Answer:
intensity is 8.9 x W/m²
power is 11.3 x W
Explanation:
Given data
distance = 20 light year
power output = 4.00 x 10^28
to find out
intensity of the starlight and the power of the starlight
solution
we know the intensity formula that is
intensity = power / area
so here power is 4.00 x 10^28 and area = 4π(20ly)²
intensity = 4.00 x 10^28 / (4π (20×9.46×10^15)²
intensity = 8.9 x
so intensity is 8.9 x W/m²
and
power is Intensity × Area
so power = 8.9 x × (π (6.37 × 10^6)²
power = 11.3 x
so power is 11.3 x W
Answer:
I wish I knew the answer to that question
Answer:
the object melts so the size get smaller
Answer:
Explanation:
We have given the mass of the carbon =0.1 kg
Molar mass of the carbon =12 gram
Number of moles
We know that 1 mole of carbon contain
So atoms contained by 8.333 moles
In question it is given that each atom contain 6 proton so number of proton
Now we know that each proton contain positive charge of
So total charge
10 – 3 + 8 = 15 meters
10 + 3 + 8 = 21 meters
Her total traveled is 21 meters, displacement is 15 meters.
