Answer:
The correct option is;
D. There is not enough information to answer this question
Explanation:
The universal gravitational constant = 6.67408 × 10⁻¹¹ 3³/(kg·s²)
For an in between distance of 1 m and equal masses of 60 kg, we have;
The gravitational attraction ≈ 2.403 × 10⁻⁷ N, which does not correspond with the answers, therefore, the best option is that there is not enough information to answer this question.

Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2
r
where C is the circumference and r its radius.
r = 
= 
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ = 
Tan 55 = 
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.

sustained by energy from sunlight. This energy is transmitted from sun
to Earth in the form of electromagnetic radiation emitted by hot gas at
the sun's surface. The sun is heated by nuclear fusion taking place
