Answer:

Explanation:
Area of the solar sail = A = 30 m2
Solar constant = I = 1388 W/m2
Planck's constant = h = 6.626 × 10⁻³⁴ m²kg/s
Speed of light = c = 3×10⁸ m/s
Wavelength of light =
= 570 nm
Pressure from radiation

Energy of a photon

Number of photons

Number of photons is 
We simply use the formula,

Given, velocity = 4 m per s and distance = 120 m.
Substituting these values, we get
.
Thus, required time for the elevator in order to travel 120 m upwards is 30 s.
Answer:
heat came from the supernova that led to the formation of solar system
