Which of the following statements is true about the advantages and disadvantages of using different energy resources?
A Wind power is an expensive, nonrenewable source of energy for the production of
electrical energy
B Solar power is a clean, renewable source of energy, but quite expensive and not
dependable on a daily basis.
C Coal is a safe and effective renewable source of energy used in the production of
electricity.
D Nuclear power is a cost effective, nonrenewable energy resource that leaves behind no
waste

a person with a mass of 106kg has a weight of 1060n

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

pretty sure it's false

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.
