During convection of air currents, cool air sinks. <em>(b)</em>
Answer:
2880 N/c
Explanation:
Given that:
Charge per unit length ; λ = 4 * 10^-9
radius, r = 10
Radius, R = 0.5m
Using the relation :
2λr / 4πE0R²
Columb's constant, k = 1/4πE0 =. 9* 10^9Nm²/C²
Hence, we have :
2λrk/ R²
(2 * 4 * 10^-9 * 10 * 9 * 10^9) / 0.5^2
(720 ÷ 0.25)
= 2880 N/c
PART A)
Equivalent resistance in series is given as
now we have
PART B)
Here in order to find the current in the circuit we can use ohm's law
here we have
V = 24 Volts
R = 23 ohm
PART C)
Now in series circuit all branches of resistance connected to each other
so here no division of current
hence current in all resistors will be same
so we have
