Answer:
The force of gravitational attraction is 8.454 x 10⁻⁸ N.
Explanation:
Given;
mass of the boy, m₁ = 78 kg
mass of the girl, m₂ = 65 kg
distance between the boy and the girl, r = 2 meters
The force of gravitational attraction is given as;
where;
G is gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²
r is the distance between two masses, m₁ and m₂
Therefore, the force of gravitational attraction is 8.454 x 10⁻⁸ N.
Apparent depth is dangerous for swimmers because
<span> When you look vertically downwards into a </span>swimming<span> pool full of water the bottom seems closer than it. </span>If the pool is really deep and it doesn't look deep to you that's not good cuz if you don't know how to swim in deep water you might drown.
Hope this helps ;)
