Question

What is the gravitational acceleration on the board of the Deepsea Challenger when it is in the Mariana Trench, 11 km below the surface of the Pacific Ocean?

a. It is slightly less than 9.81 m/s2.
b. It is very large due to the high pressure.
c. It is zero.
d. It is significantly less than 9.81 m/s2.

Answer 1

The gravitational acceleration on the board of the Deepsea Challenger in the Mariana Trench is slightly less than 9.81 m/s^2.

Step-by-step explanation:

The gravitational acceleration on the board of the Deepsea Challenger in the Mariana Trench is slightly less than 9.81 m/s2. Although the pressure is high due to the depth, the gravitational acceleration is not significantly affected. The gravitational acceleration depends on the mass of the Earth, which remains constant regardless of the depth.
