Answer:
3 ohm
Explanation:
Resistance = Voltage/Current
= 6.0/2
= <u>3</u><u> </u><u>o</u><u>h</u><u>m</u>
C) both moving and non-moving objects
As, it is same as the Newton's first law motion
Answer:
The trade winds, the prevailing westerlies, the polar easterlies.
Explanation:
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10). Fig. 3.10 only shows the circulation cells and winds in the Northern Hemisphere
The work done is 315 J
Explanation:
The graph is missing: find it in attachment.
The work done by a variable force is given by
where
F(x) is the magnitude of the force
x is the position
On a force vs position graph, the work done is equivalent to the area under the graph. Therefore, in order to find the work done as the block moves from x = 0 to x = 8.0 m, we have to calculate the area under the graph between these two points.
Each square corresponds (vertically) to 45 N, so the area of the first trapezium between x = 0 and x = 4.0 m is
Then we have to find the area of the triangle between x = 6.0 m and x = 8.0 m:
Therefore, the total area (and the work done) is
