Answer:
Let d be the density of the water (1000 kg / m^3 eq to 1 gm / cm^3)
P = d g h for the pressure due to a column at the bottom of the column.
P = 1000 kg / m^3 * 10 m/s^2 * 10 m = 10^5 kg / m * s^2 = 10^5 N/m
Answer:
Atomic size gradually decreases from left to right across a period of elements.
Explanation:
This is because, within a period or family of elements, all electrons are added to the same shell. However, at the same time, protons are being added to the nucleus, making it more positively charged.
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
