What happens to the average kinetic energy of water molecules as water freezes? It decreases as the water absorbs energy from it
Morgarella [4.7K]

Answer:the average kinetic energy is directly proportional to the temperature . When water freezes, the temperature decreases and therefore, the average kinetic energy will also decreases as well.

A father is trying to teach his child to ice skate. As the child stands still, the father pushes him forward with an acceleratio
rjkz [21]

Hi there!

We can use Newton's Second Law:

\Sigma F = ma

∑F = net force (N)

m = mass (kg)

a = acceleration (m/s²)

We are given the mass and acceleration, so:

∑F = 20 · 2 = <u>40 N</u>

A camera has a single converging lens with a fixed focal length f. (a) How far should the lens be from the film (or in a present
Varvara68 [4.7K]

Answer:

a) Due to the characteristic that a converging lens focuses light rays from infinity and parallel to its main axis. Therefore, the lens should be placed at a distance "f" from the film, in this way it will form the image of the object placed at infinity in said film.

b) Since the converging lens produces an image of an object placed at a distance of 2f, the lens must be placed at the same distance (2f), so that this object that is placed at a distance of 2f is focused.

Which of the following statements are true?a. Earth's geographic south pole is also a magnetic south pole. b. Scientists have ev
ANTONII [103]

Answer:

c, d, and f.

Explanation:

Let us look at each of the statements one at a time:

a. Earth's geographic south pole is also a magnetic south pole.

This is not true. Earths magnetic south pole is slightly off (2,860 km away) from earth's geographical south pole.

b. Scientists have evidence that single isolated magnetic poles, called magnetic monopoles, exist.

Nope. So far no evidence yet exists that hypothetical magnetic monopoles exist.

c. The north pole of a bar magnet will attract the south pole of another bar magnet.

True, since opposite ends of a magnet attract and like ends repel.

d. The south poles of two bar magnets will repel each other.

Also true since like poles of a magnetic repel each other.

e. The north poles of two bar magnets will attract each other.

No, the north poles of two magnets will repel each other since they have the same polarity.

f. Earth's geographic north pole is actually a magnetic south pole.

Yes. If you call the point of the needle that points north the north pole of the compass,<em> then it points north because it is attracted to the south pole of earth's magnetic field.</em> (like repel opposites attract)
