Answer:
The force exerted by the legs on the person's upper body 32.106 N.
Given:
Mass = 69 kg
Acceleration = 1.45 
To find:
Force exerted by legs on the person's upper body = ?
Formula used:
Force = mass × acceleration
Solution:
Mass of legs = 
mass of body
Mass of legs = 22.08 kg
According to Newton's second law of motion,
Force = mass × acceleration
Force = 22.08 × 1.45
Force = 32.106 N
The force exerted by the legs on the person's upper body 32.106 N.
Answer:
Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation.
Answer:
T = 51.25°C
Explanation:
Applying the law of conservation of energy, we get:
where,
m₁ = mass of cold water = 175 g
m₂ = mass of hot water = 125 g
T = Final temperature of the mixture = ?
Therefore,
<u>T = 51.25°C</u>
