Explain the term "Acceleration due to gravity"

Physics

Answer:

"Acceleration due to gravity" typically refers to the increase in speed of a falling object due to the gravitational pull of the Earth. If jump out of a plane, your speed increases towards the Earth (or the center of the Earth really) due to the acceleration of gravity. If you throw a ball up in the air, it slows down and falls due to the acceleration of gravity.

I guess it's specified because the force of gravity is causing the acceleration in these instances; as opposed to some other outside force.

Half of the moon is always illuminated by the sun. Given that this is true, then what causes the moon to change phases throughou

ollegr [7]

It is true that only half of the moon is always illuminated by the sun. The reason why the moon changes it phases is because Moon orbits around the Earth, and due to this some areas of the half of the moon will not be lit by the sun.

If all of the forces acting on an object are balanced, then:

kondaur [170]

A. the direction the object is moving in will not change.

B. the acceleration of the object will be 0 m/s2

Explanation:

We can answer this problem by using Newton's second law of motion:

$\sum F = ma$

where

$\sum F$ is the net force acting on an object

m is the mass of the object

a is its acceleration

In this problem, all the forces acting on the object are balanced, therefore the net force is zero:

$\sum F=0$

which means that also the acceleration is zero:

$a=0$

Acceleration is equal to the rate of change of velocity: therefore, zero acceleration means that the velocity of the object does not change. We can now analyze the given statements:

A. the direction the object is moving in will not change. --> TRUE, because the velocity is not changing.

B. the acceleration of the object will be 0 m/s2 --> TRUE, as we stated above

c. the object will not be in motion. --> FALSE: we just know that its velocity is constant, but it can be different from zero

D. the velocity of the object will be 0 m/s. --> FALSE, for the same reason stated in C

Which of the following solutions should be chosen to help restore an ecosystem naturally? A. reintroducing an animal to the ecos

jolli1 [7]

Answer:

A. reintroducing an animal to the ecosystem

Explanation:

As generally, all know that for restoring an ecosystem naturally, it requires reintroduction of an animal to the ecosystem. As though it helps in reimposing the ecosystem back, and also helps to improve our ecosystem in natural surroundings, natural terrain, and population density. Basically reintroducing an animal is also required for the balancing of the ecosystem. As everything requires a properly balanced nature.
