Answer:
The correct answer is A. Friction
Explanation:
Surface winds typically blow at an angle to isobars on a weather map, while winds aloft move air in a direction nearly parallel to the isobars. FRICTION is the factor that best explains why surface winds move differently than winds aloft.
Friction is a force that holds back the movement of a sliding object. It is also the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
It is also the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Answer: ![2.0416(10)^{42}kg](https://tex.z-dn.net/?f=2.0416%2810%29%5E%7B42%7Dkg%20)
Explanation:
Approaching the orbit of the Large Magellanic Cloud around the Milky Way to a circular orbit, we can use the equation of velocity in the case of uniform circular motion:
(1)
Where:
is the velocity of the Large Magellanic Cloud's orbit, which is assumed as constant.
is the Gravitational Constant and its value is
is the mass of the Milky Way
is the radius of the orbit, which is the distance from the center of the Milky Way to the Large Magellanic Cloud.
Now, if we want to know the estimated mass of the Milky Way, we have to find
from (1):
(2)
Substituting the known values:
(3)
<u>Finally:</u>
>>>This is the estimated mass of the Milky Way
