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
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
Correct answer: 2.08 x 10⁸m/s
n=c/v
1.44=(3.oo x 10⁸m/s)/v
v=(3.oo x 10⁸m/s)/1 .44
v=2.08 x 10⁸m/s
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.
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 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
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.
Correct answer: Force
Force is defined as a push or a pull on an object.
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.
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
Correct answer: Average velocity
Average velocity is calculated by taking the object's initial and final speeds and averaging them
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
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.
Correct answer: 0 m/s
Because sound waves cannot travel through a vacuum, the speed of sound in a vacuum is 0 m/s.
Correct answer: Acceleration
Acceleration is the rate of change in velocity over a period of time
Correct answer: Project Motion
In Project Motion it is possible for an object to display two types of motion simultaneously.
Correct answer: Scalar Quantity
The Scalar quantity stated in units of magnitude and is described simply by a numeric value.
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).
Correct answer: Velocity
The term "velocity" refers to the speed at which something moves in a given direction.
Correct answer: -4.6 m/s²
ma = F
where
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.
