Which labels best complete the diagram?Look at the diagram showing resistance and flow of
electrons.
OX: High resistance
Y: Low resistance
Z: Flow of electrons
X
N
X: Low resistance
Y: Flow of electrons
Z: High resistance
0 X: Flow of electrons
Y: High potential energy
Z: Low potential energy
X: Low potential energy
Y: High potential energy
Z: Flow of electrons

Answers

Answer: D

Explanation: Look at the figure, we can conclude that the correct answer is

X: Low potential energy

Y: High potential energy

Z: Flow of electrons

Because electrons flow where there is difference in potential energy. And electrons move from a region of high potential energy to a region of low potential energy.

Since the arrow is pointing to X, that means

Z is the flow of electrons, X is of low potential energy and Y is of high potential energy.

A rock is placed into a graduated cylinder containing 80 mL of water. What is the volume of the rock if the water level rises to the 120 mL mark?

Answers

If a rock is placed into a graduated cylinder containing 80 mL of water. then the volume of the rock would be 40 if the water level rises to the 120 mL mark

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

the density of the rock = mass of the rock /volume of the rock

As given in the problem A rock is placed into a graduated cylinder containing 80 mL of water.

The volume of the rock   =120 milliliter - 80 milliliter

                                         = 40 milliliter  

Thus, the volume of the rock would be 40 milliliters.

To learn more about density from here, refer to the link;

Ok so the expression that you will be doing is water-water+object. The actual expression is 120-80. The answer would be 40mL. Remember, don't forget your units! :)

You see lightning before you hear thunder because A) light waves can travel through a vacuum. Reactivate B) sound waves cannot travel through the air. C) light waves travel faster than sound waves. D) sound waves travel faster than light waves.

Answers

The answer is C) light waves travel faster than sound waves!
Once the light is gone, the air collapses back in and creates a sound wave that we hear as a thunder. Light travels through air at about 186,000 miles every second.However, sound wave travels through the air at 1,000 feet per second.
c) light waves travel faster than sound waves. if it's wrong please tell me...

when the box is moving ,it experiences a friction force of 20 N to the left , or toward the mover . what force does the mover need to applying order to keep the box moving to the right at 1 m/s?

Answers

Force = mass * acceleration
F = ma

Force = 20 Newtons
Mass = ?
Acceleration = 1 m/s

Here, we don't need to find the mass. Which is why this is such a tricky question. 

Instead, we need to find the force. 

Of course, we know already that force doesn't necessarily require a direction. 

F = 20 N

The force needed would be 20 Newtons, as said. 

The mover will need 20 newtons

2. The Moon takes 27.25 days to make one revolution around the Earth. Calculate how
many seconds it takes for the Moon to make one revolution around the Earth.

Answers

Answer:

1. 15.64 m/s

2. 2,354,400 seconds

Explanation:

1. 1mile is equivalent to 1609metres and 1hour is equivalent to 3600sec.

35mph = (35×1609)/3600

= 56315/3600

= 15.64 m/s

2. Note that 1 day ===> 24hrs

60min ==> 1hr

60sec ===> 1min

Thus 27.25 days = 27.25×24×60×60

= 2,354,400 seconds
