Household current in a circuit cannot generally exceed 15 for safety reasons. What is the maximum amount of charge taht could fl
1 answer:
The current I is defined as the amount of charge Q flowing through a certain point in a time t:
which can be rewritten as
so, by using this formula we can calculate the maximum amount of charge that can flow in the circuit. In fact, the maximum current is I=15 A, while the time is
so the maximum amount of charge is
which can be rewritten as

Answer:
The velocity of the players will be <u>2.88 m/s</u> in the <u>east</u> direction.
Explanation:
Let 'v' be the velocity of the players after collision.
Consider the east direction as positive direction.
Given:
Mass of the first player is, kg
Initial velocity of the first player is, m/s
Mass of the second player is, kg
Initial velocity of the second player is, m/s
In order to solve this problem we use the law of conservation of momentum which says that the total momentum must be conserved before and after the collision. So we can write:
Solving for v, we get:
Therefore, their velocity after the collision is 2.88 m/s.
The sign of the velocity after collision is positive. So, the players will move in the east direction only after collision.
