how does a pendulum shows the relationship between gravitational potential energy and kinetic energy and mechanical energy?
Answer:
In a simple pendulum with no friction, mechanical energy is conserved. Total mechanical energy is a combination of kinetic energy and gravitational potential energy. As the pendulum swings back and forth, there is a constant exchange between kinetic energy and gravitational potential energy.
The relationship between the gravitational potential energy and kinetic energy and mechanical energy should be explained below.
Relationship of various energies:In the case of a simple pendulum that does not contain friction, here the mechanical energy should be conserved. The total mechanical energy comprises of kinetic energy and gravitational potential energy. At the time when the pendulum should swing back and forth so there should be a constant exchange that lies between the kinetic energy and gravitational potential energy.

Imagine your teacher asks you to design an experiment where you test the effect of temperature on the growth of a plant. You have 5 plants that you plant and place in different temperatures around the room. What would your variables be and what would your constants be.
pls do it dont do it if u dont know
dont do it for the points
Answer:
the variable would be the temperatuer. and the water u give it would be constant.
Explanation:
the same amount of water go's to all of the plant's . and u cange the variable and your changing the temp .

Student Name Potential Energy Rating (lowest to highest)
Henry gas, liquid, solid
Jasmine gas, solid, liquid
Lucas solid, gas, liquid
Tasha solid, liquid, gas
Four students rank the potential energies of some states of matter. Which student is correct?
(1 point)
Lucas
Jasmine
Tasha
Henry
A substance's potential energy decreases from solid to liquid to gas to plasma in that order. The most potential energy and least kinetic energy would be in the solid state. So, Henry is correct.
What is Potential energy?Potential energy is a type of stored energy that depends on the relative locations of various system components. A spring's potential energy increases when it is stretched or compressed. The potential energy of a steel ball increases as it is raised above the earth's surface as opposed to when it is brought to the planet.
It can perform more work in the raised position. Potential energy is a system property, not a feature of a single entity or particle. For example, the system made up of Earth and the elevated ball has greater potential energy as they are further apart.

We learned that refraction is the bending of light and reflection is the bouncing of light. What do you think diffraction might be?
PLEASE HURRY, I'M TIMED! WILL GIVE BRAINLIEST! PLEASE ANSWER WITH WHAT YOU THINK DIFFRACTION IS!
Answer:
Diffraction of light occurs when a light wave passes by a corner or through an opening or slit that is physically the approximate size of, or even smaller than the light's wavelength
A car in stop-and-go traffic starts at rest, moves forward 12 m in 8.0 s, then comes to rest again. The velocity-versus-time plot for this car is given in the figure. What distance does the car cover in the first 4.0 seconds of its motion?
Answer:
48 meters per second
Explanation:
Distance travelled in a velocity - time - graph is the area under the graph. The distance covered in the first 4 seconds of its motion is 4.8 meters
From the question and the given graph, the following parameters are given:
Total distance travelled S = 12m
The total time = 8 s
The velocity (V) of the car = ?
We can get V by using the area of a trapezium formula. That is,
S = 1/2( a + b )V
Where from the graph;
a = 2 and b = 8
Substitute a, b, and S into the above equation
12 = 1/2( 2 + 8 )V
24 = 10V
V = 24/10
V = 2.4 m/s
The shape of the distance covered in the first 4 seconds in the graph is triangle.
Area of a triangle = 1/2 x base x height
where
Area = distance covered
base = time = 4s
height = speed V = 2.4
The formula can be re-written as:
S = 1/2 x t x V
substitute all the necessary parameters into the above formula
S = 1/2 x 4 x 2.4
S = 4.8 m
Therefore, the distance covered in the first 4 seconds of its motion is 4.8 meters
