Answer:
1. Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.
2. Longitudinal waves are waves in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of propagation of the wave.
3. A mechanical wave is a wave that is an oscillation of matter and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.
4. Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second.
5. The amplitude of a periodic variable is a measure of its change in a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values. In older texts, the phase of a period function is sometimes called the amplitude.
6. In physics, mathematics, and related fields, a wave is a propagating dynamic disturbance of one or more quantities, sometimes as described by a wave equation. In physical waves, at least two field quantities in the wave medium are involved.

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.

How is energy different from work (your own words please)
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.

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

Scientists often use containers to hold chemicals. A beaker can hold solids or liquids that won’t release gas and are unlikely to splatter if stirred or heated. A test tube is basically a smaller version of a beaker. It can hold small amounts of chemicals. If you’re worried about a substance splattering, an Erlenmeyer flask might be a good tool to use. Erlenmeyer flasks have a triangular shape to minimize splattering and spilling. To be extra safe about spills, you might use a stopper. However, never heat a container with a stopper on it!
According to the passage, why is a substance in an Erlenmeyer flask less likely to spill than a substance in a beaker?
A
because Erlenmeyer flasks can never be heated
B
because Erlenmeyer flasks can only hold solid substances
C
because Erlenmeyer flasks hold smaller amounts of substances than beakers
D
because Erlenmeyer flasks have a triangular shape
