How much power is expended if you lift a 60 n crate 10 meters in 1 second?
The correct answer is <u>600w</u>

The reason the United States acquired the Midway Islands was<u> to </u><u>build naval protection </u><u>against </u><u>rivals </u><u>as the</u><u> United States</u><u> increased </u><u>trade </u><u>with </u><u>Asia </u><u>and </u><u>Latin America.</u>
<u />
The Midway Islands:
- Were the first territories in the Pacific that the U.S. acquired.
- Came under the administration of the U.S. Navy.
With the U.S. Navy controlling the islands, we can therefore say that the U.S. acquired the islands as a means of navy protection for American trade in Asia and related areas.
In conclusion, option B is correct.

The current through the television is 3.5 A.
<h3>Electrical power</h3>
Electrical power P = IV where I = electric current and V = voltage.
Since we require the current through the television with a power of 0.8 kW which uses 230 V mains supply, we make I subject of the formula.
<h3>The current </h3>
So, I = P/V
Given that P = 0.8 kW = 800 W and V = 230 V,
substituting the values of the variables into the equation, we have
I = P/V
I = 800 W/230 V
I = 3.48 A
I ≅ 3.5 A
So, the current through the television is 3.5 A.
