Differentiate elastic potential energy and chemical potential energy
Answer: Elastic energy is the energy store in a.. compacted spring; an extended elastic band; and a drawn bow.
Chemical potential energy is position of electrons in specific substance bonds that can be broken (energizes).
:
This stored energy is released and performs work when the elastic material reverts back to its original position. ... In comparison, chemical potential energy, is the energy released during the formation of chemical compounds.

MY PAPER IS DUE IN AN HOUR!!!
Your challenge- Write a paper on how to build, construct, and engineer a faster roller coaster. You essay must contain 5 paragraphs minimum. Each paragraph must be 3 sentences minimum.
Potential energy, Kinetic energy, Thermal energy and friction, speed, velocity, and acceleration, and the law of conservation of energy must be the main ideas of your paragraphs
Answer:
Your kinetic energy is always proportional to the square of your speed,
no matter whether you're on a bicycle, a roller coaster, or a baby carriage.
The faster you're moving, the more kinetic energy you have.
Your potential energy doesn't depend on speed at all, only on height.
On a roller coaster, the minimum speeds are usually at the top of a hill
or a loop, so the potential energy would generally correspond to the
slowest speeds. But again, that's not because of the speed. It's because
of the height.

a large bottle contains a number of medicinal tablets each having a mass of 250mg the mass of all the tablets is 0.5kg calculate the number of tablets in the bottle
Considering the change of units and rule of three, the number of tablets in the bottle is 2,000.
First of all, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 0.5 kg. You can see that the measurements are in different units of measurement, so you must make a change of units so that they are in the same units.
So, knowing that 1 kg is equal to 1,000,000 mg, you can apply the following rule of three: if 1 kg is equal to 1,000,000 mg, 0.5 kg is equal to how many mg?
1 kg ⇒ 1,000,000 mg
0.5 kg ⇒ x mg
So: [tex]x=\frac{0.5 kgx1,000,000 mg}{1 kg}[/tex]
x= 500,000 mg
Then, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 500,000 mg. Now that the values are in the same units, to calculate the number of medicinal tablets you must apply the following rule of three: if 1 tablet has a mass of 250 mg, how many tablets have a mass of 500,000 mg?
[tex]number of medicinal tablets=\frac{500,000 mgx1 tablet}{250 mg}[/tex]
number of medicinal tablets= 2,000
Finally, the number of tablets in the bottle is 2,000.

Answer: Is three times the height of Mt. Everest
Explanation:
Using the process of elimination we can rule out “D” Because its a volcano, C because it says we have visited mars 44 times not the volcano, B because in the passage is literally says “3 times the size of Mt. Everest”.

explain why you cant see our reflection better in a piece of metal
Answer:
metal and glass are very smooth and reflect light back more directly this is called specular reflection if you look into a lake on a wide windless day you will be able to see your reflection because of the smooth surface of the water is producing the specular reflection rather than diffuse reflection

what is the initial velocity of an object thrown straight up that takes 5 seconds to reach its highest point?
Answer:
50 [m/s].
Explanation:
1) formula is: V-V₀=g*t, where V₀ - final velocity (it is 0), V - required initial velocity, g≈10 [m/s²] and t - elapsed time.
2) according to the formula above:
V=g*t; ⇒ V=5*10=50 [m/s].

A ball is thrown straight up from the ground with an unknown velocity. It returns to the ground after 4.0 s. With what velocity did it leave the ground?
Answer:
It must return at the same velocity with which it was thrown or else there would be a preferred direction of motion leading to perpetual motion.
a = (v2 - v1) / t = (v2 - 0) / 2 = v2 / 2 for a falling object
v2 = 2 a = 2 sec * 9.8 m/sec^2 = 19.6 m/s
You can check with
H = V0 t - 1/2 g t^2 (V0 and g are in different directions)
H = 0
V0 = 1/2 g * 4 = 19.6 m/s

. Sunita is taking a train to Madurai. Her train has stopped at Trichinapally. She is facing the direction the train will be moving in . She can see a train next to her. The train is also going to Madurai and it leaves first. As the other train leaves, it seems to Sunita as if
The relative motion of the train next to her is the motion of the other train in her rest frame.
As the other train leaves, it seems to Sunita as if her train is moving backwards
Reason:
The motion of the train Sunita is taking is given by the rate of movement of
objects outside the train from the front side of the train towards the back
side of the train, that way she can tell that the train is moving.
The motion of the other train from the rear side of the train from the rear
side of the train to the front side is a reverse motion to what Sunita
observes when the train is moving forward. Therefore, as the other train
leaves, it seems to Sunita as if her train is moving backwards.
