Answer:
3763.2 Joules
Explanation:
GPE = mgh
m = 120kg
g = 9.8
h = 3.2 m
GPE = (120)(9.8)(3.2)
GPE = 3763.2 Joules
What role do electromagnets play in making a motor spin?
Answer:
I'm going to try to explain it to you easy as possible so basically when a motor is placed between two poles of another magnet a current from a voltage flow to the coil and a magnet field is produced around the electromagnetic and the poles of the magnet interact with the poles from the electricmatic causing the motor to turn in more coils growing stronger into the motor

A student named Bob is on a bike and the mass is 50 kg. The force causes the student to accelerate at 3 m/s to the power of 2. Calculate the net force that causes this acceleration.???
Answer:
150 N
Explanation:
Force is equal to mass times acceleration. 50 kg accelerating at a mass of 3m/3² is undergoing a force of 150 m/s², or 150 Newtons

Which type of wave can travel through empty space?
PLZ HELP ME BEST ANSWER WILL GET BRAINLIEST
AND IM SRS ABT THIS QUESTION
Answer:
Electromagnetic waves.
Explanation:
Electromagnetic waves include microwaves, X-rays, gamma rays, and light waves, it carries energy and it can travel through matter or empty space.
Answer:
Electromagnetic waves or Light Waves
Explanation:
"Electromagnetic waves carry energy. The waves consist of transverse vibrations in electrical and magnetic fields, not vibrating particles. Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum)."

A 50 kg object is accelerating to the right at 5 m/s2. What is the net force acting on the object?
Answer:
250 NExplanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 50 × 5
We have the final answer as
250 NHope this helps you
How energy and power are different ???
Answer:
Explanation:
Energy is what makes change happen and can be transferred form one object to another. ... Power is the rate at which energy is transferred. It is not energy but is often confused with energy. The watt is the most commonly used unit of measure for power.

Question: If you are traveling by train and the trip is 125 miles and takes 2 hours winding through the mountains, a) whats average speed? b) how would this be different if the train in each of the following situations- Train at rest, Train traveling at constant speed in a straight line, and the Train with a braking force (the train in the middle of coming to a stop)
PLEASE ANSWER ALL ASAP
Answer:
Average speed 62.5 miles an hour. If the train was traveling at a constant speed in a straight line it would be much faster on getting to its destination
Explanation:
There are three types of friction. ______________ friction occurs when an object is not moving. ______________ friction occurs when an object is moving against another surface. ______________ friction occurs in the case of wheels or other round objects. The amount of friction depends on two things.First, how ______________ the surfaces are; and second, how ______________ the object is. It is ______________ to keep an object moving than to start it moving. This is because static friction is ______________ than sliding friction.
Word Bank:
static
sliding
rolling
bumpy
heavy
easier
greater
Answer:
1. Static friction = not moving
2. sliding friction = moving
3. rolling friction = wheels
4. bumpy the surfaces are
5. how heavy the object is
6. it is easier to keep an object moving
7. static friction is GREATER than sliding friction

Which factor leads to interference between waves? (2 points)
Select one:
a. A varying phase relationship between waves
b. Similar wave amplitudes
c. Unequal wavelengths
d. Radiation through different regions
Due to the sheer short wavelength, the angle at which constructive interference in between waves occurs is unequal wavelengths.
Unequal wavelengths:Two conditions must be met to create a steady and clear interference pattern: both wave sources must be cohesive, meaning they must emit identical waves with a consistent phase difference. The waves should be monochromatic, meaning that they will have only one wavelength.As a result, the interference between waves would be limited by unequal wavelengths.Find out more about the Unequal wavelengths here:

1. Spring force is proportional to stretch distance, F=kd. Do you expect doubling the stretch distance double the force?
Yes
No
Answer:
Yes
Explanation:
The spring force is given as:
F = kd
F is the spring force
K is the spring constant
d is the magnitude of the stretch
Since k is a constant, therefore, doubling the stretch distance will double the force.
Both stretch distance and force applied can be said to be directly proportional to one another.
Answer:
Yes!
Explanation:
An object has an x-momentum of 8.5 kilogram-meters/second and a -momentum of 9.8 kilogram meters/second. What Is resultänt
momentum of the object?
OA 15.5 kilogram-meters/second
OB. 14.8 kilogram-meters/second
0c 12.97 kilogram-meters/second
OD. 16.8 kilogram-meters/second
Answer:
The resultant momentum is 12.97 kg.m/s. Choice: c
Explanation:
Momentum
The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".
As a vector, it can be expressed by its rectangular components:
[tex]\vec p = p_x\mathbf{i}+p_y\mathbf{j}[/tex]
The magnitude of the momentum is:
[tex]\mid \mid \vec p \mid \mid =\sqrt{p_x^2+p_y^2}[/tex]
The object described has an x-component of:
px=8.5 Kg.m/s
And a y-component of:
py=9.8 Kg.m/s
Thus, the magnitude of the momentum is:
[tex]\mid \mid \vec p \mid \mid =\sqrt{8.5^2+9.8^2}[/tex]
[tex]\mid \mid \vec p \mid \mid =\sqrt{72.25+96.04}[/tex]
[tex]\mid \mid \vec p \mid \mid =\sqrt{168.29}[/tex]
[tex]\mid \mid \vec p \mid \mid =12.97[/tex]
The resultant momentum is 12.97 kg.m/s. Choice: c

Where is the planet moving faster?
You are in a plane, and hit a bird as your flying, how can this impact produce a large impulse, despite the plane being much bigger
It effects the balance of the plane, and slows it. Also you are likely moving faster than the bird, and it would be almost as if you are hitting a brick. However when it makes the plane impulse then it means the sudden loss of speed (even if it is a small bird) that is keeping the plane in the air causes the planes engines to struggle for a short amount of time, while it tries to recover the little amount of speed it has lost (the engines HAVE to regain full speed or the plane will turn to the ground, maybe not ALL the way but it still will lower the nose.

In baseball/softball how many players play in the field at one time?
Answer:
10 players
Explanation:
The attracting and repelling forces of magnets are used in countless objects, from refrigerator doors to maglev trains.
Refrigerator doors use the attraction of magnets to stay closed, while maglev trains use magnetic repulsion to hover
above rails. The center magnet in the picture is hovering between two magnets, making it appear to float. Which best
explains how the center magnet is able to hover between two other magnets?
Answer:
the magnets can hover because like poles repel each other, causing the magnet in the center to float. so you have a South Pole of the top magnet facing down to the South pole of the middle magnet and the bottom would have to be North on top and south on the bottom.

the stolen valor act
Answer:
The Stolen Valor Act of 2005, signed into law by President George W. Bush on December 20, 2006, was a U.S. law that broadened the provisions of previous U.S. law addressing the unauthorized wear, manufacture, or sale of any military decorations and medals. The law made it a federal misdemeanor to falsely represent oneself as having received any U.S. military decoration or medal. If convicted, defendants might have been imprisoned for up to six months, unless the decoration lied about is the Medal of Honor, in which case imprisonment could have been up to one year. In United States v. Alvarez, the U.S. Supreme Court ruled that the Stolen Valor Act was an unconstitutional abridgment of the freedom of speech under the First Amendment, striking down the law in a 6 to 3 decision.
