Answer:
Kinetic energy is the energy obtained from movement while potential energy is the energy in something when it is at a height or has been manipulated in some way; it has work done to it.
Explanation:
Kinetic energy is, like I said, energy gained through movement or action. When an object stops moving, it converts into a different type of energy. Energy cannot be destroyed or created. An object with potential energy has a reference. A reference determines how high it is. The higher and heavier an object is, the more potential energy it has.

What is the speed in meters per second of a car that is travelling at 82km/h?
Answer:
22.777777777777 m/s
Explanation:
Since 1 kilometer is 1000 meters, then 82 km is 82000 meters. Since one hour is the same as 3600 seconds, then the answer is pretty simple: 82000/3600 or 820/36. That gets you 22.77777 or 22.78. Hope this helps
if a large bust and small cardboard going the same speed which vehicle has more kinetic energy
Answer:
bust
Explanation:
At the same speed, kinetic energy is proportional to mass. The more massive object (the large bust) will have more kinetic energy.
Answer:
Bust
Explanation:
the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

A cannonball is shot from the top of
a 47.8 m high hill at a speed of
53.7 m/s. At its highest point, it is
moving at 31.5 m/s.
How high is it then?
A cannonball is shot from the top of a 47.8 m high hill at a speed of 53.7 m/s. The height then is 61.81 m/s.
What are kinematic equations?The motion of an object with constant acceleration is described by a set of equations known as kinematic equations. Integrals, derivatives, and rates of change must all be understood in order to solve kinematics equations.
Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector, whereas speed is a scalar value.
The kinematic equation is:
v² = u² + 2gs (a = g)
Where u is the initial velocity, a is the acceleration, and v is the velocity after the time period t.
(53.7)² + 2 x 9.8 x 47.8 m
Therefore, the height is 61.81 m/s.

C. No
D. Inappropriate
Answer:
B
Explanation:
edge 2020
The emotional symptoms that may occur in those with a Schizophrenic disorder generally include all of the following except appropriate emotion. Hence, option (B) is correct.
What is schizophrenic disorder?Schizophrenia is a persistent, severe mental illness that has an impact on a person's relationships with others as well as their thinking, acting, and emotional expression. Despite not being as prevalent as other severe mental illnesses, schizophrenia can be the most persistent and incapacitating.
Schizophrenia patients frequently struggle to function well in relationships, the workplace, and academic settings. They can appear to have lost their sense of reality, feel afraid and withdraw. This chronic illness cannot be cured, but it can be managed with the right care.

What is temperature? Using the example of the pot of boiling water, describe how you think temperature is related to thermal energy.
Answer:
An example would be "The soup is boiling hot and has a temperature of 100 °C, whereas the water in the tub is just comfortably warm, with a temperature of about 38 °C. Although the water in the tub has a much lower temperature, it has greater thermal energy".
Explanation:
Thermal energy and temperature are closely related. Both reflect the kinetic energy of moving particles of matter. However, temperature is the average kinetic energy of particles of matter, whereas thermal energy is the total kinetic energy of particles of matter.

What is a magnet?Anything that creates a magnetic field is considered to be a magnet. The most noteworthy characteristic of a magnet—a force that drags on other magnetic elements like iron, steel, etc.—is caused by this invisible magnetic field, which also attracts or repulses other magnets.
A piece of equipment built from a substance that has been magnetized and produces a consistent magnetic field is called a permanent magnet. A typical illustration is a fridge magnet used to keep notes on the door of the refrigerator. The term "ferromagnetic" refers to substances that can be attracted and are also powerfully drawn to a magnet.
These comprise several naturally occurring minerals, some alloys including rare-earth metals, and the elements iron, nickel, and cobalt and their alloys.
It is the property of the magnet that opposite poles attract each other, while the same poles repel each other.

5 A swimming pool is 50m long. A
swimmer covers it in 50s. Calculate
the average speed of the swimmer.
the answer is 150 000 s2
The average speed of the swimmer is equal to 1 m/s.
What is the average speed?The average speed can be defined as the total distance traveled by the object in a specific time interval. The average speed can be defined as a scalar quantity as it possesses only the magnitude and does not have any direction.
The average speed can be determined from the ratio of the total distance the object covers to the time taken to travel that distance.
The equation for average speed can be written as follows:
Average speed = Total distance/Total time taken
Given, the distance covered by the swimmer = 50 m
The total time taken by the swimmer = 50 sec
The average speed of the train = 50/50 = 1 m/s
Therefore, the average speed of the swimmer is equal to 1 m/s.

When does the ball hit the ground?
Answer:
t = 2.38 [s]
Explanation:
To solve this problem we must use the following equation of kinematics. We must clarify that both the acceleration and the initial velocity were taken as positive, since the velocity of the movement coincides with the direction of the acceleration.
[tex]x =x_{o} +v_{o} *t+(\frac{1}{2} )*a*t^{2}[/tex]
where:
x - Xo = distance = 47 [m]
Vo = initial velocity = 8 [m/s]
a = gravity acceleration = 9.81 [m/s²]
t = time [s]
Now replacing these values in the equation:
47 = 8*t + 0.5*9.81*t²
47 = 8t + 4.905t²
47 = 4.905*t(1.63 + t)
9.58 = t*(1.63 + t) solving this equation (cuadratic)
we found that t = 2.38 [s]
A farmer is pushing a 75 kg plow across a field with 700 N at an angle of 35 degrees above the ground. If the kinetic frictional force between the plow and the field is 250 N. What is the Normal Force from the ground onto the plow? And what is the acceleration of the plow?
Given :
A farmer is pushing a 75 kg plow across a field with 700 N at an angle of 35 degrees above the ground.
The kinetic frictional force between the plow and the field is 250 N.
To Find :
The Normal Force from the ground onto the plow.
The acceleration of the plow.
Solution :
Normal force = mg + F sin Ф
= 75×10 + 700 × sin 35°
= 1151.50 N
Now,
ma = 700 cos Ф - 250
75×a = 323.4
a = 4.31 m/s²
Hence, this is the required solution.

A helicopter is dropping a package of rescue supplies to a group of stranded hikers. If it drops the supplies while it is hovering 172m above the hikers, how long does it take to hit the ground?
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the average velocity at which the supplies are travelling in air. The formula to be used here if the completed question is obtained is
Average velocity (in m/s) = distance (m) ÷ time (s)
Since we are looking for the time, then time should be made the subject of the formula
time (in secs) = distance ÷ average velocity

Explain why the focal point of a diverging lens is called a virtual focal point.
Why does a bowling ball and a feather hit the ground at the same time when they are dropped in a vacuum?
Answer:
See the explanation below.
Explanation:
This is because the vacuum chamber removes all the air contained and for this reason, there is no force that opposes the movement of the feather when falling. We must remember that the free fall equation of kinematics is not a function of the mass of an object.
[tex]v_{f} =v_{o} +g*t[/tex]
where:
Vf = final velocity [m/s]
Vo = initial velocity [m/s]
g = gravity acceleration [m/s²]
t = time [s]
As we can see the mass of the object is not included in the equation.
