Earth distance to the Sun is about 40 times the Moon's distance from earth.
<u>Explanation:</u>
- The Earth's distance from the Sun is about 93 million miles. When it expressed in Km, it is 150 million Km.
- The Moon's distance from Earth is 238,855 miles. When it is 40 times then it will approximately equal to 93 million miles.
- The Sun's distance from Venus is 67.237 million miles. The Sun's distance from mercury is 35.832 million miles.
An electron that is far away from the nucleus have higher energy than an electron near the nucleus. Nucleus are positively charged and those electrons near it get attracted; those electrons gain kinetic energy hence reducing their internal energy. The electrons far from nucleus have low kinetic energy hence more internal energy.
Answer:
0.00915 m
Explanation:
= Wavelength of light = 610 nm
L = Distance of slit to screen = 1.5 m
a = Slit gap = 0.2 mm
Width of central maximum is given by
The width of the central maximum is 0.00915 m
Answer:
The width is 
Explanation:
From the question we are told that
The wavelength is 
The width of the slit is 
The distance of the screen is 
Generally the central maximum is mathematically represented as
Here y is the width of the first order maxima which is mathematically represented as
substituting values
So
