Answer:
c) 3176 J
Explanation:
mass of 125 popcorn = 125 x .0001 = . 0125 kg
increase in temperature = 175 - 21 = 154°C
specific heat of popcorn = 1650
heat required to increase temperature
= mass of popcorn x increase in temperature x specific heat
= .0125 x 154 x 1650
= 3176.25 J
Answer:
F = 85696.5 N = 85.69 KN
Explanation:
In this scenario, we apply Newton's Second Law:

where,
F = Upthrust = ?
m = mass of space craft = 5000 kg
g = acceleration due to gravity on surface of Kepler-10b = (1.53)(9.81 m/s²)
g = 15.0093 m/s²
a = acceleration required = 2.13 m/s²
Therefore,

<u>F = 85696.5 N = 85.69 KN</u>

Photon energy is directly proportional to the frequency of electromagnetic radiation.
(That would also mean that it's inversely proportional to the wavelength.)
So the photon energy increases as you scan the chart of visible colors
moving from the red end of the rainbow to the blue end.
