Answer: A. FW = 20N x sin60°
Explanation: This is because resolution of the forces is taking along the horizontal plane.
Answer:
d. light microscopy allows one to view dynamic processes in living cells.
Explanation:
One advantage of light microscopy over transmission electron microscopy is that light microscopy allows one to view dynamic processes in living cells.
Electron microscope differ from the light microscope because electron micoscope produce the image of the specimen using electron beam and not light. Electron microscopy samples must be kept in vacuum, this means live cells can not be imaged.
Answer:
d = 450m
Explanation:
we know that:
V = d/t
where V is the velocity, d the distance and t the time.
so:
the turtle run at 0.9m/s a distance of 45m:
replacing v by 0.9 m/s and d by 45 m, we get:
V = d/t
0.9 = 45/t
solving for t:
t = 45/09 = 50 s
Now, using the same equation, the time that the turtle takes to travel 45 meters and the velocity of the rabbit, we get:
V = d/t
(9) = d/(50)
Solving for d:
d = 9*50 = 450m
it means that the rabbit travel 450m at the same time that the turtle travel 45m.
Answer:
B) 2.45 m/s^2 ( not sure i just search it )
Answer:
36.408cm3
Explanation:
Since we acknowledge that density is d= m/v, once we switch it up to maintain v as the number to be found it will change to v=m/d. Therefore, 275.32/7.562 is 36.408 and the unit is cm cube!
Hope that helped!!
