Answer:
The official measurement unit for energy is the Joule (J). Among the most common units measuring energy mention should be made of the kilowatt/hour (kWh), used especially for electric energy (in fact it is used to calculate electricity bills).
Explanation:
Answer: energy transformation
Before answering this question it is necessary to know the conversion factors for temperatures.
<em>273 k = 0 ° C
</em>
To transform a temperature from Kelvin to ° C we use the following Formula
T ° C = T Kelvin - 273
<u>For 373 K</u>
373K -273 = 100 ° C
<em>373 Kelvin equals 100° C.
</em>
To transform a temperature from ° C to ° F we use the following formula:
(T° C x 9/5) + 32 = T ° F
Then:
<u>For 0 ° C
</u>
(0° C x 9/5) +32 = 32 ° F
<em>0° C equals 32 ° F.
</em>
<u>For 100° C
</u>
(100 ° C x 9/5) +32 = 212 F
<em>100 ° C equals 212 ° F.
</em>
Therefore, the correct option is the first:
373 Kelvin = 100 ° C = 212 ° F
Answer:
the rock will continue at the same speed unless it is affected by another force such as gravity and so if you threw it it will continue to move unless affected by a force
Explanation:
this is because Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
Because of the earth's large mass and solid structure, the skier moves but the earth does not.
<h3>Why can't the earth be moved?</h3>
- Because the Earth is such a massive body, it cannot be moved by applying force to it. Because it cannot be moved with a small amount of force
- The amount of matter contained in an object is what gives it inertia, or the tendency of matter to remain at rest if at rest, or to continue moving in the same direction at the same speed if moving.
- The greater an object's mass, the greater its gravitational force.
- Mass is the quantity that is solely determined by an object's inertia. The greater an object's inertia, the greater its mass.
- A heavier object is more likely to resist changes in its state of motion.
- we can conclude that the skier moves but the earth does not due to the large mass of the earth and its solid structure.
