Answers
Answer:
D. the sound of the explosion would not be transmitted back to their ship.
Explanation:
Sound is a type of mechanical wave so it needs a solid to move through. Since space is a vacuum, the Klingon crew would not be able to hear the explosion.

The candy before was fluffy, and the candy after was compacted.
Explanation:
Final answer:
The cloudy cotton candy was light and fluffy due to the air incorporated in it. After Chanel made it dense, the candy became compact and heavier, as she decreased the volume and maintained or increased the amount of sugar.
Explanation:
The cotton candy that Chanel had originally was described as being in a cloudy shape. This suggests that it was light, fluffy, and probably had a lot of air incorporated into it, which is why it was able to maintain such a shape. After she manipulated it to make it more dense, the cotton candy would have lost its cloudy appearance. Instead, it would have become heavier and more compact, because decreasing the amount of air in it increases its density. In other words, the volume of the cotton candy has decreased, but the amount of sugar within that volume has remained the same or increased.

the resistors are connected in parallel, just as the minimum resistance to the
flow of vehicular traffic is achieved when several lanes are built in parallel.
When 5 equal resistors are connected in parallel, the net resistance of their
combination is just 1/5 of the value of each one.
So 5 equal resistors in parallel, each with a resistance of 1/5 ohm, have a
combined net resistance 0f 1/25 ohm.

The pellets in a shotshell start to spread or scatter as soon as they are fired. This dispersion will increase as the pellets travel farther. Shotgun barrels feature a choke to regulate this pellet pattern. The shotgun barrel's choke is the constriction at the muzzle end.
How long is a shot string?
At 20 yards, it can be roughly 5 feet long, and at 30 yards, it can be 8 feet long. The variance is brought on by the pellets' distortion as they move along the barrel.
The full choke features the tightest shot pattern and is the tightest choke. The pellets are kept together for a longer distance thanks to this choke. It is typically used for shots that are further than 40 yards.

Explanation :
The momentum of an object is defined as the product of its mass and the velocity with which it is moving. It is denoted as p.
Mathematically, it is written as :
m is the mass of an object
v is the velocity
So, it is clear that the momentum of an object is directly proportional to its velocity.
The statement "as a moving object's velocity decreases, its momentum decreases" is absolutely true.
