Answer 1

A.
When the ball is coming in my direction, I hit the ball which changes its motion. If I had not done that, the ball would have kept on going until another force acted on it.

B.
The weight of the bowling ball and its acceleration increases its force, which allows for it to knock over the bowling pins with ease. Had I thrown lighter, its force would decrease.

A submarine fills a special storage area known as ballast with water in order to increase its density. This allows it to dive deeper into the ocean. When a submarine needs to rise rapidly, compressed air is used to push the water out of the ballast. What effect does replacing the water in the ballast with air have on the submarine?

Answers

Answer:

The submarine will rise.

Explanation:

To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. This increases the vessel's displacement.

Slow cooling of hot magma leads to the formation of ___________ crystals

Answers

Answer:

Slow cooling leads to the formation of large crystals. If the crystals remain undisturbed while cooling, they grow according to a regular pattern. Magma closer to the surface cools much faster than magma that hardens deep below ground. With rapid cooling, there is no time for magma to form large crystals.

Just count the number number of substances, the subscript(number at the bottom) tells you how many of it there is. Then you check if there is a coefficient(number in front of all the substances) and if there is a number you multiply you previous answer by it. The coefficient tells you how many molecules there is. Your final answer is the number of atoms!

An object has a mass of 960 g and a volume of 15cm3 what’s the density?

Answers

Explanation:

density = mass ÷ volume

mass = 960g

volume = 15³ = 15 × 15 × 15

= 3375 cm

density = 960 ÷ 3375

= 0.28 g/cm³

Answers

Answer:

The object is moving forward

Explanation:

Hop this helps :)

Answer: The orb is attracted to the pipe at first because the orb has a positive charge. As soon as the orb touches the pipe, it picks up a negative charge. Since the pipe is negative and the tinsel orb is now negative, they repel away from each other and the orb levitates!
