Explanation:
Let the speed of the drone relative to earth be u = ?
Let the speed of the drone relative to the starship be u' = 0.5c
Let the speed of the starship relative to earth be v = 0.8c
In the theory of relativity,
The 3 speeds are related thus
u = (u' + v)/[1 + (u'v/c²)]
u = (0.5c + 0.8c)[1 + ((0.8c × 0.5c)/c²)]
u = 1.3c/[1 + (0.4c²/c²)]
u = 1.3c/1.4 = 0.9286 c = 0.93 c = 93% c

Answer:
See the explanation below
Explanation:
To better understand this problem, a cylinder sketch is attached before and after the cut, we see that after the cut, the shape of this resembles that of a right triangle.
We can find, the centroid in the xy plane, knowing that the centroid for a triangle is located a third of its base.
In the z axis there is no displacement of the centroid.
Answer: yes.
Explanation: The light that will be incidented on that metal is visible light.
It depends on 3 factors:
1. The temperature
2. The specific heat capacity of the metal
3. The thermal conductivity of the metal.
The metal getting warmer also depend on the reflection and the absorption of light energy in which it will surely absorb some energy and not reflect all.
When visible light is absorbed by an object, the object converts the short wavelength light into long wavelength heat. This causes the object to get warmer.
Answer:
Explanation:
delta V = v * alpha * delta T
= V * 0.00053 * (92.2 - 55.0)
= 0.019716 V
percentage that the owner
= [delta V / V] * 100
= [0.019716 V / V] * 100
= 1.9716 %
