Answer:
a. Relative humidity increases: a decrease in temperature without a change in the amount of water vapor in the atmosphere.
Explanation:
Colder air requires less humidity to saturate compared to warmer air. Therefore, the relative humidity depends on the air temperature. If the temperature drops and the water vapor content remains the same, relative humidity increases. If the temperature increases and the water vapor content remains the same, relative humidity decreases. Additionally, a greater amount of water vapor in the air increases the relative humudity.
Answer:
The time constants 30 seconds and the can form an RC Charging circuit.
Explanation:
Time constant, τ, is measured in terms of τ = R x C, in seconds, where R is the value of the resistor in ohms and C is the value of the capacitor in Farads
If R = 150 kΩ = 150000Ω
and C = 200 μF = 0.0002 F
τ = 150,000 × 0.0002
<u>= 30 seconds.</u>
A capacitor, (C) connected in series with a resistor, (R) forms a RC Charging Circuit connected across a DC battery supply (Vs) via a mechanical switch, with transient time (time required to charge capacitor) = 5τ
Answer:
40,000N of force
Explanation:
The formula for force is F=ma. If we plug in the values, F=(20,000kg)(2m/s^2).
Answer:
(a) q=3.07 nC
(b) σ=17 nC/m²
Explanation:
Given data
Radius r=0.12m
Potential V=230 V
To find
(a) Charge q
(b) Charge density σ
Solution
For Part (a)
As we know that potential is:

Substitute the given values

For Part (b)
The charge density is given by:
σ=q/(4πr²)
Substitute the given values and value of q to find charge density
So

σ=17 nC/m²
Explanation:
i expected to use Stefan's law of heat exchange but the value you gave aren't conclusive.
I should say that the temperature of the star should be close to that of the sun because of the similarity in the intensity curves
