A ball is thrown horizontally from the top of a building 100m high. The ball strikes the ground at a point 120 m horizontally aw
pshichka [43]

Answer:

44.3 m/s

Explanation:

Given that a ball is thrown horizontally from the top of a building 100m high. The ball strikes the ground at a point 120 m horizontally away from and below the point of release.

What is the magnitude of its velocity just before it strikes the ground ?

The parameters given are:

Height H = 100m

Since the ball is thrown from a top of a building, initial velocity U = 0

Let g = 9.8m/s^2

Using third equation of motion

V^2 = U^2 + 2gH

Substitute all the parameters into the formula

V^2 = 2 × 9.8 × 100

V^2 = 200 × 9.8

V^2 = 1960

V = 44.27 m/s

Therefore, the magnitude of its velocity just before it strikes the ground is 44.3 m/s approximately

Which statement about fossil fuels is false?
FromTheMoon [43]

The statement about fossil fuels is false is <u>C. They are dependent on location</u>, 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 has the form of gas.

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 has a solid form.

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 has a liquid form

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.
