It should be S since S stands for students. Giving the team with more members the upper hand. Hope this helps.
Answer:
Explanation:
Let Torque due to friction be
F
Net torque
= 46 - F
Angular impulse = change in angular momentum
=( 46 - F ) x 17 = I X 580
When external torque is removed , only friction creates torque reducing its speed to zero in 120 s so
Angular impulse = change in angular momentum
F x 120 = I X 580
( 46 - F ) x 17 = F x 120
137 F = 46 x 17
F = 5.7 Nm
b )
Putting this value in first equation
5.7 x 120 = I x 580
I = 1.18 kg m²
add the river's velocity to the boat's velocity
5+ 5 = 10 km/h

PH measures the concentration of hydrogen ions (
) in a solution. Knowing this, you can determine how acidic -or basic- your solution is.
