For every action, there is an equal and opposite reaction” is a definition of _________
Answer:
These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Answer: action, opposite

Explain how sound travels from your vocal cords to your friend’s ear when you talk
Answer:
Your vocal cords vibrate and then travel through the air to your friends ear. ... loudness is a humans perception of sound intensity, as intensity of a sound wave increases the loudness of a sound wave increases.
~+lil more info+~
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear.

Explanation:
A student pulls horizontally on a block with a spring scale. The block reads 24.5 Newtons before the block starts to move. It reads 23.7 Newtons as she pulls the block at a constant velocity. How should she explain this?
Answer:
The coefficient of friction causes the force on the object to be less than its initial reading on the spring scale.
Explanation:
Since the block reads 24.5 N before the block starts to move, this is its weight. Now, when the block starts to move at a constant velocity, it experiences a frictional force which is equal to the force with which the student pulls.
Now, since the velocity is constant so, there is no acceleration and thus, the net force is zero.
Let F = force applied and f = frictional force = μN = μW where μ = coefficient of friction and N = normal force. The normal force also equals the weight of the object W.
Now, since F - f = ma and a = 0 where a = acceleration and m = mass of block,
F - f = m(0) = 0
F - f = 0
F = f
Since the force applied equals the frictional force, we have that
F = μW and F = 23.7 N and W = 24.5 N
So, 23.7 N = μ(24.5 N)
μ = 23.7 N/24.5 N
μ = 0.97
Since μ = 0.97 < 1, the coefficient of friction causes the force on the object to be less than its initial reading on the spring scale.
Is it true that acceleration occurs when there is a change in speed
Answer:
Acceleration is the rate of change of velocity.
Explanation: For example, acceleration is measured in m/2^2 or meters per second squared. That can also be split up into 2 components. M/s is how speed is measured, and since acceleration is the rate of change of velocity, m/(s*s). You could say that since acceleration is m/s^2, it can also be represented as how much the speed increases over 1 second. if there was an acceleration of 3 m/s^2, the rate of change of speed would be 3m/s every second, meaning that the object would speed up 3m/s every second that passes by.
Hope this helps!
A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?
Answer:
200 N
Explanation:
There is only two needed factors in play here; the mass and acceleration
According to Newton's 2nd Law: F = m*a
Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2
Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons

Answer:
Acceleration & 9.8 M/S/S
Explanation:
Pretty self explanatory for question 2, speeding up can easily be related to acceleration, and for question 3
"Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth's surface."

In the acceleration versus time graph above, what is the change in
velocity from 0 to 2s?
Hello!
[tex]\large\boxed{4 m/s}[/tex]
Find the change in velocity by finding the area under the line in an acceleration v. time graph:
We can divide the area underneath the interval 1 - 2 seconds into a rectangle and a triangle. Use the formulas:
A = l × w
A = 1/2(b · h)
We can solve for the rectangle first:
A = 2 × 1 = 2
Do the remaining area using the formula for a triangle:
A = 1/2 (2 · 2) = 2
Add the areas together:
2 + 2 = 4 m/s.
The Δv (change in velocity) is 4 m/s.

A weightlifter completes a series of lifts with a 700 N weight. In one lift, he raises the weight to a height of 2.5 m off the ground. The lift takes 0.60 s to complete. What power does the weightlifter have been performing this lift
Answer:
The output power the weightlifter is 2916.67 W.
Explanation:
Given;
weight lifted, W = 700 N
height the weight is lifted, h = 2.5 m
time taken to lift the weight, t = 0.60 s
The output power the weightlifter is calculated as;
Power = Energy applied / time taken
Energy applied = weight lifted x height the weight is lifted
Energy applied = 700 x 2.5
Energy applied = 1750 J
Power = 1750 / 0.6
Power = 2916.67 J/s = 2916.67 W.
Therefore, the output power the weightlifter is 2916.67 W.
Robbie leaves his house and drives 5 miles North to the post office, 8 miles East to the park, 5 miles South to the grocery store, and then 8 miles West to get back home. What is Robbie's displacement?
Answer:
Robbie's displacement is zero.
Explanation:
Displacement is called the change in position that a body experiences, from an initial point A, to an end point B, through movement. That is, displacement is understood as the length and direction that a body travels to move from an initial point to an end point. Displacement is a vector type quantity, which is described from the magnitude and the direction.
Only the start point and the end point are important for displacement. When the object ends at the same starting point, the displacement will be zero.
You know that Robbie leaves his house and drives 5 miles North to the post office, 8 miles East to the park, 5 miles South to the grocery store, and then 8 miles West to get back home.
Since in this case the start point and end point is Robbie's house, then the offset will be zero.
Which of the following units are the Standard International units for
displacement?
A. Meters (m)
B. Meters per Second (m/s)
C.Meters per Second Squared (m/s2)
D. Seconds per Meter (s/m)

1. why is weathering an exogenic process?
2. state two factors that cause weathering.
Answer:
1. Weathering is the general term applied to the combined action of all processes that cause rock to disintegrate physically and decompose chemically because of exposure near the Earth's surface through the elements of “weather” such as temperature, rainfall, frost, fog and ice.
2. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.

A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground. The correct option is D.
What is projectile motion?Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.
Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.
Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.

A duck is floating in a pond. How does Archimedes' description of the buoyant force explain why the duck
doesn't sink?
PLEASE HURRY
Answer:
The upthrust or buoyant force helps the duck doesn't sink.
For example, there is a duck which weighs 3 pounds and tree pints of water also weigh three pounds. In this case the volume of the duck is more than the volume of three pints of water, so the duck floats.
