Answer:
5 912 500 000 000 = 5.91x10^12 miles
Explanation:
The first thing we need to do is convert the light year distance to kilometres, since we have the kilometre to mile conversion. There are 1000m in a kilometre, so we need to divide the light year value that we have by 1000, giving us 9.46x10^12 km for 1 light year.
Now that we have our value in kilometres, we simply need to divide it by 1.6 to get it in miles. Doing so gives us 5 912 500 000 000 miles, or 5.91x10^12 miles.
Hope that made sense, and let me know if you have any further questions!

A baseball pitcher throws a fastball at a speed of 44 m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it through an almost straight-line distance of 3.5 m. Calculate the acceleration, assuming it is uniform. Compare this acceleration to the acceleration due to gravity.
v = s/t
44 m/s = 3.5 m/t
t = 3.5 m : 44 m/s
t = 0.08 s
a = v/t
a = 44 m/s/0.08 s
a = 550 m/s²
a : g = 550 m/s² : 10 m/s²
a : g = 55 : 1

Find out which of the following sentences is a false statement. Group of answer choices The potential energy of a pair of positively charged bodies is positive. The potential energy of a pair of oppositely charged bodies is negative. The total work required to assemble a collection of discrete charges is the electrostatic potential energy of the system. The potential energy of a pair of negatively charged bodies is negative. The potential energy of a pair of oppositely charged bodies is positive.
The statements which are false from the choices above are:
The potential energy of a pair of negatively charged bodies is negativeThe potential energy of a pair of oppositely charged bodies is positiveIn scenarios of like charges, the potential energy is always positive, that is because we need to put energy in the system to bring like charges closer together.
Conversely, for unlike charges, the potential energy of the pair of unlike charges is negative, as a result of the energy expended by the system in pushing the charges away from each other.

A 5.7 kg block slides along a horizontal surface toward a horizontally mounted spring with a spring constant of 150 N/m. At one instant, the block is 5.0 m from the end of the spring and has a speed of 12.0 m/s. If the surface is frictionless, what is the maximum compression of the spring
Hi there!
We can use the conservation of energy:
Ei = Ef
The initial energy involves kinetic energy while the final energy involves maximum elastic potential energy, so:
1/2mv² = 1/2kx²
We can cancel out the 1/2s for ease of solving:
mv² = kx²
Plug in given values to solve for x:
√(mv²/k) = x
√(5.7)(12²)/(150)) = x
x = 2.339 m
London lives 1200 meters south of Chick-fil-A and is thinking about going there for lunch. When she is ready to leave, she realizes she left her wallet at her Aunt's house. She walks 750 meters to her aunt's house and then 1000 meters to Chick-fil-A. It took her 30 minutes to get from her house to Chick-fil-A. What was her distance traveled?
Answer:
1750 m
Explanation:
The distance traveled is the 750 meters to the Aunt's house plus the 1000 m from there to Chick-fil-A.
750 +1000 = 1750 . . . meters traveled
The weight of an object is 180 N at a distance of 150 km above a planet's center. What is the weight of the object when it moves 450 km above the center of the planet?
By using Newton law of gravitation, the weight of the object when it moves 450 km above the center of the planet is 20N
Given that the weight of an object is 180 N at a distance of 150 km above a planet's center.
F = GMm/[tex]r^{2}[/tex]
F = mg = 180N
r = 150
When it moves 450 km above the center of the planet, G, M and m will be constant. only r will vary.
180 = GMm/[tex]150^{2}[/tex]
Make GMm the subject of the formula
GMm = 180 x 22500
GMm = 4050000
As it moves 450 km above the center of the planet, Its weight will be
F = GMm/[tex]r^{2}[/tex]
Substitute all the values and parameters
F = 4050000/[tex]450^{2}[/tex]
F = 20 N
Therefore, the weight of the object When it moves 450 km above the center of the planet is 20 Newtons

Please complete the following:
You and Tim, who is larger than you, are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon when it had the greatest acceleration during start up? Why? Use Newton’s second law to explain.
Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton’s second law.
Answer:
First scenario,
From 2nd Newton's law
F = ma
from the above eqn, it's evident
a = F/m
that is to say, acceleration is inversely proportional to mass
The greater the mass, the smaller the acceleration and the higher the acceleration, the smaller the mass.
Thus, You was in the wagon when it had the greatest acceleration because You has the smaller mass and thus the acceleration will be greater.
Second scenario,
Since Sara pulls with greater force and Force is directly proportional to acceleration according to the second Newton's law,
F = ma
then, when You is in the wagon it had greater acceleration since they have the same mass.
All the best!

A driver spotted a police car and he braked from a speed of 100 km/h to a speed of 80 km/h during a displacement of 88 m at a constant acceleration? What is that acceleration, and how much time is required for the given decrease in speed?
Answer:
Explanation:
100 kph = 27.8 m/s
80 kph = 22.2 m/s
v² = u² + 2as
a = (v² - u²) / 2s
a = (22.2² - 27.8²) / (2(88))
a = -1.578282828...
a = -1.58 m/s²
t negative sign means the acceleration opposes the initial velocity.
t = Δv/a
t = (22.2 - 27.8) / -1.57828
t = 3.52 s
What is Juan’s velocity between 0-5 seconds?
Juan’s velocity between 0-5 seconds would be 2 m/s, the slope of the position time graph represents the velocity of the object and between the 0-5 seconds slope of the line is 2.
What is Velocity?The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.
velocity= total displacement/Total time
As given in the problem we have to find the velocity of Juan between 0-5 seconds.
The displacement covered between 0-5 seconds is 10 meters.
the time taken to change position is 5 seconds,
the velocity of the Juan = 10/5
= 2 meters/seconds
Thus, its velocity of Juan comes out to be 2 meters/second.

The Ojibwe protected walleye populations as D. They said a limit on the number and size of Walleye a spearfisher can catch.
Wisconsin Walleye War was a series of protests regarding the fishing and hunting rights of the Ojibwes. Wisconsin wanted to regulate the rights of the people whenever they went fishing and hunting.
The protest eventually led to the state speaking to the people. This resulted in a resolution that there should be a limit on the number and size of Walleye a spearfisher can catch.
This was necessary in order to preserve the walleye for future generations.

A)If the vehicle has a speed of 18.0 m/s at point a, what is the force (in N) of the track on the vehicle at this point?
B) What is the maximum speed (in m/s) the vehicle can have at point B in order for gravity to hold it on the track?
Point A says the radius is 10m. Point B says radius is 15m.
Answer:
Explanation:
I'm going to ASSUME that point A is at the bottom of a circular curve.
The track must support the weight of the car and also supply the needed centripetal force
F = mg + mv²/R
F = 585(9.81 + 18.0²/10) = 24,692.85
F = 24.7 kN
I'm going to ASSUME that point B is at the top of a circular curve.
The track must support the weight of the car and also supply the needed centripetal force.
At a minimum, the weight can be reduced to zero and all the gravity acceleration acts as centripetal acceleration.
0 = mg - mv²/R
g = v²/R
v = √Rg = √(15(9.81) = 12.1305399...
v = 12.1 m/s
