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
The upward force of the chain on the diamond would be the tension in the chain, and this tension would have to support the weight of the 45g that hangs from the chain.
mass = 45 g = 45/1000 kg = 0.045kg
Weight = mg = 0.045 * 10 ≈ 0.45N, g ≈ 10 m/s²
<span>So the upward force is ≈ </span><span>0.45N. </span>
The answer to this is
<span>A mass on a spring will oscillate vertically when it is lifted and released. The gravitational potential energy increases from a minimum at the lowest point to a maximum at the highest point. ... The total mechanical energy at those points is the sum of the elastic and gravitational potential energies.</span>
Hope This Helps!

Answer:
Each climber had to eat 72 slices of bread to compensate for the increase of the gravitational potential energy of the system climbers-Earth
Explanation:
Hi
One piece of bread releases about 
of energy in the body, but efficiency in converting the body's chemical energy into mechanical work is 9.5 %, so 
.
On the other hand, we need to calculate the total work to reach the top of Mt. Everest
, so 
Finally, we have that
