Answer:
83%
Explanation:
On the surface, the weight is:
W = GMm / R²
where G is the gravitational constant, M is the mass of the Earth, m is the mass of the shuttle, and R is the radius of the Earth.
In orbit, the weight is:
w = GMm / (R+h)²
where h is the height of the shuttle above the surface of the Earth.
The ratio is:
w/W = R² / (R+h)²
w/W = (R / (R+h))²
Given that R = 6.4×10⁶ m and h = 6.3×10⁵ m:
w/W = (6.4×10⁶ / 7.03×10⁶)²
w/W = 0.83
The shuttle in orbit retains 83% of its weight on Earth.
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
Just plug in the values of v and t...that will give the magnitude of average acceleration
Answer:
can a fire have a shadow?
Yes it can actually.
edit:Fires can have shadows because they contain hot air and soot, and not because they contain light.
