A series RCL circuit consists of a 50 Ω resistor, 500 Ω capacitor, and a 500 Ω inductor. What is the angle of impedance?

lbvjy [14]

Answer:

Zero

Explanation:

here, the inductive reactance and the capacitive reactance is same, so this is the condition for resonance.

In the condition for resonance,

the circuit and the voltage in the circuit is in the same phase and the impedance of the circuit is minimum which is equal to the resistance of the circuit.

The phase angle is given by

$tan\phi =\frac{X_{L}-X_{C}}{R}$

A car has a mass of 850 kg. By pushing on the car, Evan increases its speed

Dmitry_Shevchenko [17]

Answer:

I=1,2•10³ kg•m/s

Explanation:

v¹=3.5m/s

vf=5m/s

v=5-3.5=1.5m/s

I=p

I=mv=850•1.5=1275 kg•m/s=1,2•10³ kg•m/s

A 1200-kg car pushes a 2100-kg truck that has a dead battery to the right. When the driver steps on the accelerator, the drive w

zhannawk [14.2K]

Answer:4500 N

Explanation:

Given

mass of truck $(m_t)=2100 kg$

mass of car $(m_c)=1200 kg$

as the car push the ground with a force of 4500 N so the force on the truck should also be 4500 N as they all the force is transmitted to push the truck

and their acceleration is

$a=\frac{4500}{1200+2100}=1.36 m/s^2$
