Answer:
a) 7.2*10^55
b) 1.2*10^29 kg
c) 3.2*10^11 m/s
Explanation:
Given a diameter of 10 km, that's a radius of 5 km.
We first attempt to find its mass number
A = (r/1.2*10^-15)³
A = (5/1.5*10^-15)³
A = 7.2*10^55
This gotten mass number is then multiplied by the mass of each neutron in the star. With each neutron being, 1.7*10^-27
M = 7.5*10^55 * 1.7*10^-27
M = 1.2*10^29 kg
And finally, using the formula
g = GM/r², we can find its acceleration due to gravity.
g = (6.67*10^-11 * 1.2*10^29) / 5000²
g = 8*10^18 / 2.5*10^7
g = 3.2*10^11 m/s
It allows the current flowing through it to be controlled. It allows it to flow and it can prevent it from flowing. This saves electricity.
Answer:
Explanation:
Given that
Wavelength
slit separation
slit screen distance
We know that for double slit the maxima condition is that
For small angle approximation,
Now
Again
Hence
A) seems more likely and work in unity.
