Answer: D
Explanation: The chemical bonds in the food store energy that is released when we eat it.
Because the top layer of a pool will be warmer than the bottom layer, that why filtration is important to cycle the water evenly.
The answer is b) force exponerse by charge in electric field
The displacement is
(position at the end of the time interval)
minus
(position at the beginning of the time interval).
Displacement = (3.38m - 11.3m) = -7.92 meters.
The time labels aren't needed to calculate displacement.
They're only there to confuse us and to see whether we
really know what we're doing.
Answer:
See below
Explanation:
East components are 10 and 12 cos 30 = 20.392 m/s
North component = 12 sin 30 = 6 m/s
Resultant velocity = sqrt ( 20.392^2 + 6^2) = <u>21.26 m/s </u>
direction arc tan (6/20.392) = <u>16.4 degrees N of east </u>
