The potential energy that depends on height is called gravitational potential energy. (Option B)
What is gravitational potential energy?Gravitational potential energy is a form of potential energy that an object possesses due to its position relative to a gravitational field.
When an object is raised to a certain height above the ground, it gains gravitational potential energy. The higher the object is raised, the greater its potential energy.
This potential energy is a measure of the work that would be required to move the object against gravity and bring it back down to its original position.
The formula for gravitational potential energy is;
Potential Energy (PE) = mg h

Three toy boats with the same mass were in a lake. Two boats were moving and one was stopped. Each boat got bumped by another boat, but not in the same direction. All the boats changed speed as a result of being bumped. Use the information in the diagram to answer. Which toy boat exprienced the strongest force when it was bumped ? How do you know ?
The answer is " The orange and gray toy boats experienced the strongest force because both gained the same force as they sped up the blue boat lost force so it slow down
Explanation:
Trust me I did this one for an assignment
The boat that will experience the strongest force is the boat that has the highest speed.
According to Newton's second law of motion, the force applied to an object is directly proportional to the product of mass and acceleration of the object.
F = ma
[tex]F = \frac{mv}{t}[/tex]
where;
F is the force experienced by the objectv is the velocity of the objectt is the time of motionThe force experienced by the boats is directly proportional to the velocity of their motion. Since the boats have the same mass, the force experienced by each boat will depend on the speed with which the boat moves.
Thus, the boat that will experience the strongest force is the boat that has the highest speed.

For the first 10 seconds a squirrel runs 3 m/s to look for an acorn. The next 5 seconds he eats an acorn that he finds. Afterwards the squirrel runs 2 m/s back to where he started. (A) How long does it take for the squirrel to get back to where he started?
Distance covered by the squirrel to look for an acorn :
d = ( 3 m/s ) × 10 s = 30 m.
Time taken to eat an Acron is 5 seconds.
Time taken to cover distance of 30 m with 2 m/s speed is :
[tex]T=\dfrac{30}{2}\ s= 15 \ s[/tex]
Therefore, total time take to get back to where he started is ( 10+5+15 ) = 30 s.
Hence, this is the required solution.

The radius of Mars is 3.4 x 10^6m and the period of Mars's rotation is 24 hours. What is the radial accelerations (in m/s^2) of an object on the ground at its equator?
A. 0.018m/s^2
B. 0.136m/s^2
C. 0.068m/s^2
D. 0.376m/s^2
Answer:
Option A: 0.018m/s^2
Explanation:
Formula for radial acceleration is;
α_r = ω²r
Now, ω = 2π/T
We're given T = 24 hours. Converting to seconds is; T = 24 × 60 × 60 seconds
ω = 2π/(24 × 60 × 60)
We are given radius = 3.4 × 10^(6) m
Thus;
α_r = (2π/(24 × 60 × 60))² × 3.4 × 10^(6)
α_r = 0.018 m/s²

A driver of a car traveling at -15m/s applies the brakes, causing a uniform acceleration of +2.0m/s2. If the brakes are applied for 2.5s, what is the velocity of the car at the end of the braking period? How far has the car moved during the braking period?
Given :
Initial velocity, u = -15 m/s.
Acceleration , a = 2 m/s².
Time taken to applied brake, t = 2.5 s.
To Find :
The velocity of the car at the end of the braking period.
How far has the car moved during the braking period.
Solution :
By equation :
[tex]v = u+at\\\\v=-15 + 2\times 2.5\\\\v=-10 \ m/s[/tex]
Now, distance covered by car is :
[tex]s=ut+\dfrac{at^2}{2}\\\\s=(-15)(2.5)+\dfrac{2(2.5)^2}{2}\\\\s=-31.25\ m[/tex]
Hence, this is the required solution.
A 20 N model rocket launched vertically is clocked at 25 m/s when it is 15 m above the ground (and has expended a negligible amount of fuel). Use the work–energy principle to find the rocket’s initial speed.

Explanation:
Determine the weight of a 2959.0-kg car that is moving at a speed of 21 m/s. Enter a
numerical answer.
weight=mass*gravity
w=2959.0*10
w=29590N
The weight of a 2959.0-kg car that is moving at a speed of 21 m / s would be 28998.2 Newtons, here speed of the car is the redundant value that is not used to calculate the weight of the car.
What is gravity?It can be defined as the force by which a body attracts another body toward its center as the result of the gravitational pull of one body and another.
As given in the problem, we have to determine the weight of a 2959.0-kg car that is moving at a speed of 21 m / s .
The weight of the car = mass of the car × acceleration due to gravity
= 2959 × 9.8
= 28998.2 Newtons
Thus, the weight of a 2959.0-kg car that is moving at a speed of 21 m / s would be 28998.2 Newtons.

Complete Question
An astronaut stands by the rim of a crater on the moon, where the acceleration of gravity is 1.62 m/s2. To determine the depth of the crater, she drops a rock and measures the time it takes for it
to hit the bottom. If the time is 6.3 s, what is the depth of the crater?
Answer:
The depth is 32 m
Explanation:
From the question we are told that
The time is t = 6.3 s
The acceleration due to gravity is [tex]g = 1.62 \ m/s^2[/tex]
Generally from kinematic equation
[tex]s = ut + \frac{1}{2} - at^2[/tex]
Here the u is the initial velocity and the value is 0 m/s
[tex]s = 0 + \frac{1}{2} - (1.62) * (6.3)^2[/tex]
[tex]s = 32 \ m [/tex]

O the illuminated opaque object and the umbra
Answer:
the umbra and penumbra
Explanation:
The two parts of a shadow are the umbra and penumbra.
A shadow is an expression formed when light from a source is cut blocked by an opaque body.
Most shadows are made up of two parts, umbra and penumbra.
The umbra is the darkest, and the innermost part of a shadow. In the penumbra, only a portion of the light source is blocked. It is more of like a partial shadow.The umbra is directly formed by light which impinges on an opaque body and it completely cut off.
You and your friends are going on a picnic in a very small car. On your way, the car breaks down and you try to push it to get it to move but in vain. You ask your friends to help you and the car starts moving and revs up. How are you and your friends applying Newton's second law of motion here? What if the car you were traveling in was a large SUV?
Answer:
The pushing of the car by you and your friends is the applied force and when the car moves, it means that the velocity has changed thus causing the movement or acceleration.
Explanation:
Newton's work on forces regarding motion can never be neglected by scientists. Sir Isaac Newton when he was alive, among several of his works he proposed the three laws guiding the forces of motion. In this question we are only going to be treating only one out of the three Newton's Law of motion and that is the second Law Of Newton's laws of motion.
The second Law Of Newton's laws of motion states that the acceleration of an object is directly proportional to the applied force and inversely proportional to the object's mass.
(1). Now, to the question: " How are you and your friends applying Newton's second law of motion here? "
The pushing of the car by you and your friends is the applied force and when the car moves, it means that the velocity has changed thus causing the movement or acceleration.
According to the law, the more the Force, the more the acceleration.
(2). For the second part of the question, " What if the car you were traveling in was a large SUV?"
From the law stated above we see that the acceleration is inversely proportional to the mass, thus if the car is a large SUV, It means that more force is needed to change the car's velocity.
Answer:
When a friend joins you in pushing the small car, the net force on it increases. Therefore, it starts to move. The mass of a SUV is much greater than that of a small car. You would thus need the help of more friends to help push it.

Coulomb's law describes how the charge on and distance between two
particles affect the electric force between them. Which situation will result in
the two particles being attracted to each other?
The situation in which one particle has a positive charge and one has a negative charge will result in the two particles being attracted to each other.
What is Coulomb's law?It states that the force between two charged particles is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between them.
Given is Coulomb's law which describes how the charge on and distance between two particles affect the electric force between them.
From the properties of charges, we know that the like charges repel and unlike charges attract each other. This means that two positive charges will repel each other and two negative charges will also repel each other. However, if one positive and one negative charge are brought closer to one another, than they will attract each other.
Therefore, the situation in which one particle has a positive charge and one has a negative charge will result in the two particles being attracted to each other.
