Only two horizontal forces act on a 3.0 kg body that can move over a frictionless floor. one force is 9.0 n, acting due east, an
Zolol [24]
The first thing you should do for this case is to find the horizontal and vertical components of the forces acting on the body.
 We have then:
 Horizontal = 9-9.2cos (58) = 4.124742769 N.
 Vertical = 9.2sin (58) = 7.802042485 N
 Then, the resulting net force is:
 F = √ ((4.124742769) ^ 2 + (7.802042485) ^ 2) = 8.825268826 N
 Then by definition:
 F = m * a
 Clearing the acceleration:
 a = F / m
 a = (8.825268826) / (3.0) = 2.941756275 m / s ^ 2
 answer:
 The magnitude of the body's acceleration is
 2.941756275 m / s ^ 2

The upward and downward movement of air in the atmosphere creates pressure systems. Arrange the steps in the correct order to de
OleMash [197]

Answer:

  1. Cool, dense air begins to sink downward.
  2. A high-pressure system forms.
  3. Pressure differences cause wind to blow outward.
  4. The skies clear, making way for pleasant weather.

Explanation:

The air near the land warms up and rises. Cool dense air sinks being heavier. This creates a pressure difference. A high pressure system forms. This difference leads to blowing of wind from High pressure to low pressure area. Eventually sky gets clear and we experience pleasant weather. Hence, the correct order to describe this is:

  1. Cool, dense air begins to sink downward.
  2. A high-pressure system forms.
  3. Pressure differences cause wind to blow outward.
  4. The skies clear, making way for pleasant weather.
