Answer: m= 35.6 kg
Explanation:
For finding the mass of the stone we have the formula
v=
Here, Tension= m*g = m*9.81
and linear mass density=
Linear mass density=
Linear mass density= 0.0127 kg/m
Velocity=
Velocity= 2 *
Velocity= 165.8 m/s
So putting all these values in equation we get
v=
165.8=
Solving we get
m= 35.58 kg
or m= 35.6 kg
Answer:
If R₂=25.78 ohm, then R₁=10.58 ohm
If R₂=10.57 then R₁=25.79 ohm
Explanation:
R₁ = Resistance of first resistor
R₂ = Resistance of second resistor
V = Voltage of battery = 12 V
I = Current = 0.33 A (series)
I = Current = 1.6 A (parallel)
In series
In parallel
Solving the above quadratic equation
∴ If R₂=25.78 ohm, then R₁=10.58 ohm
If R₂=10.57 then R₁=25.79 ohm
