Answer:
Light with a wavelength of 100 nm is completely absorbed by the atmosphere. True
Light with a wavelength of 400 nm has the color of red. False
Light with a wavelength of 280 nm is in the ultraviolet region. False
Explanation:
Light of wavelength 0-100nm can be absorbed by the earths atmosphere
Ultraviolet light ranges between 320-400nm hence the statement above is false.
The wavelength of red colour is around 620-700nm hence the statement above is false.
Answer:The greater the mass, there greater then gravitational pull on their objects.
There greater the distance,the lower the gravitational pull between the object
Explanation:
Gravitational pull(force) is directly proportional to the products Of The masses. therefore if the mass increase,the gravitational pull(force) also increases.
Gravitational pull(force) is inversely proportional to distance.if the distance between the objects increases,the gravitational pull(force) decreases .
yes
evaporation starts on the surface
Answer:
increases
Explanation:
because as when the electimagnatics coul coul starts to increase the magnetic field also increases
Answer:
<em>The radius of the balloon is R= 0.974 m</em>
Explanation:
Atmospheric density on the surface of mars ρ = 0.0154 kg/m³
Mass density of balloon σ 5 gm/m² = 0.005 kg/m²
Total mass of balloon M = density of balloon* surface area
The balloon is considered as sphere
Surface area of sphere is given by 4π R²
Mass of balloon is M =σ *4πR²
M= (0.005 kg/m²)*(4π R²)
Volume of balloon is given by 
πR³
Density of atmosphere of mass is given by
ρ = Mass of balloon/volume of balloon
=(0.005 kg/m²)*(4π R²)/ πR³
Re arranging R
R = 
R = 0.974 m
<em>The radius of the balloon is R= 0.974 m</em>
