Answer: Maximum potential energy is at point R. (C)
Explanation: At point R, the ball lost all of its kinetic energy since it stopped moving upwards. It then gained potential energy due to gravity, and started moving downwards.
The answer is: "
44 km " ;
or; write as: "
44.333 km " .
___________________________________________________________Explanation:___________________________________________________________(70 km + 63 km) ÷ (2 + 1 ) = 133 km ÷ 3 = "
44 km " ;
or; write as: "
44.333 km " .

Answer:
μ = 0.6
Explanation:
F = μN
N = mg
F = μmg
3 N = μ*0.5 kg * 9.8 m/s²
μ = 3/(0.5*9.8) = 0.6
Temperature lower than absolute zero is not possible. Lower than absolute zero a gas contain negative pressure and volume which is not possible. temperature is the energy created by moving atoms absolute zero is a complete stand still you can make particles move to the end of the universe but the coldest temperature will be stuck at the point where atoms are motionless
hope that helped :)
