Given that,
Current = ∞
We know that,
Ohm's law :
Ohm's law is defined as,
The voltage of the circuit is directly proportional to the current of the circuit.
Or,
The voltage of the circuit is equal to the product of current and resistance.
In mathematically,
Where, V = voltage
I = current
R = resistance
According to ohm's law,
The current in the circuit is
If the current is very less then the resistance will be infinity.
If the is reach to infinity then the resistance will be very low.
Hence, The resistance becomes very low.
Answer
given.
Mass of big fish = 15 Kg
speed of big fish = 1.10 m/s
mass of the small fish = 4.50 Kg
speed of the fish after eating small fish =?
a) using conservation of momentum
m₁v₁ + m₂v₂ = (m₁+m₂) V
15 x 1.10 + 4.50 x 0 = (15 + 4.5)V
16.5 = 19.5 V
V = 0.846 m/s
b) Kinetic energy before collision
KE₁ = 9.075 J
Kinetic energy after collision
KE₂ = 6.98 J
Change in KE = 6.98 - 9.075 = -2.096 J
hence,
mechanical energy was dissipated during this meal = -2.096 J
