The Sun is a star around which our planet Earth and other planets and satellites of our solar system revolve along specific orbits. Sun appears to be spherical in shape and consists of glowing hot gases. It contains mostly hydrogen and helium gases. The temperature of the gas mixture is extremely high.
Therefore, the Sun mostly composed of hydrogen and helium gases.
(Answer) B. Composition mostly hydrogen and helium gas, Mass 1.989 x 10^30 Kg

I think the right answer for this question is : 138 because the boy is just 15 year old but he has resting heart rate of 70
Answer:
t = 110.079 nm
Explanation:-
we know that
for constructive interference in thin film
2nt = (m + (1/2))λ
where, n is refractive index
for minimum thickness m =0
2nt = λ /2
thickness t = λ / 4n
Here
wavelength of light, λ = 612*10^{-9} m
refractive indices = 1.393

t = 110.03 nm
Answer:
Explanation:
Input work is the work done on a machine as the input force acts through the input distance. ... Output work is the work done by a machine as the output force acts through the output distance. The machine does to the object to increase the output distance.
