Answer:
b) True. the force of air drag on him is equal to his weight.
Explanation:
Let us propose the solution of the problem in order to analyze the given statements.
The problem must be solved with Newton's second law.
When he jumps off the plane
fr - w = ma
Where the friction force has some form of type.
fr = G v + H v²
Let's replace
(G v + H v²) - mg = m dv / dt
We can see that the friction force increases as the speed increases
At the equilibrium point
fr - w = 0
fr = mg
(G v + H v2) = mg
For low speeds the quadratic depended is not important, so we can reduce the equation to
G v = mg
v = mg / G
This is the terminal speed.
Now let's analyze the claims
a) False is g between the friction force constant
b) True.
c) False. It is equal to the weight
d) False. In the terminal speed the acceleration is zero
e) False. The friction force is equal to the weight
The energy that substance contain is. B.heat
Your options are:
A) It is located at a distance of 2.6 million light years from Earth.
B) It has to travel a distance of 2.6 million kilometers to reach Earth.
C) It can be photographed by a space telescope in 2.6 million years.
<span>D) It has to move at the rate of 2.6 million kilometers per hour to reach Earth
You need to remember the definition of lightyear: one lightyear is the distance that light can travel in one year through space. It is a measure of astronomical distances and it is equal to 9.5×10¹²km.
Therefore, if light takes 2.6 million years to reach Earth, it means that the Andromeda Galaxy is at a distance of 2.6 million lightyears from Earth.
Hence, the correct answer is A) </span><span>It is located at a distance of 2.6 million light years from Earth.</span>
