Answer:
The velocity is 31.25 m/s and direction is toward west.
Explanation:
Given that,
Distance
Magnetic field
Mass of proton
Radius of earth
Radius of orbit
We need to calculate the speed
Using formula of magnetic field
Put the value into the formula
Hence, The velocity is 31.25 m/s and direction is toward west.
Answer:
1.01 × 10⁵ Pa
Explanation:
At the surface, atmospheric pressure is 1.013 × 10⁵ Pa.
We need to find the total pressure on the air in the lungs of a person to a depth of 1 meter.
Pressure at a depth is given by :
Where
is the density of air,
So,
Total pressure, P = Atmospheric pressure + 12 Pa
= 1.013 × 10⁵ Pa + 12 Pa
= 1.01 × 10⁵ Pa
Hence, the total pressure is 1.01 × 10⁵ Pa.
