Describe how does the temperature relate to density and the movement of atmospheric gases? A) As the air warms expanding its vol

ume, decreasing its density, and the air molecules rise. B) UV light causes air to warm its volume declines, density increases, and the air molecules sink. C) The volume of air distends as it cools, while its density increases and the air molecules descend. D) Radiation cools the air and its volume extends, density diminishes, and the air molecules accelerate.

The correct answer is A) As the air warms expanding its volume, decreasing its density, and the air molecules rise

The air molecules speed up and spread. If the container is closed then it may pop because the air expands. Hot air goes up and cold air goes down.

The x vector component of a displacement vector has a magnitude of 146 m and points along the negative x axis. The y vector comp
larisa86 [58]

Answer:  

a) the magnitude of r is  184.62

b) the direction is 37.74° south of the negative x-axis

   

Explanation:

Given the data in the question;

as illustrated in the image blow;

To find the the magnitude of r, we will use the Pythagoras theorem

r² = y² + x²

r = √( y² + x²)

we substitute

r = √((-113)² + (-146)²)

r = √(12769 + 21316 )

r = √(34085 )

r = 184.62

Therefore, the magnitude of r is  184.62

To find its direction, we need to find ∅

from SOH CAH TOA

tan = opposite / adjacent

tan∅ = -113 / -146

tan∅ = 0.77397

∅ = tan⁻¹( 0.77397 )

∅ = 37.74°

Therefore, the direction is 37.74° south of the negative x-axis

what is the force of friction between an 80kg box and the ground on Earth if the coefficient is 0.2?​
Reil [10]

Answer:

160N

Explanation: When 80kg mass is one group . It's reaction force acting on a ground.

Weight of the object = 80*10

= 800 N

Here we are given cofficient of static friction its 0.2. It should be smaller than 1

Friction force = Reaction * Friction Cofficient

Reaction = 800N ( Considering Vertical Equilibrium )

F = 800* 0.2

F = 160N
