Answer: 9x10-3ms-1 -- A
Explanation:
Given wavelength λ = 505nm
1nm= 10^9m
505nm = 5.05 x10 ^-7m
and speed of light, c is 3.8 x 10^ 8
frequency = ?
Using frequency = speed of light / wavelength
f = c/λ
Frequency , f= 3.8 x10^8m/s/ 5.05 x10 ^-7m
=5.94 x 10 ^14 s⁻1
Also Energy = hv
where h =Planck constant = 6.626 x10 ^ -34 J.s
v= frequency =5.94 x 10 ^14 s⁻1
Energy = 6.636 x10 ^ -34 J.s x5.94 x 10 ^14 s⁻1
= 3.935 x 10 ^-19J
Given
9.5×10 −12 g as the mass of the bacterium,
changing to kg
1000g= 1kg
9.5×10 −12 g = 9.5×10 −15kg
to find the velocity
Energy = 1/2mv² = E=1/2mv²
v=
=
v =0.009099= 9x10-3ms-1
<span>High latitudes and altitudes are associated with permafrost. These areas provide the lengthy cold conditions that support permafrost development. Permafrost is soil, rock or sediment that is frozen for more than two consecutive years and is not found in warmer climates.</span>
Answer:
C. Somewhere in an expanding Universe, but not in any special part of it.
Explanation:
The Universe is constantly expanding so their is no exact location or pinpoint where you could call our current location or any location for that manner. You may be able to calculate how far we are from other galaxies and constallations but you cannot calculate how big the universe is.
