d. they are easy to use and transport

The statement about fossil fuels is false is C. They are dependent on location, and the rest are relatively true

Further explanation

fossil fuels or mineral fuels are natural resources that contain hydrocarbons such as coal, petroleum, and natural gas. Fossil fuels are formed because of the natural process of decay from organisms that died hundreds of millions of years ago. Dinosaurs, trees, and almost all living things that died were deposited on the ground and now have become petroleum, natural gas, or coal. Natural gas has the form of gas, liquid petroleum, and solid coal. due to differences in the pressure and heat, they receive in the bowels of the earth over millions of years ago. Fossil fuels are a type of non-renewable natural resources. Because this fossil fuel is formed from the process of sedimentation and decomposition of living things and takes millions of years. That is why, the utilization of this fuel must be done wisely and responsibly, besides that the sources of fossil fuels that are available are faster used up compared to the formation of new ones.

There are 3 types of fossil fuels and all three have different shapes, which are

natural gas is a fossil fuel in the form of gas. Natural gas is a mixture of hydrocarbons that has large expandability, high compressive strength, low specific gravity and naturally exists in the form of gas. Natural gas is collected underground with a variety of compositions contained in the oil content (associated gas).

Coal is a sedimentary rock that can burn. Formed from organic sediment and through the process of a forge. The main elements of coal are carbon, hydrogen, and oxygen. Coal is used as a raw material for making cement, steel, aluminum, and also as an energy source for power plants in several countries. In addition, there are many more benefits from coal. However, the wrong process in processing coal can have a negative impact on the environment. That is why many countries provide rules regarding the use of this coal.

Petroleum is the most widely used resource, both personally and industrially. Petroleum, which is still in raw condition, will go through several stages of processing until finally it becomes a finished product and is ready for use. Some processed petroleum products that are often used in daily life are gasoline, kerosene, and so on.

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts
