Galileo discovered the planet Neptune. Is false, Galileo had been dead 200 years when Neptune was discovered.
Answer:
W = 0 J
Explanation:
Formula for work done is;
W = F × d
Where;
W is work done
F is Force
d is distance covered
What this means is that we will calculate the area under which the given times in the graph pass.
Thus;
At constant force of F = 40 N which falls in between distance of 0 m and 2m,
W1 = 40 × 2 = 80 J
At constant force of -20 n which will fall between distance of 2 m and 6 m which is 4m, we have;
W2 = -20 × 4
W2 = -80 J
Thus, total workdone is;
W = W1 + W2
W = 80 - 80
W = 0 J
Answer:
its frequency = 50 per second
Explanation:
Answer:
B) <u>The Gulf Stream carries warm water along the east coast, causing average temperatures to be warmer than they would be without the current. </u>
Explanation:
The east coast of the United States is affected mainly by the Gulf Stream current, which brings warm water from the tropics into higher latitudes. Because warmer water evaporates faster, putting more moisture into the air, the current serves to increase the humidity of the air along the coast.
