Answer:
(a)
(b)
Explanation:
Given data
Area A=4.0 cm²=0.0004 m²
Electric permittivity ε=8.854×10⁻¹² farads/meter
Charge q=0.708 nC
To find
(a) Potential at distance=1.00mm
(b) Potential at distance=2.00mm
Solution
For (a) Potential at distance=1.00mm
First we need to find the capacitance
So
As we know that
So Electric potential is given as:
For (b) Potential at distance=2.00mm
First we need to find the capacitance
So
As we know that
So Electric potential is given as:
Answer:
inversely proportional to the temperature
Explanation:
Wein's displacement law states the wavelength at which Earth’s emitted radiation is maximum <u>is inversely proportional to the temperature</u> at which the wavelength of the Sun’s emitted radiation peaks.
λmax
where,
λmax is the maximum wavelength
b is a constant of proportionality called Wien's displacement constant (b = 2.897 × 10⁻³ m.K)
T is the absolute temperature in kelvins
