How much energy is given to each coulomb of charge passing through a 6 V battery

Answers

Answer 1

Answer: 1 volt = 1 joule per coulomb. Current doesn't actually pass 'through' a battery. But if it did, then each coulomb would gain or lose 6 joules in traversing 6 volts, depending on its sign, and whether it climbed or fell.

Answer:

The correct option is (B)mantle convection

Explanation:

Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.

The answer is B. Mantle convection.

A man is trying to drag a small tree that he cut down. If the static coefficientof friction of the tree on the ground is 0.5 and the tree weighs 480 N, what is
the minimum amount of horizontal force that the man will need to apply so
that the tree will start moving?

A. 240 N
B. 360 N
C. 480 N
D. 120 N

Answers

Answer:

120 N

Explanation: First we shoud consider the forces acted on a tree

Friction foce - acting opposite to the moving direction

Weight - Directly acting downwards

Reaction - Directly acting on upwards

For minimum required force should be equal to the friction force

F = μ R

F = 0.5×480

= 120N

4. What type of smog do we experience in the United Sta5. Why is it harmful?6. What is one resultof air pollution?7. Rain that contains more acid than normal is called8. How does acid rain harm our environment?How are Americans improving air quality?

Answers

4. We experience brown smog, especially in Denver and LA.
5. It is harmful because brown smog is composed of NOx's which react with water vapor in the atmosphere and create acid rain.
6. One result of air pollution is acid rain.
7. Acid rain.
8. Acid rain harms our environment by decreasing the pH of the soil which can harm plant life and bacteria, disrupting the ecosystem.
9. Americans are improving air quality by passing laws such as the Clean Air Act of 1990 which puts limits on the amount of air pollutants cars, factories, ect can release into the atmosphere.

Side note: if you enjoy learning about this sort of thing or how humans impact the world, and haven't taken AP Environmental Science you totally should. It's a very eye opening class and I enjoyed it very much this year!

When Jackson throws a tennis ball in a straight path, what two forces cause the ball to eventually stop moving?

Answers

After Jackson lets go of the ball, there are two forces on it
that influence what it's going to do. They are gravity and
air resistance.

Air resistance is just plain friction. As long as the ball continues
to move through air, it loses kinetic energy to the air and gradually
slows down.

While the ball is in the air, there are no other forces on it that cause
it to stop moving.

If you absolutely must have another one, it doesn't occur until the
ball hits the ground. But that isn't even another force. It's just more
friction, from scraping against concrete and grass.

Gravity pulls the ball down to the ground. But gravity doesn't make
the ball stop moving. In fact, gravity tries to make it move faster and
faster, and gravity would succeed if it weren't for all the friction that
the ball encounters.

Well, the force that originally caused it to start moving was inertia, but the forces that cause it to stop are friction and gravity. Gravity pulls the object towards the center of the Earth, causing it to slow and eventually stop, and friction is the resistance between the ball and the ground (or whatever).

Hope this helps!
