What is the speed of sound in a vacuum?

Correct! Wrong!

Correct answer: 0 m/s

Because sound waves cannot travel through a vacuum, the speed of sound in a vacuum is 0 m/s.

average speed = d/t 
is the distance an object travels divided by the time it takes to travel in the same direction.

Correct! Wrong!

Correct answer: Velocity

The term "velocity" refers to the speed at which something moves in a given direction.

A ball is kicked off the edge of a 34-meter-high roof. The ball is given a horizontal speed of 12.5 m/s. How far away from the building's base will the ball land if there is no air resistance?

Correct! Wrong!

Correct answer: 32.86 m

Vₓ= (12.5 m/s) horizontal velocity
dᵧ= the object's vertical displacement (34 m)
dₓ = unidentified (this is what we are solving for)
t = unidentified (flight time)
a = 9.8 m/s²
Because no air resistance is assumed, dₓ = Vₓ t.
To solve this problem, we'll apply the distance equation (dₓ = Vₓ t). However, the flight time (t) is not specified in the problem, therefore we must solve for it. The following is the equation to solve for flying time:
√((vertical distance)/(1/2)(vertical acceleration)) = Flight Time
We receive the following results when we plug in our known quantities:
√((34 m)/(1/2)(9.8 m/s²)) = Flight Time
2.63 second flight time
dx = vₓt 
dₓ = 12.5 m/s x 2.63 s 
dₓ = 32.86 m

Kath's car went from 0 to 60 miles per hour in 2.5 seconds. What was the car's rate of acceleration?

Correct! Wrong!

Correct answer: 24 m/s²

Acceleration is defined as a change in velocity over time.
The car accelerates from 0 to 60 m/s, resulting in a velocity change of:
60 m/s minus 0 m/s equals 60 m/s
The car took 2.5 seconds to reach 60 m/s, thus the total time is 2.5 seconds.
These figures are entered into the formula:
60 m/s ÷ 2.5 s = acceleration
24 m/s2 = acceleration

Which of the following statements about a negatively charged particle is correct?

Correct! Wrong!

Correct answer: There are more electrons than protons in it.

Electrons (which have a negative charge) outnumber protons in a negatively charged particle (which have a positive charge).

The acceleration due to gravity on Earth is -9.8 m/s². Which part of this integer provides direction information, converting it to a vector quantity?

Correct! Wrong!

Correct answer: We know it's a vector quantity because the negative sign indicates a downward acceleration.

Direction and magnitude are encoded in vector quantities. The magnitude of a scalar quantity is the sole thing that gives it meaning.

The unit of the quantity is the gravitational acceleration constant for Earth: -9.8 m/s². Because the units of acceleration are length/time2, this indicates that the quantity is acceleration. It also indicates that we are using SI units. We must convert things if an issue delivers amounts in a different metric system.
− (The negative sign) indicates the quantity's direction. The positive symbol + is frequently omitted when the value is positive. We know the quantity is a vector because of its name and context. On Earth, gravity drags us to the surface. As a result, we know that the gravitational acceleration constant has a negative sign, indicating that gravity is downward.

On the ice, a hockey puck comes to a slow stop. The puck has a mass of 0.5 kg and a friction force of 2.3 N between it and the ice. What is the puck's rate of acceleration?

Correct! Wrong!

Correct answer: -4.6 m/s²

ma = F
F stands for Force.
m stands for mass (in kg)
a = rate of change (in m/s²)
To determine an object's acceleration, we must first isolate acceleration. We do it by dividing both sides by the mass:
ma = f
ma/m = f/m
a = F/m
4.6 m/s2 = 2.3 N / 0.5 kg
Because the puck is slowing down, we know this force is negative.

The quantity  stated in units of magnitude and is described simply by a numeric value.

Correct! Wrong!

Correct answer: Scalar Quantity

The Scalar quantity  stated in units of magnitude and is described simply by a numeric value.

The refractive index of chloroform is 1.44. In this medium, what is the speed of light?

Correct! Wrong!

Correct answer: 2.08 x 10⁸m/s

1.44=(3.oo x 10⁸m/s)/v
v=(3.oo x 10⁸m/s)/1 .44
v=2.08 x 10⁸m/s

A human weighs 76 kg. What is this person's weight on the earth?

Correct! Wrong!

Correct answer: 745 N

Weight = milligrams
The person's weight is 76 kilograms.
Earth's gravitational constant is 9.8 m/s².
Weight = 76 kg x 9.8 m/s² = 744.8 N = 745 N

What is the frequency of a wave in a string that moves at 52 m/s and has a wavelength of 0.65 m?

Correct! Wrong!

Correct answer: 80 Hz

Frequency is equal to the product of speed and wavelength.
frequency = 52 m/s / 0.65 m
80 Hz is the frequency.

A quantity that describes the rate at which an object's position changes over time and must be represented in both magnitude and direction of motion.

Correct! Wrong!

Correct answer: Vector quantity

Vector quantity is a quantity describing the time rate of change of an object's position and must be expressed in both units of magnitude and direction of motion.

According to the same-name theory, there were only two things left after the "Big Bang"?

Correct! Wrong!

Correct answer: antimatter and matter

The Big Bang Theory tries to explain how the universe came to be. According to the theory, a "big bang" produced equal amounts of matter and antimatter.

Jessa drives her car for 15 minutes at an average speed of 35 mph. What was the length of her journey?

Correct! Wrong!

Correct answer: 8.75 miles

Distance traveled divided by time equals average speed.
(Average Speed) x (time) = (Distance Traveled) 
The average speed is 35 miles per hour.
15 minutes divided by 60 minutes equals 1/4 hour
Distance traveled = (35 mph)(1/4 hours) = 8.75 miles

A baseball weighing 0.125 kg is thrown at 40.1 meters per second. What is the ball's Kinetic Energy?

Correct! Wrong!

Correct answer: 101 J

½  x mv² = KE
KE stands for kinetic energy (measured in Joules – J).
m stands for mass (expressed in kilograms)
v² stands for velocity (expressed in meters per second squared)
1/2 x mv²= KE

v = 40.1 m/s
v = 40.1 m/s
KE = 1/2 x (0.125 kg) x (40.1 m/s)² = 100.5 J, or 101 J rounded up.

Correct! Wrong!

Correct answer: Average velocity

Average velocity is calculated by taking the object's initial and final speeds and averaging them

the rate at which a vehicle's velocity changes over time

Correct! Wrong!

Correct answer: Acceleration

Acceleration is the rate of change in velocity over a period of time

Unless operated on by an imbalanced force, the body at rest will remain at rest, and the body in motion will remain in motion with a constant velocity; F=ka

Correct! Wrong!

Correct answer: Newton's First Law of Motion

Newton's First Law of Motion states that the body at rest will remain at rest, and the body in motion will remain in motion with a constant velocity, unless acted on by an unbalanced force; F=ka
