Answer:
820 nm
Explanation:
We are given that
Wavelength=
For first minimum therefore
m=0
We know that for destructive interference
Substitute the values
Hence, the distance between two slits that produces the first minimum=820 nm
Answer:
61.0168 g/mol Explanation:
Answer:
zero
Explanation:
For a solid conducting sphere, charges are present on the surface of the sphere due to a phenomenon known as electrostatic sheilding. This affects the charge present in the body and makes it zero. However, the electrostatic potential appears to be equal to the whole present point that shows on the surface. The surface of a spherical conducting solid sphere is known as an equipotential surface. Thus, the potential difference between the two opposite points on the surface of the sphere will also be zero.
<u>Answer</u>
C.39.2 kPa
<u>Explanation</u>
The pressure in liquids depend on the depth or what we call the liquid column(h), the density of the liquid(σ) and the the acceleration due to gravity(g).
h = 4.00 m
σ = 1000 Kg/m³
g = 9.8m/s²
Pressure Is given by;
P = σgh
= 1000 × 9.8 × 4
= 39200 Pa
=39.2 KPa
