Answer:
First question: 2. Hold constant throughout the entire experiment
Second question: 2. One you change or manipulate. Everything depends on what you do to this variable.
Explanation:
Explanation:
Given
mass of coolie = 40 kg
Mass of salt = 20 kg
Total mass (m) = 40 + 20 = 60 kg
Displacement (h) = 20*20 = 400 CM = 4 m
Work done (w) = ?
Power (P) = ?
We know we have the formula
work done =force × displacement
or work done = m * g * h
work done = 60×10×4
work done = 2400 joules
Similarly
power = work/time
power = MGH/time
power=60×10×4/120
power=2400/120
power= 20watt

The strength training is an exercise, which increases the strength and the stamina of the muscles. It helps in reducing the anaerobic endurance, and hence, prevent the muscles from fatigue.
The strength training combined with aerobic exercises help in the increase in the muscle mass. It also decreases the adipose tissues present around the muscles, hence, help in acquiring extra fat free body.
So, the correct answer is :
A benefit of strength training, accentuated even more when combined with aerobic exercise, is a decrease in the adipose tissues around the muscles.
they fly best in the troposphere
