If it starts at rest the initial velocity is 0.
For an acceleration, a, and time, t, the velocity is v=at. Since at t=4, v=7, then a=7/4=1.75m/s^2
Earth has its own atmosphere. That is one reason all the water that has been on Earth has been recycled through the water cycle. It never leaves Earth’s atmosphere.
<h2>
Time taken by dryer to come up to speed is 1.625 seconds.</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 rad/s
Final velocity, v = 5.2 rad/s
Time, t = ?
Acceleration, a = 3.2 rad/s²
Substituting
v = u + at
5.2 = 0 + 3.2 x t
t = 1.625 s
Time taken by dryer to come up to speed is 1.625 seconds.
When two tectonic plates move in opposite directions, it causes magma to rise, creating a new seafloor.
B) The transfer of energy from the hydrosphere to the atmosphere
This is because oceans are part of the hydrosphere. As the air warms it flows up into the atmosphere.
Hope this helps!
