Kara drops a rock from the edge of a cliff and it takes 7.00 s for the rock to reach the ground. What is the cliff’s height?
Answers
Answer:
h = 204.1 m
Explanation:
Given that,
Time taken to reach the ground, t = 7 s
We need to find the height of the cliff. We can find it using second equation of kinematics as follows :
[tex]h=ut+\dfrac{1}{2}at^2[/tex]
Here,
u = 0 (at rest initially)
a = g
So,
[tex]h=\dfrac{1}{2}gt^2\\\\h=\dfrac{1}{2}\times 9.8\times 7^2\\\\h=204.1\ m[/tex]
So, the cliff's height is 204.1 m.

Describe an example of Newton’s 1st Law of Motion (the motion of an object remains the same unless it is acted upon by a force)
Answers
Answer:
if your in a car and you suddenly stop since you were in motion you fling forward while the car is stopped because an object in motion stays in motion unless it's stopped by an outside force and that's why we have seatbelts
Newton’s 1st Law of Motion is the motion of an object remains the same unless it is acted upon by a force.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
If your in a car and you suddenly stop since you were in motion you fling forward while the car is stopped because an object in motion stays in motion unless it's stopped by an outside force and that's why we have seatbelts.

The helium-filled balloons below are carrying negative electric charges, as shown. Attach two of the balloons to the hooks below to show what would happen if a red balloon and a blue balloon were brought near each other. Plzz help
Answers
Answer:
these are in the hooks the balloons repel each other if the hooks are isolated.
Explanation:
In electrostatics, charges of the same sign repel and of a different sign attract each other.
With this explanation we analyze the situation presented, they indicate that the balloons have a negative taste, so when these are in the hooks the balloons repel each other if the hooks are isolated.
If the hooks are connected to Earth, the poop of the balloons is neutralized, so there is neither attraction nor repulsion.

The speed of sound through diamond is about 12,000 m/s. The speed of sound through wood is about 3,300 m/s. Which statement explains why the speed of sound is different through these materials?(1 point)
They have different rigidities.
They have different temperatures.
They have different phases of matter.
They have different salinities.
Answers
Answer: They have different rigidities.
Explanation:
The speed of sound is different through these materials because, they have different rigidities.
What is meant by rigidity of a material ?The property of a material that prevents its shape from changing as a result of an external force is known as rigidity.
Here,
Given that, the speed of sound through diamond is about 12,000 m/s and the speed of sound through wood is about 3,300 m/s.
This is due to the variation in rigidity of the materials through which the sound is travelling.
The stiffness of the medium (or compressibility in the case of gases) and its density work together to define the speed of sound in that medium. The speed of sound increases with the rigidity of the medium. The speed of sound decreases with increasing medium density.
Hence,
The speed of sound is different through these materials because, they have different rigidities.

The recoil of a cannon is probably familiar to anyone who has watched pirate movies. This is a classic problem in momentum conservation. Consider a wheeled, 500 kg cannon firing a 2 kg cannonball horizontally from a ship. The ball leaves the cannon traveling at 200 m/s. At what speed does the cannon recoil as a result?
Answers
Answer:
0.8 m/s
Explanation:
From the question,
MV = mv............................. Equation 1
Where M = mass of the cannon, m = mass of the cannonball, V = velocity of the cannon, v = velocity of the cannon ball.
make V the subject of the equation
V = mv/M........................ Equation 2
Given: m = 2 kg, M = 500 kg, v = 200 m/s
Substitute these value into equation 2
V = (2×200)/500
V = 400/500
V = 0.8 m/s

At which position is the LOWEST potential energy?
Answers
Potential Energy is “stored energy.” It is energy that is ready to be converted or released as another type of energy. We most often think of potential energy as gravitational potential energy. When objects are higher up, they are ready to fall back down. When you stretch an object and it has a tendency to return to its original shape, it is said to have elastic potential energy. Chemical potential energy is the stored energy in a substance’s chemical structure that can be released in a chemical reaction or as heat.
