Plz Answer All Questions. tysm.
Answer:
1) Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves. Destructive interference is when two waves superimpose and cancel each other out, leading to a lower amplitude.

Answer:
Turn off the second drip and then add a barrier with one slit. What do you observe on the right side of the wall? What do you observe on the left side of the wall? From a physics perspective, explain your observations of what is happening on both sides of the barrier.
Explanation:
The speed and amplitude of the waves are affected when hitting the barrier. The two waves reflect off the barrier and they travel in opposite directions.

A meterologist made these observations one day:
• In the morning, anocean wave hit a shoreline every 15 seconds.
• In the afternoon, an ocean wave hit the shorlinie every 30 seconds.
Identify whether the ocean waves transferred more or less energy in the morning than in the afternoon.
Write your answer in complete sentences.
Answer:
They transfered more energy in the morning.
Explanation:
This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with the waves. They have more energy, so they can crash aganst the shore more!

Why was John Paul Jones's victory important in the war? His victory increased France's confidence in the skill of the Continental navy. His victory against a large warship dealt a blow to the Spanish navy. His victory against a superior British foe inspired the American troops.
Answer:
C. His victory against a superior British foe inspired the American troops.
Explanation:
John Paul Jones is considered the hero in the Revolutionary War. He is known as the Father of the US Navy.
In the Revolutionary War, Jones sided with the American colonists against the British and took hold of naval ships. In 1779, when the British warship Serapis was in conflict with the American warship Bon Homme Richard, Jones plugged the American warship with the Britisher's warship and tossed a grenade into the opponent warship. Thus when Jones was victorious in the war, this boosted the American spirits for the war.

the process through which electrons are attracted to or repelled by an external electric field, causing the electrons to move within their own atoms
Answer:
Polarisation
Explanation:
When the electric field of an atom distorts then the cloud of negative charges move away from the clouds of positive charges. This movement of clouds in opposite direction causes separation of charges and and causes one side positive and one side negative. This process is known as polarisation

1. A ball rolls off a 1.0 m high table and lands on the floor, 3.0 m away from the
table.
A. What is the vertical velocity of the ball just before it hits the floor?
d. What is the horizontal velocity of the ball just before it hits the floor
Answer:
5.55m/s
Explanation:
The vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.
Which type of motion is projectile motion?
Projectile motion is an example of two dimensional motion.
Given is a ball rolls off a 1 m high table and lands on the floor 3 m away from the table.
Using the second equation of motion for the vertical motion -
S = ut + 1/2at²
S = 0 + 1/2at²
S = 1/2at²
t²= 2S/a
t² = (2 x 1)/9.8
t² = 2/9.8
t² = 0.2040
t = 0.451
Now, the vertical velocity of the ball just before it hits the floor -
v = u + at
v = 0 + at
v = at
v = 9.8 x 0.451
[v] = 4.42 m/s
Now, using the second equation of motion for horizontal direction -
S = ut + 1/2at²
S = ut + 0
3 = u x 0.451
u = 3/0.451
[u] = 6.6 m/s
Which is also the horizontal velocity of the ball just before it hits the floor.
Therefore, the vertical velocity of the ball just before it hits the floor is [v] = 4.42 m/s and horizontal velocity of the ball just before it hits the floor is [u] = 6.6 m/s.

A train reaches a speed of 35.0 m/s after accelerating at a rate of 5.00 m/s2 over a distance of 40.0 m. What was the train’s initial speed?
Answer:
Initial velocity, U = 28.73m/s
Explanation:
Given the following data;
Final velocity, V = 35m/s
Acceleration, a = 5m/s²
Distance, S = 40m
To find the initial velocity (U), we would use the third equation of motion.
V² = U² + 2aS
Where;
V represents the final velocity measured in meter per seconds.
U represents the initial velocity measured in meter per seconds.
a represents acceleration measured in meters per seconds square.
S represents the displacement measured in meters.
Substituting into the equation, we have;
35² = U + 2*5*40
1225 = U² + 400
U² = 1225 - 400
U² = 825
Taking the square root of both sides, we have;
Initial velocity, U = 28.73m/s

Please write ONE complete sentence describing the relationship between Kinetic Energy and Gravitational Potential Energy in a system
where energy is conserved:
Answer:
Explanation:
The sum of kinetic and potential energy is the mechanical energy of the system. Assuming the energy of the system is conserved, which it is in your case, then the initial mechanical energy will equal the final mechanical energy. This relationship is very useful in mechanics.

Explanation:
A bicyclist steadily speeds up from rest to 11.0m/s during a 5.50s time interval. Determine all unknowns and answer the following questions. What is the magnitude of the bicyclist's acceleration? How far did the bicyclist travel during this time?
Explanation:
acceleration is 2 m/s^2
v-u/t
distance travelled is 30.25 meter
(v^2-u^2)/2a
11*11/2*2
121/4
30.25 m
The acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.
We have a bicyclist.
We have to calculate the acceleration and the total distance travelled by the bicyclist.
State the three equations of motion.The three equations of motion are -
v = u + at
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
v² - u² = 2aS
According to the question -
u = 0 m/s
v = 11 m/s
t = 5.5 s
Therefore -
For acceleration -
v = u + at
On solving -
11 = 0 + 5.5 a
5.5a = 11
a = 11 / 5.5 = 2 m/s²
For total distance covered -
S = ut + [tex]\frac{1}{2}[/tex] a[tex]t^{2}[/tex]
On solving -
S = 0 + 0.5 x 2 x 5.5 x 5.5 = 30.25 meters.
Hence, the acceleration of the bicyclist is 2 m/s² and the total distance covered is 30.25 meters.
