primary sex characteristics the development of breast in female
Power = (energy) / (time)
15 minutes = 900 seconds
Power = (2.5mJ) / (900 sec)
<em>Power = 0.00278 mWatts</em>
If your 'm' means 'Mega...', then power = 2,777.8 watts ... about the same as a hefty restaurant toaster, or home microwave oven when it's cooking.
A chemical reaction is <span>a process that involves rearrangement of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction.

Answer:
6052114.67492 m
Explanation:
v = Velocity of cosmic ray = 0.88c
c = Speed of light =
d = Width of Earth = Diameter of Earth =
When the cosmic ray is moving towards Earth then in the frame of the cosmic ray the width of the Earth appears smaller than the original
This happens due to length contraction
Length contraction is given by
The Earth's width is 6052114.67492 m
Contraction only occurs in the cosmic ray's frame of reference in the direction of the ray. But in perpendicular direction the width remains unchanged.
Hence, the width is
