Which statement is true? (2 points) hydroelectric power, a nonrenewable resource, is generated from moving water. propane, a renewable resource, is used in some heating systems. oil, a nonrenewable resource, is processed to make jet fuel. the energy from the sun, a nonrenewable resource, can be converted to electricity in solar cells.

Oil, a nonrenewable resource, is processed to make jet fuel.

Explanation:

A renewable resource is the one which is available in limited quantities on earth. It cannot be replenished.

The oil can be crued oil, which can be used as a source of energy as a mechanical energy required to run the jet. It is a nonrenewable resource as when it is consumed once cannot be used again.

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
