<u>Answer:</u>
The height of ramp = 124.694 m
<u>Explanation:</u>
Using second equation of motion,
From the question,
u = 31 m/s; s = 156.3 m, a=0
substituting values
t = 
= 5.042 s
Similary, for the case of landing
t = 5.042 s; initial velocity, u =0
acceleration = acceleration due to gravity, g = 9.81 
Substituting in 
h = 124.694 m
So height of ramp = 124.694 m
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 °
Because it's placed in the lasagna, the thermal energy is transferred by conduction. Remember, convection is transfer of heat through fluids (liquids and gases), and radiation is just transfer of heat through air.
A false positive<span> is a conclusion that some effect occurred when in fact it did not. hope it helped but i am not 100%
