ELECTROMAGNET WAVES
Travel through what?
Carry energy, often called what?
Emitted by what?
Three Examples of electromagnetic waves.
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Example: Radio waves, microwaves, visible light, and x rays
Henry is at the state fair. At one booth he throws a 0.70 kg ball forward with a velocity of 22.0 m/s in order to hit a 0.15 kg bottle sitting on a shelf. When the ball makes contact the bottle goes flying forward at 29.0 m/s. What is the velocity of the ball after it hits the bottle?
The velocity of the ball after it hits the bottle is 15.8 m/s
Let m₁ represent the mass of the ball, m₂ the mass of the bottle, u₁ the velocity of ball before impact, u₂ the velocity of bottle before impact, v₁ the velocity of ball after impact and v₂ the velocity of bottle after impact.
Given that:
m₁ = 0.7 kg, m₂ = 0.15 kg, u₁ = 22 m/s, u₂ = 0, v₂ = 29
momentum before impact = momentum after impact, hence:
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
0.7(22) + 0.15(0) = 0.7v₁ + 0.15(29)
0.7v₁ = 11.05
v₁ = 15.8 m/s
Therefore the velocity of the ball after it hits the bottle is 15.8 m/s

If the mass of an object is 100 and Net force is 400, what would be the Acceleration?
And explain.
Answer:
[tex]4m/s^{2}[/tex]
Explanation:
I'm assuming the units for force and mass are Newtons and kilograms, respectively.
Rearranging Newton's first law (F=m*a) to solve for acceleration:
F=m*a
[tex]a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}[/tex]
The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.

A cart of weight 20 N is accelerated across a level surface at 0.15 m/s?. What net force acts on
the wagon?
The net force that acts on the cart of wagon is calculated as 3N
HOW TO CALCULATE NET FORCE:
The net force of a body can be calculated by multiplying the mass of the body by its acceleration. That is;Force (N) = weight (N) × acceleration (m/s²)According to this question, a weight of 20N accelerated across a level surface at 0.15 m/s². The net force can be calculated as follows:F = 20 × 0.15
F = 3N
Therefore, the net force that acts on the cart of wagon is calculated as 3N.Learn more at: https://brainly.com/question/18109210?referrer=searchResults

Kevin and Kisha are ice skating. Kisha has a mass of 60 kg, and Kevin has a mass of 45 kg. As they face each
other, Kevin pushes off Kisha with a force of 54 N. Assume the friction between the skaters and the ice is
negligible.
t
Determine the magnitude of Kevin's acceleration.
Write your answer to two significant figures.
m/s
m
If Kevin with mass 45kg pushes Kisha with a force of 54N, the magnitude of Kevin's acceleration is 1.2 m/s²
Kisha's mass = 60 kg
Kevin's mass = 45 kg
Kevin pushes off Kisha with a force of 54 N
Since it was Kevin that pushed Kisha, and the required force is 54N, we can look for Kevin's acceleration using the equation below
F = ma
The considered mass is Kevin's mass
54 = 45a
a = 54/45
a = 1.2 m/s²
The magnitude of Kevin's acceleration is 1.2 m/s²

why does chelsea see sparks as she removes her clothes from the clothes dryer? conduction. induction. static discharge. loss of protons.
This is electrostatic phenomenon. Chelsea see sparks as she removes her clothes from the clothes dryer because of static discharge.
What is Static Electricity ?Static electricity is produced by friction when two materials are rubbed together.
Why does Chelsea see sparks as she removes her clothes from the clothes dryer?
The correct answer is because of static discharge.
For instance, when a glass rod is rubbed with silk or cellulose acetate with silk, the glass will become positively charged by loosing electron to the silk whereby becoming negatively charged.
Static discharge occurs during thunder and lightning, and when combing our hair during harmattan season.
Therefore, Chelsea see sparks as she removes her clothes from the clothes dryer because of static discharge.
