Answer : The rocks and debris would never accrete into a planet.

Explanation : Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force the rocks and debris would not come together to form a clump.

So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet.

The correct answer is B. The rocks and debris would never accrete into a planet.

Explanation:

Gravity refers to a force of attraction between objects due to their masses. This force is described through the formula F= G M m/ r2 in which G is equal to the gravitational constant, M and m describe the mass of objects, and r refers to the distance.

Moreover, gravity was essential for the formation of planets, stars and other elements in the universe, because this caused gas, dust, rocks, and other particles or elements to aggregate or accrete into planets and other celestial bodies. Moreover, gravity is responsible for phenomena such as planets orbiting. The previous idea implies that without gravity the formation of planets would not have possible and therefore "the rocks and debris would never accrete into a planet".

A parallel-plate capacitor is disconnected from a battery, and the plates are pulled a small distance farther apart. Does Q incr

kolezko [41]

Answer:

Q stay the same

Explanation:

Charging of capacitor is done by battery . If battery is disconnected , charging will stop . There will not be any discharging as plates are separate . So pulling the plates apart will not affect the charge lying on the capacitor . It will decrease its capacity and increase its potential , keeping its charge constant.

Your roommate drops your wallet down to you from the third-floor window of your apartment, which is 11.5 m from the ground. What

Aneli [31]

Answer:

15 m/s

Explanation:

Using the law of conservation of energy, potential energy equals kinetic energy hence

$mgh=0.5mv^{2}$

Therefore

$v=\sqrt{2gh}$

where g is the acceleration due to gravity, m is the mass of the object, h is the height and v is the speed of the wallet

Taking g as 9.81 then

$v=\sqrt{2\times 9.8\times 11.5}=15.02098532 m/s\approx 15 m/s$

As a pendulum moves toward the equilibrium position, velocity and acceleration . As the pendulum moves away from the equilibrium

STatiana [176]

Answer:

As a pendulum moves toward the equilibrium position, velocity increases and acceleration decreases. As the pendulum moves away from the equilibrium position, velocity decreases and acceleration increases.

Explanation:

Using the law of conservation of energy, we know that Em1=Em2.

Em1 (at the highest point) = Eg + Ek, where Ek is 0

Em2 (at the equilibrium point) = Eg +Ek, where Eg is 0

This makes sense. At the highest point, the pendulum is at its maximum height. At this point, however, it stops moving, so its velocity is 0. At the equilibrium point, the pendulum is at its lowest height (i.e. h=0). At this point, however, its moving at its maximum velocity. This velocity is constant, which means that acceleration is 0.

When you see Marjorie, she is swinging a bucket of water around in a circle. The speed of the bucket of water does not change as

ser-zykov [4K]

Answer:A

Explanation:

Since the bucket of water is constantly in motion it implies a force must be acting on it which allows it to change its Position constantly.

A constant gravity Force must be acting on water . In addition to gravity force a centripetal force must be acting on the water inside the bucket.

Bucket must move with certain velocity in order to avoid spilling of water.
