What direct current in A will produce the same amount of thermal energy, in a particular resistor, as an alternating current tha

vodomira [7]

Answer:

$I_{rms}= 4.314 AExplanation:According to the definition of the root mean square value of current, the value of direct current which passes through the same circuit in which an alternating current is passing and producing same amount of heat as the direct current produced is called root mean square value of current. So, the relation between the root mean square value of current and the peak value of alternating current is given by [tex]I_{rms}=\frac{I_{0}}{\sqrt{2}}$

$I_{rms}=\frac{6.1}}{\sqrt{2}}$

[tex]I_{rms}= 4.314 A

M1u1 + m2u2 = m1v1 + m2v2
2 * 3 + 1 * 0 = 2 * 1 + 1 * v2
6 = 2 + v2
v2 = 6 - 2 = 4 m/s.

A swimmer swims 1000 m in the pool in 8.6 minutes. What was the average speed of the swimmer in m/s?

lawyer [7]

Speed = (distance covered) / (time to cover the distance)

Speed = (1,000 meters / 8.6 minutes) x (1 minute / 60 seconds) = 1.94 m/s
