In this configuration, the two ideal op-amps and resistors work together to implement the specified summing function.
To implement the summing function v0 = v1 + 2v2 - 3v3 - 5v4 using two ideal op-amps and resistors, you can use a combination of a non-inverting summer and an inverting summer.
1. Connect the non-inverting inputs of both op-amps to the ground.
2. Connect the inverting inputs of both op-amps to a summing junction using resistors.
3. For the non-inverting summer (Op Amp 1), connect v1 and v2 to the summing junction using resistors R1 and R2 with the same resistance value. This will produce v1 + v2 at the output of Op-Amp 1.
4. For the inverting summer (Op Amp 2), connect v3 and v4 to the summing junction using resistors R3 and R4 with resistance values in the ratio of 3:5, respectively. This will produce -3v3 - 5v4 at the output of Op-Amp 2.
5. Finally, connect the outputs of both op-amps (Op Amp 1 and Op Amp 2) to another summing junction using equal-value resistors. This will result in the desired summing function v0 = v1 + 2v2 - 3v3 - 5v4 at the output.
In this configuration, the two ideal op-amps and resistors work together to implement the specified summing function.

if a person is 6.25 m away from a 60.0 w speaker, what is the sound level they are hearing?
(treat the speaker as a point source.)
Answer:
111dB
Explanation:
First, find the intensity of the sound using the formula I = Power / 4 x pi x radius ^2
So
60.0 / (4 x 3.14 (6.25)^2)
= 0.122
Then plug that into the equation to find sound level, which is 10log( I / Io)
Io being (1 x 10^-12)
So
10log(0.122 / 1 x 10^-12)
= 111dB

pls mark me brainliest
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.

Answer:
a) Yes because spiderman isn’t part of the system (the train), so he exerts an external force on the system, causing it to slow. The sign is negative because the train is slowing negative.
b) The train was initially moving, so it had kinetic energy, the energy of movement. There isn’t the same amount anymore because spiderman did work onto the train. Work is defined by the change of kinetic energy of the system, so the train didn’t have the same amount of that type of energy at the end.

Let the displacement function of a particle is x(t)=(20t^2-15t+200). Find the total displacement, instantaneous velocity and instantaneous acceleration
Answer:
A.) 39.5 m
B.) 0
C.) 60m/s^2
Explanation:
Given that a displacement function of a particle is x(t)=(20t^2-15t+200).
To Find the total displacement,
Reduce everything by dividing them by 5
X(t) = 4t^2 - 3t + 40 ...... (1)
For instantaneous velocity, differentiate x(t). That is,
dy/dt = 60t - 15 ...... (2)
But dy/dt = velocity.
If dy/dt = 0, then
60t - 15 = 0
60t = 15
t = 15/60
t = 0.25s
Substitutes t in equation (1)
Total displacement will be
X(t) = 4(0.25)^2 - 3(0.25) + 40
X(t) = 0.25 - 0.75 + 40
Total displacement = 39.5 m
To calculate instantaneous velocity, substitute t into equation (2)
V = 60 (0.25) - 15
V = 0.
and to find instantaneous acceleration, differentiate dv/dt
dv/dt = 60
Therefore, acceleration = 60 m/s^2

According to Newton’s law of universal gravitation, as the mass or one or both bodies increases, what happens to the force of attraction between the bodies?
force decreases
causes no change
force increases
Answer:
force increases
Explanation:
Newton's law of universal gravitation states that the force of attraction (gravity) acting between the Earth and all physical objects is directly proportional to the Earth's mass, directly proportional to the physical object's mass and inversely proportional to the square of the distance separating the Earth's center and that physical object.
According to Newton’s law of universal gravitation, as the mass or one or both bodies increases, the force of attraction between the bodies increases.
Mathematically, this is given by the Newton's Second Law of Motion;
Force = mass * acceleration.

Answer:
99 joules.
Explanation:
Let m denotes mass of the object and v denotes velocity.
If mass has units of kilograms and the velocity has units of meters per second then the kinetic energy has units of joules.
Kinetic energy is an energy possessed by a body in motion.
Mass (m) = 99 kg
Velocity (v) = 2 m/s
To find kinetic energy, use the following formula:
Kinetic energy = [tex]\frac{1}{2}mv^2=\frac{1}{2}(99)(2)=99[/tex] joules
Three identical resistors have an equivalent resistance 15.6 ohm when they are connected in series. What is the resistance for each resistor
Answer:
5.2 Ω.
Explanation:
What is the resistance for each resistor
Since the resistors are connected in series and each have resistance R, and their equivalent resistance is R' = 15.6 Ω.
Since they are connected in series, R' = R₁ + R₂ + R₃
Since R₁ = R₂ = R₃ = R
R' = R + R + R = 3R
R' = 3R
R = R'/3
R = 15.6 Ω/3
R = 5.2 Ω
So, the resistance of each resistor is 5.2 Ω.

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.

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)
time = 12.06 seconds
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.
