First, find the work done. W = f*d, so 160 N * 1 m = 160 J. Then divide the work by the time to get the power. P = W/t. P = 160 J / 0.5 s = 320 W.
The answer is 320 W. Hope this helps, and have a great day! :)

B)direct current </span>
Answer:
B
Explanation:
Water level remains unchanged
The first thing to realize is that the buoyancy force is the same as, or equal to the weight of the wood, this same force is also the same as or equal to the weight of the water displaced by the wood. In the two cases, the weight of the wood will be unaffected nonetheless, and thus the water level will remain the same.
Therefore, the answer is B, the water level remains unchanged.
Answer:
- Peat soil
- Loamy soil
- Clay soil
Explanation:
Peat soil is dark, highly decomposed organic matter found in soil.
Loamy soil is a mixture of materials that holds moisture and drains well and also contains coarse grains and allows water to drain quickly.
Clay soil contains medium grains and retains water. Also it contains fine grains and has little space for water.
Answer:
The object has 1250 Joules of Kinetic Energy.
Explanation:
Kinetic Energy = 
mass*velocity²
KE = mv²
KE = (100kg)(5m/s)²
KE = (100kg)(25m/s²)
KE = 1250
KE = 1250J
