W = Fd = 4(2100) = 8400 J
So the answer is A) 8400 J
I was just rewriting my notes on the work lesson I did in class today, so I saw this question at the perfect time!! :)
Hope it helps!! :)
Answer:
D
Explanation:
Maybe your question is meant to be: which is not a wedge, because wedge is a combination of two inclined planes, use to separate bodies which are held together by large forces. Option A,B & C are all wedge except D.
Answer:
Diodes helps in maintaining proper voltage levels
Explanation:
Electronic components such as diodes allow current to flow in forward biasing.
Under reverse biasing diode does not allow current to flow but a negligible amount of current does flow.
Forward biasing allow current to flow after crossing potential barrier
.
When crossing this potential barrier we can observe an increase in current but the voltage does not go higher than
. Even with the high input voltage.
Hence, diode maintains proper voltage in circuits.

Stream-like movements of ocean water located far below the surface are called deep currents. Deep currents are not controlled by wind. B. Deep currents form in parts of the ocean where water density increases. The density of the ocean is affected by temperature and salinity.
