Answer:
2:5
Explanation:
We have the initial mass of the fish = 4.5kg
The mass of water intake = 40%of 4.5kg
= 0.40x4.5kg
= 1.8kg
The formula for conserving momentum
M1V1 = M2V2
M1 = mass of the puffer fish = 4.5kg
M2 = mass of the applied water = 1.8kg
V1 = velocity of the puffer fish
V2 = velocity of water
We are then to find v1/v2
V1/V2 = M2/M1
V1/V2 = 1.8/4.5
= 1/2.5
This is also 2/5
Therefore we have the ratio to be 2:5
Answer B would be the correct answer for the questions
<h2>
Answer: the object's ability to store charge</h2>
Explanation:
The capacitance is defined as the relationship between the electric charge of each conductor and the potential difference between them. That is, it is the capacity of a device to store electrical charge.
In other words:
It is the property that bodies have to maintain an electric charge.
Mathematically it is defined as:
where:
is the capacitance value of a capacitor. Its unit is Farad ; named in honor of the physicist Michael Faraday
is the electric charge of the conductor, measured in coulombs .
is the electric potential to which the conductor is located, measured in Volt.
The relationship between Voltage<span>, </span>Current<span> and </span>Resistance<span> forms the basis of Ohm’s law. In a linear circuit of fixed resistance, if we increase the voltage, the current goes up, and similarly, if we decrease the voltage, the current goes down. This means that if the voltage is high the current is high, and if the voltage is low the current is low.</span>
