Answer:
343/440
Explanation:
Recall that v=d/t
Now, this is the same thing.
Frequency is 1/T and wavelength is the distance travelled in one period.
So Vs=f*λ
(the greek letter is used as the symbol of wavelength; it's arbitrary)
It will move in the direction you pushed it, but it will go at a certain velocity
Answer:
1.8 m/s
Explanation:
here's the solution : -
momentum = mass × velocity
=》18 × 0.1
=》1.8 m/s
The answer is C hope this helps <span />
Answer:
1/f = 1/o + 1 /i thin lens equation
1 / i = 1/f - 1/o = (o - f) / (o f) rearranging
or i = o f / (o - f) for the image distance
This image will be positive (real) with values given
m = -i / o magnification
m = - f / (o - f) shows m is negative and the image inverted
Also, since o here is large m will be small and the image is small
I think they mean A as the right answer
Different texts use different terms but here i is image distance and o the object distance
