The value of the inductor and resistor if they are in series then the resistor value is 10Ω and the inductor value is 0.5 H.
The network's admittance is approximately 0.0196 S.
a. To find the values of the inductor (L) and resistor (R) in a series network with an equivalent impedance of Zeq = (10 + j50)Ω at 100 rad/s, we can use the following relationships:
Zeq = R + jωL
where ω is the angular frequency, which is given as 100 rad/s.
Comparing the real and imaginary parts of the impedance, we have:
R = 10Ω (real part)
ωL = 50Ω (imaginary part)
To find the inductor value, we can rearrange the formula for the imaginary part:
L = 50Ω / 100 rad/s = 0.5 H
So, the resistor value is 10Ω and the inductor value is 0.5 H.
b. To find the admittance (Y) of the network, we can use the following formula:
Y = 1 / Zeq
First, find the magnitude of the impedance:
|Zeq| = √(10² + 50²) = √2600 = 50√(1.04) ≈ 51.02Ω
Now, calculate the admittance:
Y = 1 / 51.02Ω ≈ 0.0196 S
So, the network's admittance is approximately 0.0196 S.

The power generated by the engine was just 2.984 KW. How long would this engine have to run to produce 3.60 × 104 J of work?
1 watt = 1 joule/second
1 KW = 1,000 joule/second
Work = (power) x (time)
3.6 x 10⁴ J = (2,984 joules/second) x (time)
time = (3.6 x 10⁴J) / (2,984 J/s)
time = (36,000J) / (2,984 J/s)

Explain how the readings on both meters change when the environmental conditions change.
Help please :'0
Answer:
* Temperature changes
* Changes in the tension
* Errors in the meter marks
Explanation:
When we are using several meters to make a measurement we have several aspects that can cause the readings to differ.
* Temperature changes make the dilation between readings different, at higher temperatures the material of the meter expands and the reading decreases.
* Changes in the tension with which the meter is pulled to keep it straight, in general all materials bend under the action of gravity, so you have to pull them to make them straight, if the forces are different from the material is lengthened decide Young's modulus, inducing different readings
* Errors in the meter marks, especially in the initial part that is covered by a hook, different positions of the hook change the readings.
* Structural problems, such as rust, bends that create changes in the length of the meter material.

A vehicle starts to move from the rest gets an acceleration of 5 m/s2 within 2
seconds. Calculate the velocity and distance covered by the vehicle within the given time.
Answer:
I. Final velocity, V = 10m/s.
II. Distance, S = 10m.
Explanation:
Given the following data:
Acceleration = 5m/s²
Time = 2 seconds
Since the vehicle starts from rest, initial velocity = 0m/s
To find the final velocity, we would use the first equation of motion.
V = U + at
Substituting into the equation, we have
V = 0 + 5*2
V = 0 + 10
V = 10m/s.
Now, to find the distance covered, we would use the second equation of motion.
S = ut + ½at²
S = 0*2 + ½*5*2²
S = ½*5*4
S = 20/2
S = 10m
There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. If the brick is not moving on the scale, are the forces balanced or unbalanced?
Answer:
The forces are balanced
Explanation:
Since the brick is not moving on the scale, it means that the forces are balanced. An unbalanced force would only be present if there is motion of the brick. So, since the brick does not move, the net force on it is zero. Thus, the forces on it are balanced.

It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.
What is the electron affinity?The electron affinity of the neutral atom of the element can show indicate whether or not the element is going the make positive or negative ions. The higher the electron affinity is, the more the neutral atom wants to gain electrons.
The electron affinity for alkali metals and alkaline earth metals are low due to the fact that they are located on the left of the periodic table and only needs to loose 1 or 2 electrons to have a completed valence shell.
That means that they want to form cations (loose electrons). Halogens have a high electron affinity since they are located on the right of the periodic table and only have to gain 1 electron to get a completed valence electron configuration. That means that it forms anions.
Therefore, It depends on the location on the periodic table and if it is easier to loose are gain electrons to fill the valence electron shell.

The net force acting on the airplane if, An airplane is flying at 80 kilometers per hour when a strong tailwind, traveling in the same direction at 5 kilometers per hour is 85 km/hr so, option A is correct.
What is force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces.
For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Given:
An airplane is flying at 80 kilometers per hour when a strong tailwind, traveling in the same direction at 5 kilometers per hour,
Calculate the net force acting on the airplane as shown below,
The net force acting on the airplane = The velocity of the airplane + velocity of the wind (As they both are in the same direction)
The net force acting on the airplane = 80 km / hr + 5 km / hr
The net force acting on the airplane = 85 km / hr
Thus, the net force acting on the airplane is added.

Coulomb's Law says that the forces between any two charges depends directly on the size of the charges and inversely on the square of the distance between the charges. The correct option is D. A & B
Coulomb's lawFrom the question, we are to determine the correct option.
First, we will state Coulomb's law.
Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects
That is,
[tex]F \propto \frac{Q_{1} Q_{2} }{r^{2} } [/tex]
Where F is the electrical force
[tex]Q_{1} \ and \ Q_{2}[/tex] are the charges
r is the distance between the objects
From the law, we can observe that the forces depends directly on the size of the charges - Option A
and the forces also depends inversely on the square of the distance between the charges - Option B

A box can definitely not move on it's own unless an external force is applied i.e muscular force. If the applied force would have been less than the force of friction then the box would have never displaced. But, since the box is able to move, we can imply that, the applied force is greater than the frictonal force leading in the displacement of the box.

Sam, whose mass is 60 Kg, is riding on a 5.0 kg sled initially traveling at 8.0 m/s. He
brings the sled to a stop in 4.0 seconds. What amount of force is applied to the sled in
bringing it to a stop?
===============================================================
Explanation:
We'll need the acceleration first.
The initial speed (let's call that Vi) is 8.0 m/sThe final speed (Vf) is 0 m/s since Sam comes to a complete stop at the end.This happens over a duration of t = 4.0 secondsThe acceleration is equal to the change in speed over change in time
a = acceleration
a = (change in speed)/(change in time)
a = (Vf - Vi)/(4 seconds)
a = (0 - 8.0)/4
a = -8/4
a = -2
The acceleration is -2 m/s^2, meaning that Sam slows down by 2 m/s every second. Negative accelerations are often associated with slowing down. The term "deceleration" can be used here.
Here's a further break down of Sam's speeds at the four points of interest
At 0 seconds, he's going 8 m/sAt the 1 second mark, he's slowing down to 8-2 = 6 m/sAt the 2 second mark, he's now at 6-2 = 4 m/sAt the 3 second mark, he's at 4-2 = 2 m/sFinally, at the 4 second mark, he's at 2-2 = 0 m/sNext, we'll apply Newton's Second Law of motion
F = m*a
where,
F = force appliedm = massa = accelerationWe just found the acceleration, and the mass is fairly easy as all we need to do is add Sam's mass with the sled's mass to get 60+5.0 = 65 kg
So the force applied must be:
F = m*a
F = 65*(-2)
F = -130 newtons
This force is negative to indicate it's pushing against the sled's momentum to slow Sam down.
The magnitude of this force is |F| = |-130| = 130 newtons
