Answer:
Explanation:
We are given that
d=0.23 mm=
Screen is placed from the slits at distance ,L=4.75 m
The bright interference fringes on the screen are separated by 1.56 cm.
1 m=100 cm
We have to find the wavelength of laser light.
We know that
Substitute the values
Answer:
The metal atoms in the wire can't move, but their outer electrons can. The force pushes those electrons and they move to further parts of the wire, trying to reach the other end. As the electrons move away, new electrons flow into the wire through the battery to take their place.
Explanation:
<span>Density is a physical
property which describes the mass of a substance per unit of volume of the
substance. It is expressed as Density = m / V. We calculate as follows:
Density = m / V
V = volume of a cube = (edge length) ^3 = (2.65 cm) ^3 = 18.61 cm^3
Density = 50.3 g / 18.61 cm^3 = 2.70 g / cm^3</span>
