Answer:
420J
Explanation:
Given parameters:
Force = 2 x 10¹N
Speed = 3m/s
Time = 7s
Unknown:
Work done = ?
Solution:
Work done is the force applied on a body to move it through a particular distance.
Work done = force x distance
Now, let us find the distance;
distance = speed x time
distance = 3 x 7 = 21m
So;
Work done = 2 x 10¹ x 21 = 420J
What is the magnetosphere, and how does it help the earth?
The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind - the constant flow of charged particles streaming off the sun. ... It is generated by the convective motion of charged, molten iron, far below the surface in Earth's outer core.
Explanation:
Answer:
are always the same
Explanation:
angle of incident is equal to the angle of reflection i = r
the normal is perpendicular to the reflecting surface
Answer:
It be 0,1% - 49.9%
This is because the new moon is 0.0% and the first quarter is 50%.
