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.

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

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.

Five facts about wind, currents, and Coriolis effect. Please ensure that these five facts are in complete sentences.
Answer:
wind 1) Wind is the flow of gases, here on Earth it refers to the movement of air.
wind 2) It is caused by differences in air pressure.
wind 3)Short bursts of wind moving at high speeds are known as gusts.
wind 4) Depending on their strength, winds can be known as a breeze, gale, storm or hurricane.
wind 5) Windmills have been in use since 2000 B.C.
currents 1)The continuous flow of ocean currents is a natural effort to bring a horizontal heat balance.
currents 2) Warm currents bring rain to the coastal areas because they supply moisture to the winds.
currents 3)Cold polar currents bring large ice-bergs which are a source of fresh water.
currents 4) Warm currents keep the ports in the polar region operational because it makes an ice-free throughout the year.
currents 5)There are tremendous potentialities of producing power from the ocean currents.
Coriolis 1) Gustave-Gaspard Coriolis, was a French engineer-mathematician.
coriolis 2) In 1835 Coriolis mathematically described this concept.
Coriolis 3)The Coriolis Effect is based on the Laws of Motion discovered by Sir Isaac Newton.
Coriolis 4)Coriolis used mathematical formulas to show that the path of any object set in motion will curve in relation to objects on that surface.
coriolis 5) When it comes to projectile trajectories, terrestrial wind system, and ocean currents, the Coriolis effect is a good concept to account for.

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
