From what I know there are 2 types of compound verbs: more than one verb in a sentence or a verb that consists of 2+ words. The first type (2+ verbs in sentence) would be the sentence B (because it says "wrote" and "revised"). The second type (verb with 2 or more words) would be sentence A (because it says "working on")
Answer:
Explanation:
As we know that system of two boxes are moving on frictionless surface
So here if two boxes are considered as a system
then we have
Now since we know that both the boxes are moving together so force applied by first box on other box is given as
The arteries move blood away from the heart so therefore, the veins retract the blood throughout the body which eventually goes back to the heart and repeats itself nonstop
Answer:
4.14 m
Explanation:
In the last leg of the journey the ball covers 2 m in 2ms or 0.2 s .
Let in this last leg , u be the initial velocity.
s = ut + 1/2 g t²
2 = .2 u + .5 x 9.8 x .04
u = 9.02 m /s .
Let v be the final velocity in this leg
v² = u² + 2 g s
v² = (9.02)² + 2 x 9.8 x 2
= 81.36 +39.2
v = 10.97 m / s
Now consider the whole height from where the ball dropped . Let it be h.
Initial velocity u = 0
v² = u² +2gh
(10.97 )² = 2 x 9.8 h
h = 6.14 m
Height from window
= 6.14 - 2m
= 4.14 m
