Hi there!
Voltage in a series can be expressed by the following:
In words, the total voltage is equal to the sum of the individual voltage drops in a SERIES circuit.
We can solve for the total voltage:
B) at the poles of the magnet
Answer:
percentage by volume of the solute = 45%
Explanation:
The percentage by volume of the solute in a solution is the percentage of the volume of the solute as against the overall volume of the solution.
In this example,
volume of solution = 300mL
volume of solute = 135mL
% volume of solute = (volume of solute ÷ volume of solution) × 100
= (135 ÷ 300) × 100
= 0.45 × 100 = 45%
∴ percentage by volume of the solute = 45%
The μs between the clock and floor is 650(M*g) and the μk between the clock and the floor is 560(M*g)
Acceleration = (change in speed) / (time for the change)
Change in speed = (end speed) - (start speed)
Change in speed = (26 m/s) - (12 m/s) = 14 m/s
Time for the change = 6 s
Acceleration = (14 m/s) / (6 s)
Acceleration = (14/6) (m/s²)
<em>Acceleration = 2.33 m/s²</em>
