The concept of a black hole seem reasonable to me because of its valid and authentic evidences.
<h3>What are the causes, characteristics, and major features of black holes?</h3>
A black hole is a region in space where light is unable to escape due to strong gravitation force. The strong gravity is formed because matter has been pressed into a tiny space. This compression occurs at the end of a star's life. Some black holes are formed when a stars die.
So we can conclude that the concept of a black hole seem reasonable to me because of its valid and authentic evidences.

Answer:
angle = 18.40 degree
Explanation:
given data
force = 95 N
distance = 0.50 m
torque = 15 N · m
to find out
angle between the wrench handle and the direction of the applied force
solution
we will apply here torque equation that is express as
torque = distance × force × sin(θ) ...................1
put here value we will get angle that is
15 = 0.50 × 95 × sin(θ)
sin(θ) = 0.315789
θ = 18.40 degree
Answer:
v₁ = 5 m/s
Explanation:
We can use the law of conservation of momentum here:
where,
m₁ = m₂ = m = mass of each disk
u₁ = initial speed of yellow disk = 0 m/s
u₂ = initial speed of orange disk = 5 m/s
v₁ = final speed of yellow disk = ?
v₂ = final speed of orange disk = 0 m/s
Therefore,
<u>v₁ = 5 m/s</u>
