Answer:
240 Ω
Explanation:
Resistance: This can be defined as the opposition to the flow of current in an electric field. The S.I unit of resistance is ohms (Ω).
The expression for resistance power and voltage is give as,
P = V²/R.......................... Equation 1
Where P = Power, V = Voltage, R = Resistance
Making R the subject of the equation,
R = V²/P.................... Equation 2
Given: V = 120 V, P = 60 W.
Substitute into equation 2
R = 120²/60
R = 240 Ω
Hence the resistance of the bulb = 240 Ω
Answer:
fr = 514.5 N, This force has the opposite direction to the applied force.
Explanation:
Let's propose the solution of the problem using Newton's Second Law, we place a reference frame with the horizontal x-axis
Y axis
N- W = 0
N = W
X axis
F -fr = m a
the friction force has the expression
fr = μ N
fr = μ mg
fr = 0.35 150 9.8
fr = 514.5 N
This force has the opposite direction to the applied force.
The student's answer is incorrect because the friction coefficient must be multiplied by the normal
