Planets A and B have the same size, mass, and direction of travel, but planet A is traveling through space at half the speed of planet B. Which statement correctly explains the weight you would experience on each planet?
Planet A is heavier than Planet B
Because Planet A is heavier than Planet B, Planet B will be easier to be moved by gravity causing it to move faster than Planet A.

You are reviewing your results from an experiment involving a soccer ball being kicked. You claimed that, "unbalanced
forces were exerted on the soccer ball, causing the ball to move and also eventually stop." Please support the best
justification that supports your claim.
А
When I kicked the ball, the ball moved in the direction that my
leg was kicking it. This is because when my foot hit the ball my
force overcame the gravity holding the ball down. Gravity
eventually pushed the ball back down but only after I scored a
goall!
My foot applied an unbalanced force to the ball. I knew this
happened because the ball sitting still meant the forces were
balanced and only unbalanced forces can cause a ball to move.
The ball went 30ft in 5 seconds, so it's speed was 6m/s.
When I kicked the ball, I was applying an unbalanced force.
This force accelerated the ball away from me and because the
ball accelerated I know my force was unbalanced. As the ball
traveled through the air, air resistance caused the ball to slow
down, gravity pulled it back down, and rolling friction on the
ground caused it to stop
Newton's first law said that the ball would sit still until
something acted on it, so I acted on it. Newton's second law
made the ball move forward because it has a small mass. And
Newton's third law explains why the ball hit me back when I
kicked it. Sliding friction eventually made the ball stop,

About how long does it take Earth to complete one revolution around the Sun?
1 year
14 days
24 hours
27.3 days
Answer:
1 year = 365 days
because Earth Revolution is the movement of the Earth around the Sun
The earth takes 1 year or 365 days to complete one revolution around the sun. Thus option A is correct.
What is the rotation and revolution of Earth?Rotation and revolution refer to the circular motion of the objects. Rotation is defined as the circular motion of the object about its own axis whereas revolution refers to the circular motion around the other object.
The Earth rotates around its own axis which is called Earth's rotation. The Earth takes 24 hours to rotate on its own axis and the Earth's rotation causes day and night on Earth.
The earth revolves around the Sun which is called Earth's revolution. The Earth takes 365 days to complete one revolution around the Sun and the 365 days is calculated as 1 year. The full revolution of Earth is responsible for climate and seasonal change.
Combined spinning and revolution of Earth lead to changes in daily weather and global climate conditions by affecting wind directions, temperature, and ocean currents, etc.
Thus the Earth takes 1 year to complete one revolution around the Sun. Hence, the ideal solution is Option A.

There is a 90 kg woman attached at the end of a bungee cord (k = 35 N/m) that is experiencing simple harmonic motion. How long does it take the woman to complete one cycle?
Answer:
The value is [tex]T =10.1 \ s[/tex]
Explanation:
From the question we are told that
The mass of the woman is [tex]m = 90 \ kg[/tex]
The spring constant of the bungee cord is [tex]k = 35 \ N/ m[/tex]
Generally the period of the oscillation (i,e time taken to complete on cycle ) is mathematically represented as
[tex]T = 2 \pi * \sqrt{ \frac{m}{k} }[/tex]
=> [tex]T = 2 * 3.142 * \sqrt{ \frac{90 }{ 35} }[/tex]

A student heats a liquid on a burner. What happens to the portion of liquid that first begins to warm? It loses energy. It becomes less dense. It sinks downward. Its molecules get closer together.
PLEASE HURRY
Answer:
they get closer together
A student heats up a liquid on a burner. The portion of liquid which first begins to warm and becomes less dense. Thus, the correct option is B.
When the heat is supplied to the liquid solution through the burner then, a portion of the liquid at the bottom of the solution will start to heat first. This means that the molecules at the bottom of the container will start to gain kinetic energy and thus the intermolecular forces between them start to decrease and they start moving.
As a result of this, the molecules will start to move from their initial position in the solution. That is, the molecules per unit volume of the solution will decrease. Hence, the density of the solution will decrease and the liquid will rise upward.
Therefore, the correct option is B.

the postion-time graph describes the motion of a moving object. Describe the motion represented by each segment of the graph
Answer:
A to B is in constant speed. b to c is speeding up. c to d is not moving. d to e is slowing down.
Explanation:
a to b is at a constant rate of acceleration. (It is speed up but it is doing it consistantly) The line is curving upwards means it is speeding up just not consistantly like a to b. c to d is not going up or down which means it is not in motion. d to e is slowing down because the line curvs down ward.
A to B is at a constant pace. b to c is rushing up. c to d isn't always transferring. d to e is slowing down.

A block of mass 4 kilograms is initially moving at 5m/s on a horizontal surface. There is friction between the block and the surface which causes the block to come to a complete stop. The coefficient of kinetic friction between the block and the surface is 0.5.
Calculate the distance the block slides while coming to a stop. Show all work.
• Net vertical force on the block:
∑ F = n - w = 0
(n = magnitude of normal force, w = weight)
n = w = m g
(m = mass, g = 9.8 m/s²)
n = (4 kg) (9.8 m/s²) = 39.2 N
• Net horizontal force:
∑ F = -f = m a
(f = mag. of friction, a = acceleration)
We have f = µ n = 0.5 (39.2 N) = 19.6 N, so
-19.6 N = (4 kg) a
a = -4.9 m/s²
With this acceleration, the block comes to a rest from an initial speed of 5 m/s, so that it travels a distance ∆x in this time such that
0² - (5 m/s)² = 2 (-4.9 m/s²) ∆x
∆x = (25 m²/s²) / (9.8 m/s²) ≈ 2.55 m ≈ 2.6 m
A 60 kg mass is moving at 5 m/s and collides with a 2 kg mass. All the momentum of the first mass is transferred in the collision to the second mass. What will the velocity (in m/s) be for the 2 kg mass?
Answer:
v = 150 [m/s]
Explanation:
Linear momentum is defined as the product of mass by Velocity. In this way, by means of the following equation, we can calculate the momentum.
[tex]P=m*v\\[/tex]
where:
m = mass [kg]
v = velocity [m/s]
[tex]P =60*5\\P =300 [kg*m/s][/tex]
Since all momentum is transferred, we can say that this momentum is equal for the mass of 2 [kg]. In this way, we can determine the speed after the impact.
[tex]v = P/m\\v = 300/2\\\\v = 150 [m/s][/tex]
2.2 Trigonometry and Vector Components
Answer:
Please find the answer in the explanation
Explanation:
1.) Beta = 180 - ( 90 + 36.9 )
Beta = 180 - 126.9
Beta = 53.1 degree
X and Y can be calculated by using trigonometry ratio ( SohCahToa)
Sin 36.9 = Y /65
Y = 65Sin36.9
Y = 39
Cos 36.9 = X/65
X = 65Cos 36.9
X = 51.97
X = 52 approximately
2.) Using trigonometry ratio again
Tan alpha = 35/60.6
Alpha = tan^-1(0. 577)
Alpha = 30 degree
To calculate beta,
Beta = 180 - ( 30 + 90)
Beta = 180 - 120
Beta = 60 degree
Sin 30 = 35 / R
R = 35/ sin30
R = 35/ 0.5
R = 70
3.) Cos Alpha = 45/47.9
Alpha = cos^-1 ( 0.93945)
Alpha = 20 degree
Beta = 180 - ( 20 + 90)
Beta = 180 - 110
Beta = 70 degree
Sin 20 = Y / 47.9
Y = 47.9sin20
Y = 16.1

You (50 kg) are standing on a skateboard when your friend throws a 5 kg ball at 10 m/s towards your head. You catch the ball to save your face. Describe your motion after you catch the ball, use numbers.
Answer:
v₁ = 1 [m/s].
Explanation:
This problem can be solved by using the principle of conservation of linear momentum. Where momentum is conserved before and after catching the snowball.
[tex]P=m*v[/tex]
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
[tex]P=m*v\\P=5*10\\P=50[m/s][/tex]
As the momentum is conserved, it will be the same as that received by the person who catches the snowball.
[tex]50= 50*v_{1}\\v_{1}=1[m/s][/tex]
That is, the person who catches the snowball moves backwards with a speed of 1 [m/s].
