Answer:
a) 0.81 A
b) 0.33 A , 0.48 A
c) 10 Volts , 10 volts
Explanation:
= 30 Ω
= 21 Ω
= Voltage of the battery = 10 Volts
a)
Parallel combination of resistance is given as
Ω
= Total current flowing through the circuit
Total current flowing through the circuit is given as
A
b)
In parallel, Voltage remain same.
= Potential difference across R₁ = 10 Volts
= Potential difference across R₂ = 10 Volts
Current flowing through individual resistors is given as
A
A
c)
In parallel, Voltage remain same, hence
= = 10 Volts
Answer:
Her final velocity is 46 m/s :-)
Explanation:
-- If velocity is constant, then there is no net force
on the chair.
-- If there is no net force on the chair, then friction
must exactly balance out your push.
-- The force of friction is exactly equal in magnitude
to your push, and in exactly the opposite direction.
