What is the mass of the diver in (Figure 1) if she exerts a torque of 2200 N⋅m on the board, relative to the left (A) support post? A-->B = 1.0m
B--> end of board = 3.0m

56.1 kg

Explanation:

Given

-- torque

Required

The mass of the diver

From the question, we understand that the diver is at the extreme of the board.

So, we make use of the following torque equation

Where:

So, we have:

Divide both sides by 4.0

--- This is the force exerted by the diver (in other words, the weight).

To calculate the mass, we use:

Make m the subject

This gives:

are there answer choices to this question? this seems like a question where you have options to choose from.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
