Answer:
The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by <u>Ampere</u>
Explanation:
Two current carrying wires exert force on each other. This was discovered by Ampere. It is also known as Ampere's force law.
A current carrying wire produces magnetic field around it. Another current carrying wire kept nearby experiences magnetic force by the first one.
The force is given by:
where I₁ and I₂ are the currents in the two wires and r is the distance between them.
The force may be attractive or repulsive depending upon the direction of current flowing in the two wires.

Answer:
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas at STP = 1 atm
= final pressure of gas = 2.67 atm
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas at STP =
= final temperature of gas =
Now put all the given values in the above equation, we get:
Thus the final volume will be
Speed=Distance/Time. so you need to do distance/speed to get time. 3.84/4.32= .88888888889 seconds to get to his food bowl
