Water behind a dam has a certain amount of stored energy that can be released as the water falls over the top of the dam. It may be enough energy to turn a mill wheel or an electricity-generating turbine. Choose the term that best describes the type of energy stored in the water at the top of the dam. potential energy
kinetic energy
mechanical energy

Answers

Answer 1
Answer:

Answer:

The answer is potential energy

Explanation:

The potential energy is the energy possessed by a body by virtue of it position

For example the water at the top of the dam is being held at a height h above the bottom of the dam

Then the potential energy

PE= weight of the water* the height

PE= m*g*h

When a baseball player catches a baseball, the glove "gives" or moves backward. How does this movement affect the change in momentum of the baseball? The change in momentum increases because the impact time increases. The change in momentum decreases because the force decreases. The change in momentum stays the same because the ball still comes to a stop. The change in momentum depends on the initial speed of the ball and the time to stop.

Why do sound waves move faster through the ground than through the air?Particles of matter are packed more loosely in the ground than in the air. Particles of matter are packed more tightly in the ground than in the air. Air doesn’t contain any particles of matter to transmit sound waves.

A solid aluminum cube has sides each of length L . A second cube of the same material has sides four times the length of the first cube; i.e., 4 L . Compared to the first cube, the total surface area of the second cube is 1. twenty-seven times the first cube. 2. sixteen times the first cube. 3. sixty-four times the first cube. 4. eight times the first cube. 5. twenty-four times the first cube. 6. two times the first cube

Answers

Answer:

Option (2): Sixteen times the first cube

Explanation:

Surface \: Area \: of \: Cube = 6 {a}^(2)

(T.S.A \: of \: larger \: cube)/(T.S.A \: of \: smaller \: cube) = \frac{6 * 16 {l}^(2) }{6 * {l}^(2) } = 16

When the linear dimensions of a solid are multiplied by ' R ', the surface area of all or any part of it increases by R² , and the volume of all or any part of it increases by R³ .

If the sides of the second cube are 4 times the sides of the first one, then the second cube has (4²) = sixteen times the surface area of the first one (2), and it has (4³) = 64 times the volume of the first one.

An apple weighs at 1N. the net force on the apple when it is in free fall is?a. 0N
b. 0.1N
c. 1N
d. 10N
e. none of the above

Answers


The weight is the magnitude of the gravitational force between
the Earth and the apple.  There's no reason for the force to change
 just because the apple happens to be in motion.  If it weighs 1N on
the scale, then it weighs 1N while it's sailing over the fence, 1N on
the teacher's desk, and 1N while it's falling from the tree.

After a radioactive atom decays, it is the same element that it was before with no measurable change in mass. Which kind of decay has occurred, and how do you know? alpha decay because alpha particles have no mass beta decay because this kind of decay cannot change one element into another alpha decay because it creates a new isotope of the same element gamma decay because photons have no mass.

Answers

Gammadecay is the production of extremely high-frequency electromagnetic radiation . Gamma decay is the right answer from all types of decay.

What is gamma-decay?

Gammadecay is the production of extremely high-frequency electromagnetic radiation in order to stabilize the unstablenucleus. You must be well-versed in the various energylevels found in an atom.

The Nucleus has its own amount of energy. Gamma decay is the nucleus' method of transitioning from a higher energy level to a lower energy level by emitting high energy photons.

Hence gamma decay is the right answer for all types of decay. Because photons have no mass.

The cloud of interstellar dust and gas that forms a star is known as aA. white dwarf.
B. protostar.
C. red giant.
D. nebula.

Answers

D. nebula

Nebula is the cloud of interstellar dust and gas that forms a star. It is collborately shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entites. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
