How could you set up the Strong and Weak magnets to show Barry that strong magnets and weak magnets can BOTH repel and attract object's?
Answer:
To show that magnets repel, you must place the strong and weak magnets to another magnet with their poles being both south or both north facing eachother.
To show they attract, place opposite poles near eachother.

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

why do the lights in your home come on almost instantaneously when you turn on the switch?
Answer:
here you go
Explanation:
Why do your lights actually come on almost instantaneously? ... Wiring the house in parallel does not make a difference – there is no current flowing through the light bulb when the switch is off no matter how the house is wired. If there were a current already, the light would be on!
what is the energy of light for a single photon that has a wavelength of 347 nm?
The energy of light for a single photon that has a wavelength of 347 nm is 5.698 × 10-¹⁹ J
HOW TO CALCULATE ENERGY:
The energy of a photon of light can be calculated by using the following formula:E = hf
Where;
E = energy of photon (J)h = Planck's constant (6.626 × 10-³⁴J/s)f = frequency (Hz)However, the frequency must first be calculated using the formula as follows:λ = v/f
Where;
λ = wavelengthv = speed of light (3 × 10⁸m/s)f = frequencyf = v ÷ λf = 3 × 10⁸ ÷ 347 × 10-⁹f = 3/347 × 10⁸+⁹f = 0.0086 × 10¹⁷ Hzf = 8.6 × 10¹⁴ HzE = 6.626 × 10-³⁴ × 8.6 × 10¹⁴E = 56.98 × 10-²⁰E = 5.698 × 10-¹⁹ JTherefore, the energy of light for a single photon that has a wavelength of 347 nm is 5.698 × 10-¹⁹ J.Learn more at: https://brainly.com/question/13407202?referrer=searchResults
Using your knowledge of momentum explain why cars are designed to have crumple zones?
Answer: I think cars are designed to have crumble zone because lets say you're going 60-70 mph and you hit a brick wall that cant move, it would be a very hard jolt causing the beings inside to get thrown forward, but if it has a crumble zone it would slow the the jolt from is slowing down in the hit.

g is acceleration due to gravity [ vertically: g is 10 m/s². horizontally: g is 0 ]Distance between gas molecules in the case of:
-Increase in temperature
-Decrease in temperature
-Increase in volume
-Decrease in volume
-Increase in pressure
-Decrease in pressure
Answer:
-Increase in temperature: increase
-Decrease in temperature: decrease
-Increase in volume: increase
-Decrease in volume: decrease
-Increase in pressure: increase
-Decrease in pressure: decrease
Explanation:
-Increase in temperature:
● Molecules gain kinetic energy and move fast thus increasing distance
-Decrease in temperature:
● Kinetic energy of molecules decrease so they have smaller distance
-Increase in volume:
● Molecules have more space to move around so distance increase
-Decrease in volume:
● Less space, molecules collide with each other because of decreased distance thus increasing pressure
-Increase in pressure
● Molecules collide with each other and the walls of container increasing pressure so molecules move faster and it increases distance
-Decrease in pressure:
● Molecules collide with each other and walls of container less frequently so distance between molecules decrease
a tennis ball is launched from the floor at a velocity of 90 m/a at an angle of 13 degrees to the horizontal. calculate its range
Answer:
~186
Explanation:
1) R= (V^2 × sin A ) /g
V=90 m/a
A= 13°
g= 9.8 or 10 (I will take 9.8 for right result)
R= (90^2 × sin 13) / 9.8 = 185.928932672 ~ 186

Describe the difference between distance, position, and displacement
Answer:
Explanation:
Position is the location of the object (whether it's a person, a ball, or a particle) at a given moment in time.
Displacement is the difference in the object's position from one time to another.
Distance is the total amount the object has traveled in a certain period of time.

As shown above an adhesive has been applied to contacting faces of two blocks so that the blocks interact with an adhesive force that has a magnitude, Fadhesion A tension, T, is exerted by a wire attached to the upper blocks causing the blocks to remain at rest The two blocks have weights, Wbottom and Wtop. Which of the following must be true? (1 point) ♡ O Wtop=T OT = Wtop - Fadhesion O Wbottom Fadhesion O T = Wbottom + Wtop + Fadhesion
The magnitude of the adhesive force allows the top block to remain
attached to the bottom when the blocks and the wire are balanced.
The option that must be true is; [tex]\mathbf{W_{bottom} = F_{adhesion}}[/tex]
Reason:
The tension exerted by the wire attached to the top block = T
Magnitude of the adhesive = [tex]F_{adhesion}[/tex]
Weight of the top block = [tex]W_{top}[/tex]
Weight of the bottom block = [tex]W_{bottom}[/tex]
Given that with the exertion of the tension, the two blocks remain at rest, we have;
T = [tex]W_{top}[/tex] + [tex]W_{bottom}[/tex]The adhesive causes the bottom block to remain attached to the top block, we have;
Therefore, the magnitude of the adhesive force adds the bottom weight, to the top, weight, which gives;
The magnitude of the adhesive force = The weight of the bottom block
Therefore;
[tex]W_{bottom}[/tex] = [tex]F_{adhesion}[/tex]Learn more here:

Q1. A 130 N horizontal force keeps a 30 kg chair moving at a constant velocity. Find the
coefficient of kinetic friction between the chair and the floor.
The coefficient of kinetic friction between the chair and the floor is 0.442.
The given parameters;
horizontal force on the chair, F = 130 Nmass of the chair, m = 30 kgThe normal force on the chair is calculated as follows;
Fₙ = mg
Fₙ = 30 x 9.8 = 294 N
The frictional force between the chair and the floor is calculated as follows;
Fk = μFₙ
The net force on the chair is calculated as follows;
[tex]\Sigma F_x = 0\\\\F- \mu_k F_n = 0\\\\130 - \mu_k (294) = 0\\\\\mu_k = \frac{130}{294} \\\\\mu_k = 0.442[/tex]
Thus, the coefficient of kinetic friction between the chair and the floor is 0.442.

what language is thathow do I literally understand thatAn object is travelling at a velocity of 5m/s to the right for 5 seconds. If NO forces are applied to the object, what will the velocity of the object be after 5 seconds.
Answer:
Below
Explanation:
We can use this formula to find the final velocity of the object :
vf = vi + at
Now, because no force is applied to the object, the acceleration of this object will be 0 according to Newton's 1st law!
vf = 5m/s + (0)(5)
vf = 5 m/s
