A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.

<h3>What is Uniformly Accelerated Motion?</h3>

Uniformly Accelerated Motion is the motion of an object where the acceleration is constant.

A car starts from rest, that is, its initial speed is 0 m/s. It accelerates at 9 m/s². We can find the final speed after 240 m using the following kinematic equation.

v² = u² + 2 × a × s

v² = (0 m/s)² + 2 × (9 m/s²) × 240 m

v = 66 m/s

where,

  • v is the final speed.
  • u is the initial speed.
  • a is the acceleration.
  • s is the displacement.

A car starts from rest and accelerates at 9 m/s². After 240 m. the final speed is 66 m/s.

solmaris [256]

False The atmosphere's general circulation actually depicts the air flow around the world, not just an average.

<h3>What is global circulation in general?</h3>

The necessary transportation of heat from tropical to polar latitudes is performed by a system of winds that is known as the global circulation. Hadley cell, Ferrel cell, and Polar cell are the three cells in each hemisphere where air flows across the whole depth of the troposphere.

<h3>What type of nighttime air circulation pattern is typically linked with coastlines?</h3>

The wind turns around and blows out over the ocean at night because the land cools more quickly than the water. This is known as a land breeze. Additionally, the sun's rays have an impact on large-scale atmospheric circulation.
