A condition that occurs when warm air traps cooler air at the surface of the earth is greenhouse gases.

Physics
1 answer:
gayaneshka [121]3 years ago

Answer:

FALSE

Explanation:

Temperature inversion usually refers to the situation where a warm air lies over a cooler air that is present from the surface of the earth up to a certain height.  

Normally, the temperature increases with increasing height. But, in the case of temperature inversion, the reverse of it takes place. This layer of inversion may occur at any place within the level of the troposphere.

This temperature inversion obstructs the atmospheric flow due to which the air mass present over a particular area become stable, resulting in a number of weather patterns.

On the other hand, greenhouse gases are those gases that can hold the incoming solar energy and radiate back into the atmosphere, thereby resulting in an increase in temperature of the atmosphere. Example, CO₂, CFC, H₂O and CH₄.

Hence, the above-given statement is false.

A parachutist with a camera, both descending at a speed of 10.8 m/s, releases that camera at an altitude of 50 m. In this proble
Vadim26 [7]

Answer:

The velocity of the camera is 33.11 m/s.

Explanation:

Given that,

Speed = 10.8 m/s

Altitude = 50 m

Suppose determine the velocity of the camera just before it hits the ground?

We need to calculate the velocity of the camera

Using equation of motion

v^2=u^2+2gs

Where, v = final velocity of camera

u = initial speed of camera

s = distance

Put the value into the formula

v^2=(-10.8)^2+2\times(-9.8)\times(-50)

v=\sqrt{1096.64}

v=33.11\ m/s

The direction will be downward so it is the negative velocity.

Hence, The velocity of the camera is 33.11 m/s.

4. show your understanding of electric and magnetic forces<br> below.
Vitek1552 [10]

Answer:

Explanation:

Electric forces exist among stationary electric charges; both electric and magnetic forces exist among moving electric charges. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

If a light Ray is aimed so that it bounces off a metal drain in a pool, the light Ray will reflect off the drain according to ?
Komok [63]

Answer:

B) the law of reflection

Explanation:

When a light ray reflects off a surface, it obeys the law of reflection.

A few definitions before giving the law of reflection:

- The angle of incidence is defined as the angle between the incident ray and the normal to the surface

- The angle of reflection is defined as the angle between the reflected ray and the normal to the surface

The law of reflection states that:

- The angle of incidence is equal to the angle of reflection

- The incident ray and the reflected ray lie both on the same plane.
