12N to the Right, i got it right!!!
Answer:
4.3 m/s² ( approx )
Explanation:
Velocity of local elevator with respect to express elevator initially is 2.1 mps
After 2.7 seconds , the gap between them is
2.7 x 2.1 = 5.67 m
The express elevator begins with acceleration . At the time of catching up
velocity of local with respect to express is - 9.5 m /s .That means velocity of
express with respect to local will be 9.5 m/s .
Relative velocity of express is 9.5 m/s
Absolute velocity of express is 9.5 + 2.1 = 11.6 m/s
Acceleration of express = change in velocity / time
= ( 11.6 -0)/ 2.7 = 4.3 m/s² ( approx )

Question: <span>Where might water be found on the moon?
Answer: Near The Poles (C)
Reason: Water is most likely to be discovered near the poles. The South pole is the most likely one.
Hope This Helps!

Because a Btu is so small, energy is usually measured in millions of Btus. 1 Btu = the amount of energy required to increase the temperature of one pound of water (which is equivalent to one pint) by one degree Fahrenheit. This is roughly the heat produced from burning one match.

Answer:
100 W
Explanation:
The power can be defined as energy change / time taken
Or
Energy used/time taken
So in this case you get,
Power = 2500/25 = 100 W
