A resistor, inductor, and capacitor are connected in series, each with effective (rms) voltage of 65 V, 140 V, and 80 V respecti

Morgarella [4.7K]

Answer:

The value of the effective (rms) voltage of the applied source in the circuit is 132 V

Explanation:

Given;

effective (rms) voltage of the resistor, $V_R$ = 65 V

effective (rms) voltage of the inductor, $V_L$ = 140 V

effective (rms) voltage of the capacitor, $V_C$ = 80 V

Determine the value of the effective (rms) voltage of the applied source in the circuit;

$V= \sqrt{V_R^2 + (V_L^2-V_C^2} )\\\\V= \sqrt{65^2 + (140^2-80^2} )\\\\V = \sqrt{4225+ 13200} \\\\V = \sqrt{17425} \\\\V = 132 \ V$

Therefore, the value of the effective (rms) voltage of the applied source in the circuit is 132 V.

A car is traveling with an initial velocity of 15 m/s when the driver decides to go faster by accelerating at 5 m/s squared for

tiny-mole [99]

Answer:

x = 400 [m]

Explanation:

To solve this problem we must use the following kinematics equations, first, we find the final speed, and then we proceed to find the distance traveled.

$v_{f}=v_{i} +(a*t)\\$

where:

Vf = final velocity [m/s]

Vi = initial velocity = 15 [m/s]

a = acceleration = 5 [m/s^2]

t = time = 10 [s]

Note: the positive sign in the Equation indicates that the car is accelerating, i.e. its speed is increasing.

<u>Now replacing</u>

Vf = 15 + (5*10)

Vf = 65 [m/s]

Now using the second equation:

$v_{f} ^{2}= v_{i} ^{2}+(2*a*x)$

where:

x = distance traveled [m]

x = (65^2 - 15^2)/ (2*5)

x = 400 [m]

A particle of mass 6.3 x 10-8kg and charge 7.1 muC is traveling due east. It enters perpendicularly a magnetic field whose magni

ASHA 777 [7]

Answer:

t=0.016s

Explanation:

we can use

$\frac{v}{r}=\omega=\frac{qB}{m}=\frac{7.1*10^{-6}C*1.7T}{6.3*10^{-8}kg}=191.58s^{-1}$

the time that the particle is in the magnetic field is one half oa period. Hence

$t=\frac{T}{2}=\frac{\pi}{\omega}=0.016s$

I hope this is useful for you

What is science and why do we study science and what are the benefits we are going to get from it ?

Nina [5.8K]

Answer:

science is define as the study of physics, chemistry, biology, geology and astronomy. science is very important in our daily life.we study science for knowing the knowledge about biological and chemical and many other aspects.without science it is impossible to live our daily life.science is used in each and every steps.

Explanation:

There are many more benefits that we are getting and going to get . Science has already discovered many things ,that we didn't expect efore.And also in progress to discover new things.Science has developed a new type of antivirus that protect us from different virus.Has made different medicine that recover a people. So it is very useful in our life.
