Answer:
108.217 °
Explanation:
Day of year = 356 = d (Considering year of 365 days)
Latitude of Tropic of Cancer = 23.5 °N
Declination angle
δ = 23.45×sin[(360/365)(d+284)]
⇒δ = 23.45×sin[(360/365)(356+284)]
⇒δ = 5.2832 °
Altitude angle at solar noon
90+Latitude-Declination angle
= 90+23.5-5.2832
= 108.217 °
∴ Altitude angle of the Sun as seen from the tropic of cancer on December 22 is 108.217 °

Explanation:
Momentum is defined as mass*velocity, so a doubling of velocity means a doubling of momentum
Answer:
To obtain the power, we first need to find the work made by the force.
1) To calculate the work, we need the next equation:
So the force is given by the problem so our mission is to find 'dx' in terms of 't'
2) we know that:
So we have:
Then:
3) Finally, we replace everything:
After some calculation, we have as a result that the work is:
161.9638 J.
4) To calculate the power we need the next equation:
So
P = 161.9638/4.7 = 34.46 W
