When warm currents move over cool land surface, they dissipate heat due to
the temperature gradient . They hence warm up the land they blow over. If a
cold current blows over warm land, the land loses heat to the current. This is
how currents distribute heat across the earth.
When the current blow from water to land, the current will be warm or cold
depending on the water temperatures. Therefore, they will warm up or cool the adjacent
land mass.
Answer:
F - M a force exerted by scales on student
M a = M (9.8 + 4.9) m/s^2 upwards chosen as positive
a = 1.5 g net acceleration of student due to force of scales
W =M g weight of student (actual weight)
Wapp = M 1.5 * g apparent weight (on scales) of student
Answer:
Explanation:
Momentum is the mass of a moving body times its velocity. It can be transferred from one object to another
Use Force=Mass x Acceleration (newtons second law states force is directly proportional to the acceleration) so you can say that the force is negative and solve for Acceleration.
