The object that I think has potential energy within the images posted is the skateboard at the top of the ramp.
<h3>Why do i think this one has potential energy?</h3>
Potential energy is a type of mechanical energy in which there is a type of stored energy that can be transformed into another type of energy. This energy is given by the <u>location of the body</u> with respect to a force field.
I selected the image of the skateboard at the top of the ramp since going up there uses kinetic energy and when it is on top of the ramp, waiting to go down, this kinetic energy is stored in potential energy that is ready to be released. The higher the height at which it is launched, <u>the more its potential energy will be</u>.
Therefore, we can confirm that the object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

Answer:
A. SrSO4
Explanation:
it is insoluble in water therefore it is the precipitate formed in the reaction
Answer:
i would assume that it would be (a)
Explanation:
The Sun generates its energy by nuclear fusion
NUCLEAR FISSION is when the heavy atom is split
fusion energy is scientifically feasible. Plasma conditions that are very close to those required in a fusion reactor are now routinely reached in experiments
mass gets lost is nuclear fusion
so (a) is the most accurate
Answer:
38.0 g C2F3Cl3) / (187.3756 g C2F3Cl3/mol) x (3 mol Cl / 1 mol C2F3Cl3) x (35.4532 g Cl/mol) =
21.6 g Cl in C2F3Cl3
The temperature if the volume were changed to 225 ml at a pressure of 785 torrs is 129K.
Pressure is constant.
so
V1 / T1 = v2 / T2
so
T2 = V2 T1 / V1
T2 = 225 x 242 / 422
T2 = 129K
What is temperature?
Temperature is a measure of hotness or coldness expressed on several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which thermal energy spontaneously flows - ie, from a hotter body (one at a higher temperature) to a colder body (another at a lower temperature).
The Fahrenheit temperature scale (°F) is used in the United States and some other English-speaking countries. The Celsius temperature scale (°C) is standard in almost all countries that have adopted the metric system and is widely used in science. The Kelvin (K) scale, the absolute temperature scale is recognized as the international standard for scientific temperature measurement.
