Answer:
Acceleration =0
Explanation:
There are two forces on the box in horizontal direction.
First one is horizontal component of 30N at 45°.
Another one is given in opposite to direction of motion mean opposite to this force.
Which is = 2.22 N
Now we know F (net) =mass*acceleration(center of mass)
21.2-21.2 =10*acceleration
acceleration =0
the object con tinues to fall but with NNO acceleration! notice that there is not net force if the upward and dowward forces are equal.
Answer:
E =17,280 J
Explanation:
Since the voltage drops linearly from 6V to 4V, the average is 5V. The energy delivered is .
V is the average of initial and fianl voltage
A is the current passing
t is the time in which current is passed
E=V*A*t = 5*0.015*(64*3600) = 17,280 J

c.The warm surface water results in moist air and more rainfall.
Explanation:
- During upwelling, cold water in the ocean is stirred up and brought to the surface.
- The warmer surface water is then taken into deeper parts of the ocean.
- Upwelling allows for nutrient mixing in the ocean and allows for useful gases to circulate well.
- The warm surface water causes the air to be moisty.
- When the air is carried landward towards the coast, it leads to rainfall when the saturated air releases the water.
- The air then becomes cold and dry and it rises up.
- Therefore, warm surface water results in moist air and more rainfall.
