Wind driven currents create in the equatorial and warm zones of the earth’s oceans. The currents then transmit the warm water north, where the heat in the water is misplaced to the colder atmosphere. In the instance of the Gulf Stream, this transmission of heat to the air warms up England and Europe.
As the water cools, its' density upsurges because of chilling and increasing salinity. This cold water drops to the bottom of the ocean, where it is then stimulated by another current back south, similar to a train creating a big circuit.
The particles which are in the field of forces means in the field line of forces they experience electric force.
Explanation:
Every mass is attracted to every other mass with a force that is proportional
to the product of both masses and inversely proportional to the square of the
distance between their centers of mass. The forces act along the line between
their centers of mass.
Answer:
P = mv
Explanation:
P = Momentum
m = mass
v = velocity
Therefore, P = 10 x 13 = 130 kg • m/s
<span>Choice-C (the 3rd one on the list) is sorta kinda on the right track, and it's
the answer that the question is fishing for, but it has a glaring error.
An example of the Doppler shift:
If a star is moving toward us, then the frequency of the light we see
from the star appears higher than it was when it left the star.
The frequency of the light does NOT "increase as the star moves toward us".
It's constant and it doesn't change. It just appears higher than it should be.
The whole trick to this kind of observation is this: When we receive light from
a star and measure its frequency, HOW do we know what it SHOULD BE ? ! ?</span>
