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
Answer:
7.5 J
Explanation:
To answer the question given above, we need to determine the energy that will bring about the speed of 1 m/s. This can be obtained as follow:
Mass (m) = 15 Kg
Velocity (v) = 1 m/s
Energy (E) =?
E = ½mv²
E = ½ × 15 × 1²
E = ½ × 15 × 1
E = ½ × 15
E = 7.5 J
Therefore, to change the speed to 1 m/s, the employee must do a work of 7.5 J.
The metal part of the torch is conductor and the handle maybe the insulattor
W=Fd
W=22,000N*(2,000m)
W=44,000,000J
Answer:
The maximum height is 10.0m
