Which statement about atmospheric pressure near earth's surface is true

Physics
1 answer:
Artemon [7]3 years ago
7 0

The correct answer is it decreases as someone moves away from earth's surface.

The atmospheric pressure decreases when you go near the surface of the earth. Atmospheric pressure can also be referred to as barometric pressure.

This is the pressure which is being found in the earth's atmosphere. It is approximated by pressure of hydrostatic which is known to be caused by weight of air where the measurement points are above.

When elevation increases, there is decrease in atmospheric pressure.

Force per unit are is measured by pressure.

The magnitude of the weight of a 3.0 kg object on the surface of the earth is 29 N. True False
madreJ [45]
True

In fact, the weight of an object on the surface of the Earth is given by:
F=mg
where m is the mass of the object and g=9.81 m/s^2 is the gravitational acceleration on Earth's surface. If we use the mass of the object, m=3.0 kg, we find
F=mg=(3.0 kg)(9.81 m/s^2)=29 N

A woman takes her dog rover for a walk on a leash. She pulls on the leash with a force of 30.0 N at an angle of 29° above the ho
IrinaK [193]

19.8 N force is tending to lift Rover vertically off the ground.

<h3>What is horizontal and vertical component?</h3>

The horizontal velocity component (v_{x}) describes the influence of the velocity in displacing the projectile horizontally. The vertical velocity component (v_{y}) describes the influence of the velocity in displacing the projectile vertically.

According to the question,

The women pulls the dog with a force of 30 N at an angle of  29° from the horizontal.

Horizontal component=  30cos(29°) = 22.2 N

Vertical component = 30sin(29°) = 19.8 N

Therefore,

The horizontal component would tend to make the dog move forward and the vertical component would tend lift it off the ground.

Hence,

19.8 N force is tending to lift Rover vertically off the ground.
