The correct answer would be C. it moves at a constant speed. The troposphere(the layer our weather is in) is not nearly high enough for gravity to be different at different altitudes.
Answer:
The friction force acting on the object is 7.84 N
Explanation:
Given;
mass of object, m = 4 kg
coefficient of kinetic friction, μk = 0.2
The friction force acting on the object is calculated as;
F = μkN
F = μkmg
where;
F is the frictional force
m is the mass of the object
g is the acceleration due to gravity
F = 0.2 x 4 x 9.8
F = 7.84 N
Therefore, the friction force acting on the object is 7.84 N
Answer:
Energy is the ability for an object to do work.
Kinetic energy is energy which a body possesses while in motion.
Stored Energy = Potential Energy.
Speed is a measurement of how quickly something is able to move or operate.
Explanation:
Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter.
Answer:
Chemical Energy
Explanation:
Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.
