Answer and Explanation:
They are both correct.
This is because potential energy is when there is potential for the object to have energy, while kinetic energy is energy that is moving already.
So, as the ball falls, it loses its potential energy, or "still/Stalled" energy, and gains kinetic energy, or moving energy.

From this data, how many male, female, adult, and baby mountain goats do you predict are in the park?
Answer:
80
Explanation:
I literally just did this question lol I hope I helped
In an ecosystem having a park, from the given data there are 71 male,93 female, 103 adults and 61 baby goats in the park.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Which of the following correctly describes how particular type of mirror reflects light? Convex mirrors reflect light to a central point (converging). Concave mirrors reflect light to a central point (converging). Concave mirrors reflect light so the light spreads out (diverging).
Answer:
Concave mirrors reflect light to a central point (converging)
Suppose the source is to the left of the mirror in question.
Parallel rays into the mirror are always reflected towards the focal point.
In the case of a concave mirror the real parallel rays pass thru the focal point.
If the mirror is convex the rays will diverge to the left and act as if they were emanating from the focal point to the right of the mirror.

Alisa, a skateboarder, is riding down a hill. If Alisa and the skateboard are considered a single object, what forces are acting on her? Check all that apply.
Answer: gravity
normal force
friction
Explanation:
A force is refered to as the interaction which when unopposed, will lead to a change in an objects motion. The velocity of an object will be changed when force is applied.
Since Alisa s riding down a hill and she and the skateboard are considered to be a single object, then the forces that are acting on her include gravity, normal force and friction.

Three balls with different masses are shown below.
(picture of beach ball) - 85g
(picture of football) 425g
(picture of baseball) - 149g
If the same amount of kicking force is applied to each ball, which will travel the farthest?
F - They will all travel the same distance because the applied force is the same
G - the baseball because it's the smallest
H - The football because it has the highest mass and was designed for kicking
J - the beach ball because it has the lowest mass
(btw it's a football, not soccer ball)
Answer:
$10 a g
Explanation:
Answer:
As The mass of the beach ball is having lowest magnitude when compared with the other balls given so when apply the same magnitude of force to all the balls then the beach ball due to its lighternessand also its inertia of rest would not resist the force so much so when you apply the force to this ball it would starts to roll and covers the maximum diatance whwn compared with the other ball only in the condition when same magnitude of force applied.Thats this ball would do more work than the other ball.The mass also influences the velocity carried by the body and also the kinetic energy possessed by the body. More the force applied more the distance it would cover

explain why temperature first increases, then begins to decrease throughout the day
Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases.

is the outer electron in potassium more or less strongly attracted to the positive nucleus than the outer electron in sodium is?
Answer:
Less strongly attracted.
Explanation:
Potassium and sodium are both alkali metals. That means that they have the ability to be able to gather more valence electrons. They will both gain a positive particle. The potassium electron is less attracted because of the fact that now the sodium has a positive chargem and the electron has a negative charge.
Some giant ocean waves have a wavelength of 25 m and a frequency of
0.26 Hz. What is the wavespeed of such a wave? *
Answer:
Explanation:
The frequency equation for waves is
[tex]f=\frac{v}{\lambda}[/tex] where f is the frequency, v is the velocity, and lambda is the wavelength. Filling in:
[tex].26=\frac{v}{25}[/tex] so
v = .26(25) and
v = 6.5 meters/second

1. A person walks 50 meters north, and then travels 150 meters to the south. What is the total distance they travelled? What is their displacement from their starting position?
Please help ASAP
Answer:
Total: 200 meters, Displacement: 100 meters South
Explanation:
First, add up the meters traveled to get the total distance.
50m + 150m = 200m
Lastly, displacement is the shortest distance from the initial position to the final position. The person first walked 50 meters north but then traveled 150 meters south. Therefore, their displacement was 100 meters south.
50m - 150m = -100m
(Note: Directions are vectors. North and East are positive vectors while South and West are negative)

Which option best describes the increase in pressure when the volume of a plastic bottle decreases?
by a factor of 10
uneven
uniform
not at all
Answer:
B) uniform
Explanation:
We can solve this problem by using Boyle's law, which states that:
For a constant mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume.
Mathematically:
where
p is the pressure of the gas
V is its volume
If we apply the equation to the bottle in the problem, we see that:
- when the volume of the bottle (and therefore, of the gas inside) decreases, than the pressure will increase
- viceversa, when the volume of the bottle increases, the pressure will decrease
The amount by which the pressure increases is inversely proportional to the decrease in volume, so the answer depends on how the volume of the bottle decreases: however, if the volume of the bottle decreases uniformly, then we can say that the pressure inside the bottle will also increases uniformly.
MARK THIS ANSWER AS THE BRAINLIEST PLEASE ❤️
An increase in pressure of a plastic bottle uniformly decreases by a factor of ten when the volume decreases.
What is pressure?Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.
There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .
It is a scalar quantity which is related to the vector area element with a normal force acting on it.It is distributed over solid boundaries and across arbitary sections of fluid normal to the boundaries at every point.Pressure and volume of gas are inversely proportional.

A pair of oppositely charged plates is separated by 0.09 m. A potential difference of
285 V exists between the plates. What is the electric field that exists between the plates?
Answer:
25.65 V/m
Explanation:
Applying,
V = Er................. Equation 1
Where V = Electric potential, E = electric field, r = distance of seperation.
make E the subject of the equation
E = V/r.............. Equation 2
From the question,
Given: V = 285 V, r = 0.09 m
Substitute these values into equation 2
E = (285×0.09)
E = 25.65 V/m
Hence the electric field between the plates is 25.65 V/m
