Actually Welcome to the Concept of the Potential Energy.
Here lets calculate it one by one ;-
1.) P = mgh ==> 100*9.81*202===> 198162 Joules
2.) P = mgh ==> 90*9.81*202 ==> 178345.8 Joules
3.) P = mgh ===> 45*9.81*202 ===> 89172.9 Joules
4.) P = mgh ===> 58*9.81*202 ===> 114933.96 Joules
5.) P = mgh ===> 0.001*9.81*202 ===> 1.981 Joules
6.) P = mgh ===> 1.00*9.81*202 ===> 1981.62 Joules
7.) P = mgh ===> 1.998*9.81*202 ==> 3959.27 Joules
8.) P = mgh ===> 1.5*9.81*202 ===> 2971.43 Joules
9.) P = mgh ===> 0.1*9.81*202 ===> 198.162 Joules.
Above we calculated the potential energy for every mass given above.

Answer:
magnetic resonance imaging (MRI)
Each bat can produce different frequencies of ultrasound. Explain why this is useful if there are many bats hunting together.
Answer: Although low frequency sound travels further than high-frequency sound, calls at higher frequencies give the bats more detailed information--such as size, range, position, speed and direction of a prey's flight. Thus, these sounds are used more often.

What happens to the force between charged and uncharged objects as the distance between them decreases?
Answer:Thus, if each of the charges were reduced by one-half, the repulsion would be reduced to one-quarter of its former value. Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.
Hope this helps have a awesome night/day❤️✨
Explanation:
Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.
(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)
So a better question would then be, what is gravity’s relationship with an electric field?
You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)
Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

Name two devices we use generators in. Describe how they work.
Answer:
There are two fundamental types of generators known as AC (alternating current) and DC (direct current) generators. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.
Explanation:
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. ... Instead, it uses the mechanical energy supplied to it to force the movement of electric charges present in the wire of its windings through an external electric circuit.

is boiling water in a kettle on a stove kinetic or potential energy?
Answer:
Boiling a kettle is an example of both thermal and kinetic energy. Thermal energy comes from a substance whose molecules and atoms are vibrating faster due to a rise in temperature. Heat energy is another name for thermal energy. Kinetic energy is the energy of a moving object.
it's kinetic!

Speed = Distance Time Velocity = 1. Find the velocity of a truck that travels 75miles north in 2.5 hours? List: Equation: Substitution: Answer with units:
Answer:
187.5 m/s (i think)
Explanation:
If you use the formula V= T times displacement you can find this out by doing the following-
Displacement equals 75 m
T equals 2.5 hrs
75x2.5= 187.5
and since velocity is measured in m/s, it becomes
187.5 m/s
Hank's mother got tired of everyone's cell phones ringing during dinner, so she wrapped all

The average kinetic energy of the particles of two pieces of iron at the same temperature and mass would be __________.
Question 1 options:
Different
The same
Not equivilent
With in 500 degrees of eachother
Answer:
The same.
Explanation:
Temperature is a measure of the average kinetic energy of a substance; if two pieces of iron have the same temperature, then their particles will have the same amount of average kinetic energy.
Answer 1 - The average kinetic energy of the particles of two pieces of iron at the same temperature and mass would be the same
Answer 2 - The particles of an object move FASTER when the temperature increases
Answer 3 - When a tight fitting lid is run under hot water, the lid
E/X/P/A/N/D/S as the temperature increases.
Answer 4 - I dont know sorry!
Answer 5 - What happens when something reaches absolute zero?
The p a r t i c l e s completely stop moving

. ........... is a mirror with a flat reflecting surface and is made of ordinary glass.
Answer:
Plane mirror.
Explanation:
A plain mirror is a mirror with a flat reflecting surface and is made of ordinary glass.
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface such as a plane mirror.
Generally, the angle of reflection equals the angle of incidence when a light ray strikes or hits a plane mirror.
The properties or characteristics of the images formed by a plane mirror include;
I. They are virtual and erect (upright).
II. It is the same size as the object formed.
III. It has the same distance from the plane mirror as the distance of the object from the mirror.

A sharpening wheel is traveling at 5 rad/s, it slows down to rest in 30 seconds while sharpening an axe. What is its angular acceleration?
Answer:
Angular acceleration [tex]= 0.167[/tex] rad/s^2
Explanation:
Given
Initial Angular velocity (w1) [tex]= 5[/tex] rad/s
Final Angular velocity (w2) [tex]= 0[/tex] rad/s
Time taken to change velocity from w1 to w2 [tex]= 30[/tex] seconds
Angular acceleration is equal to the change in angular velocity to the time taken for making thing change
Hence, Angular acceleration
[tex]\frac{w_2 -w_1}{t} \\\frac{5-0}{30}\\0.167[/tex]rad/s^2
