth.

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.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

the amount of current in the coil

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
