Answer:
0.003181 radians
0.003005 radians
Explanation:
Number of slits = 140 /cm
λ = Wavelength = 434 nm = 434×10⁻⁹ m
m = 3 Third order spectrum
Space between slits

Now,

0.003181 radians
When λ = 410 nm = 410×10⁻⁹ m

0.003005 radians
Answer:
i think rocks towards is correct answer
Answer : Option D) 90°N and 90°S
Explanation : The latitudes which are given in the options are the angle to be measured in the direction of north and south respectively taking equator as the central line.
When it is 90°N and 90°S it means it forms an right angle and faces towards north and south respectively with respect to the equator, so there are high chances of pointing towards the Arctic and Antarctic regions respectively; therefore giving greater probability of finding glaciers.
Work done = force x distance
Work done = 50 x 2
Work done = 100J
Answer:
vf=at+v0. vf=0
-v0=at
t=-v0/a=(-27m/s)/(-8m/s^2)=3.4s
