The energy an object possesses due to its form and position is know as
zvonat [6]
I believe the energy being described is the potential energy. Potential energy is the stored energy, it is the energy an object has because of its position or shape. It is also the energy possessed by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors. The major types of energy include the gravitational energy of an object that depends on its mass and its distance from the center of mass.

What is located in the exosphere?
Paha777 [63]
In the exosphere, there is thin air, since it is the uppermost level in the atmosphere. It is made mostly of helium and hydrogen. But, traces of other gases such as atomic oxygen and carbon dioxide can also be found in the exosphere.

Is it possible for an inverted pyramid to exist, like the one show here? Explain your answer.
Korvikt [17]

Answer:

Not possible, if we talk about real pyramids

Explanation:

There is no image shown in the question statement. However if we talk about the pyramids as we find them in Egypt, we cannot get a stable inverted pyramid because of the difficulty in terms of balancing it from its centre of mass. In theory one might balance the forces, but in actual, to balance all the load of the structure just on a point is extremely difficult.

However, the term inverted pyramid can be found in ecological system and also used as metaphors in English literature

The gravitational acceleration on Earth is 9. 8 m/s2. What is the weight of a car on Earth (to the nearest whole number) if it h
astraxan [27]

Hi there!

Recall the equation for weight.

W = Mg

W = Weight (N)

M = Mass (kg)
g = acceleration due to gravity (m/s²)


The weight of an object depends upon its MASS and the strength of the GRAVITATIONAL field. We can solve for weight:

W = 1360 * 9.8 = \boxed{13,328 N}
