The angle for the first minimum m=1
The width of the pattern=
Using moving water to produce electricity is an example of changing one form of energy into another form of energy.
Answer: The correct answer is "the same as the sum".
Explanation:
The expression for the equivalent resistance in the series combination of the circuit is as follows;
Here, R' is the equivalent resistance, are the resistances.
The expression for the equivalent resistance in the parallel combination of the circuit is as follows;
Here, R' is the equivalent resistance, are the resistances.
In the series combination of the circuit, the equivalent resistance is more than the equivalent resistance in the parallel combination of the circuit.
In the series combination of the circuit, the same amount of current flows across the resistance but the voltage is different across the resistances.
Therefore, for resistor in series, the equivalent resistance is the same as the sum.
Answer:
2.136 N-m
Explanation:
From the question,
Applying,
Toque = FL...................... Equation 1
Where F = Force applied to the the ball, L = Length of the forearm
From newton's second law of motion,
F = m(v-u)/t................. Equation 2
Where m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time.
Given: m = 0.140 kg, u = 0 m/s (from rest), v = 24 m/s, t = 0.425 s
Substitute into equation 2
F = 0.140(24-0)/0.425
F = 7.91 N.
Also Given: L = 0.270 m
Substitute into equation 1
Torque = 7.91×0.270
Torque = 2.136 N-m
