See for yourself how the forces of electricity and magnetism can work together by building a simple DC electric motor using simple materials you can find in any hardware store!

Electricity and magnetism are both forces caused by the movement of tiny charged particles that make up atoms, the building blocks of all matter. When a wire is hooked up to a battery, current flows through the wire because negatively charged electrons flow from the negative terminal of the battery toward the positive terminal of the battery because opposite charges attract each other, while similar charges repel each other. This flow of electrons through the wire is an electric current, and it produces a magnetic field.

In a magnet, atoms are lined up so that the negatively charged electrons are all spinning in the same direction. Like an electric current, the movement of the electrons creates a magnetic force. The area around the magnet where the force is active is called a magnetic field. Metal objects and other magnets that enter this field will be pulled toward the magnet.

The way the atoms are lined up creates two different poles in the magnet, a north pole and a south pole. As with electrical charges, opposite poles attract each other, while like poles repel each other.

Learn about electromagnetism and its many uses here.

Now let's watch it work as we build a motor.

What is true about the force between charges?
shusha [124]

Answer:

The statements A and D are true

The statements B and C are false

Explanation:

The force between charges can be explained by the Coulomb's Law.

According to Coulomb:

1 - Like charges always repel each other

2- Unlike or opposite charges always attrack each other

3- Force between 2 charges is given by:

F=k\frac{q_1q_2}{r^2}

where F is the force between 2 charges and r is the distance between 2 charges.

We can see that Force F is inversely proportional to the distance r

Which means that when F increase, r decreases and when F decreases, r increases

The graph represents the displacement of an object from its starting point as a function of time t. The object is traveling alon
iragen [17]

Based on the given displacement vs time graph, the object is at rest at a time interval of: B. 2 to 3 seconds

<h3>What is a displacement vs time graph?</h3>

A displacement vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled (covered) or displacement experienced by an object from its starting position with respect to the time when it has started moving.

In Science, a physical object being at rest simply means that the position of the object is not changing with respect to time. Thus, both the slope and velocity of the physical object would be equal to zero when it is at rest.

Between 0 to 2 seconds on the given displacement vs time graph (see attachment), this object is traveling at a constant, positive velocity. However, at a time interval of 2 to 3 seconds the object is at rest.

The spin of Earth creates the Coriolis effect. This effect causes which current patterns to occur? Choose all that apply
Komok [63]

Answer:

The correct answer is options (1) and (4).

Explanation:

Due to the rotation of the earth Coriolis force is generated. As the earth rotates from the west to the east, it changes the pattern of global wind and ocean water movement.

This force allows the ocean surface water to move in the clockwise direction in the northern hemisphere, and anticlockwise in the southern hemisphere.

Thus, the correct answer is options (1) and (4).

A pump is to deliver 10, 000 kg/h of toluene at 1140C and 1.1 atm absolute pressure from the Reboiler of a distillation tower to
motikmotik

Answer:

3.4093

Explanation:

NPSHa = hatm + hel + hf +hva

the elevation head is the hel

friction loss head is hf

NPSHa is the head of vapour pressure of fluid

atmospheric pressure head is hatm

log₁₀P* = A -\frac{B}{C+T}

A, B, C are fixed

log₁₀Pv = 4.07827-\frac{1343.943}{387.15-53.773}

= 4.07827 - 1343.943/333.377

=4.07827 - 4.0313009

= 0.0469691

we take the log

p* = 1.114218

we convert this value to get 111421.8

hvap = 111421.8 * 1/776.14 * 1/9.81

= 14.63

hatm = 1.1 *101325/1 * 1/9.81 *1/776.14

=14.64

hf = 7000/1 * 1/776.14 * 1/9.81

= 0.9193

NPSHa = 2.5

hel = 0.9193 + 2.5 + 14.63 - 14.64

hel = 3.4093
