Why would an airplane flying at 10,000 meters above the ground have more gravitational potentialenergy than the same airplane flying at 1,000 meters above the ground?

Answers

Answer:

The gravitational potential energy (gpe) possessed by an object or body is directly proportional to the height of the object or body.

Explanation:

Gravitational potential energy (GPE) is an energy possessed by an object or body due to its position above the earth.

Mathematically, gravitational potential energy is given by the formula;

G.P.E = mgh

Where;

G.P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Generally, the gravitational potential energy (gpe) of an object or body is directly proportional to the height of the object or body. Thus, the gravitational potential energy of a body increases as the height of the body increases.

In conclusion, an object with a higher height would have a higher gravitational potential energy.

What is the potential of a 35kg child sitting at the top of a slide that is 3.5m above the ground? What is her kinetic energy if she moves down the slide at a speed of 5.0m/s??

Answers

Ep = mgh
     = (35)(9.8)(3.5)
     = 1200.5 J

Ek = (1/2)(mv^2)
     = (0.5)(35)(5^2)
     = 437.5 J

An automatic response to a stimulus is called a reflex.

Answers

If you are asking if it is true or false, the correct answer is true. Reflex is an automatic response to a stimulus. Reflex is a stimulus that will allow an individual to respond to an event in which an organism will need to do in order for survival.
