The answer would be B.

Standard deviation basically measures how spread out the values are. Without solving, you can easily tell which one among your choices have a smaller deviation. The closer the values are to each other the smaller the standard deviation. The values of choice B are the closest together, so you can assume that they have the smallest standard deviation. </span>
In my text book for social studies it says a canal
Its acceleration is constant.
The net torque on the seesaw is 294 Nm.
<h3>What is torque?</h3>
Torque is the force that tends to rotate the body to which it was applied.
To calculate the net torque, we use the formula below
Formula:
- τ = mgd-m'gd'........... Equation 1
Where:
- m = Jenny's mass
- m' = Tom's mass
- d = Jenny's distance from the pivot
- d' = Tom's distance from the pivot
- g = acceleration due to gravity
From the question,
Given:
- m = 40 kg
- m' = 30 kg
- d = 1.5 m
- d' = 1 m
- g = 9.8 m/s²
Substitute these values into equation 1
- τ = (40×1.5×9.8)-(30×1×9.8)
- τ = 588-294
- τ = 294 Nm
Hence, The net torque on the seesaw is 294 Nm.
