Answer:
<u>4x </u><u> cm</u>
Explanation:
400nm = 400 x m
1m = 100 cm
400 x m = 400 x x 100 cm
ans : wavelength of light = <u>4x </u><u> cm</u>
Answer:
See below....the question is unclear....pick the answer you think they want
Explanation:
Car goes from 30 m/s to 24 m/s in 10 seconds
acceleration = change in velocity/change in time
= -6 m/s / 10 s = <u>- 3/5 m/s^2 </u>
<u />
<u />
The wording of the question is not very good.....perhaps they meant to say that after the 5 seconds the velocity is now 24 m/s ?
a1 *10 + a2 *5 = -6 m/s
( 6 m/s is the change in velocity from 30 to 24 m/s)
a1/a2 = 1.5 so a2 = a1/1.5 (substitute this in)
10 a1 + 5 ( a1/1.5) =-6
15 a1 + 5 a1 = -9
<u>a1 = - .45 m/s^2</u>
Answer:
Explanation:
It is given that,
The planet Mercury travels in an elliptical orbit with eccentricity 0.206, e = 0.206
The minimum distance from the sun,
The relation between the minimum and the maximum distance from the sun is given by :
a is the maximum distance from the sun
or
So, the maximum distance from the sun is . Hence, this is the required solution.
Humidity of air=heat not cold so 10%
