Electromagnetic radiation waves:
They can be either infared radiation or visible light
We cannot see I fared radiation but it is how some energy is transferred
Answer:
A) in between Earth and the sun.
Explanation:
During this phase, the dark portion of the moon is facing Earth, so the moon is not visible in the night sky.
Normally a storm surge.
Experience: I lived through Andrew and Wilma
Answer:
1) The volume of helium in the ballon when is fully inflated is 492.8070 m³
2) The magnitude of the force of gravity (with no people) is 869.3119 N
Explanation:
Given:
ρair = density of air = 1.28 kg/m³
ρhelium = density of helium = 0.18 kg/m³
R = radius of balloon = 4.9 m
mtotal = 121 kg
Vtotal = 0.073 m³
mp = average mass per person = 73 kg
Vp = 0.077 m³
g = gravity = 9.8 m/s²
Questions:
1) What is the volume of helium in the balloon when fully inflated, Vhelium = ?
2) What is the magnitude of the force of gravity on the entire system (but with no people), Fg = ?
1) The volume of helium in the ballon when is fully inflated
2) First, you need to calculate the mass of helium
The magnitude of the force of gravity (with no people)
