Click the ask a question button or answer button then at the bottom above the keyboard there are two little icons. A camera lens and a Mountain View. If you click the camera lens you can take a picture to post and if you click the Mountain View it will give you the option to post a picture from your photos.
I belive in circular motion but could double check:).
Answer:
Explanation:
when the surface is super smooth, the light reflects in all the same. which makes a good reflection. Like how a very calm lake can look like a mirror. the water gets very very smooth. or a mirror is very smooth too. If the surface reflects like more randomly.. like when a lake is rough or wind is blowing over it .. and there a small waves it's not a good "even" reflection.
Answer:
Explanation:
Given
Initial speed is u=V
Maximum height of Pebble is H
Deriving maximum height of Pebble and considering motion in vertical direction
where v=final velocity
u=initial velocity
a=acceleration
s=Displacement
Final velocity will be zero at maximum height
i.e. maximum height is dependent on square of initial velocity
for twice the height
on comparing
Answer:
64.10937 N
Explanation:
s = Displacement
v = Velocity
F = Force
Converting hp to W
Work
Power
Now
So,
The friction force acting on the van is 64.10937 N
