Answers
Current is measured by placing the red plug into the 10 ADC port. So the correct answer is b. 10 ADC
To measure current, you need to Turn off the power to the circuit you want to measure. Set your multimeter to the appropriate current range (e.g., mA or A). Insert the red plug into the 10 ADC port on the multimeter. Insert the black plug into the COM port. Connect the multimeter in series with the circuit, meaning you need to break the circuit and connect the multimeter's probes between the two open points. Turn on the power to the circuit, and read the current value displayed on the multimeter.
The correct answer is b. 10 ADC

Explanation:
a 5.00 N salmon named sammy, swims 20 M upstream against a current that provides a resistance of 1.50 N. This portion of the stream rises at an angle 10 degrees with respect to the horizontal.
a) how much work is done by the sammy against the current?
b) what is the gain in PE by sammy?
c) what is the total work that must be done by sammy?
d) if sammy takes 40 S to swim the distance, what power does sammy have to exert to do so?
Answers
a) 67.96 J work is done by the Sammy against the current.
b) 3.46 m is the gain in PE by Sammy.
c) 85.06 J is the total work that must be done by Sammy.
d) If Sammy takes 40 S to swim the distance, 85 power does sammy have to exert to do so.
a) The work done by Sammy against the current is given by the formula:
Work = force × distance × cos(theta)
where force is the net force acting on the salmon, distance is the distance travelled by the salmon, theta is the angle between the force and the direction of motion.
Here, the net force acting on Sammy is:
force = 5.00 N - 1.50 N = 3.50 N
The distance travelled by Sammy is 20 m. The angle between the force and the direction of motion is 10 degrees.
Therefore, the work done by Sammy against the current is:
Work = (3.50 N) × (20 m) × cos(10 degrees)
= 67.96 J (Joules)
b) The gain in potential energy by Sammy is given by the formula:
PE = mgh
where m is the mass of the salmon, g is the acceleration due to gravity, and h is the height gained by Sammy.
Here, the height gained by Sammy is the vertical distance travelled while swimming upstream against the current. This distance is given by:
h = distance × sin(theta)
= 20 m × sin(10 degrees)
= 3.46 m
Therefore, the gain in potential energy by Sammy is:
PE = (5.00 N ÷ 9.81 m/s^2) × (3.46 m) × 9.81 m/s^2
= 17.10 J (Joules)
c) The total work that must be done by Sammy is the sum of the work done against the current and the gain in potential energy:
Total work = Work against current + PE gain
= 67.96 J + 17.10 J
= 85.06 J (Joules)
d) The power that Sammy must exert to swim upstream against the current is given by the formula:
Power = work ÷ time
where work is the total work done by Sammy, and time is the time taken to swim the distance.
Here, the total work done by Sammy is 85.

Answers
(a) The impulse reaction of the gadget is h(n) = δ(n+1) + δ(n-1). (b) The system is causal due to the fact the output simplest relies upon present and beyond inputs, x(n+1) and x(n-1), respectively. (c) The system is linear because it satisfies the homes of superposition and homogeneity.
(d) This is an IIR (Infinite Impulse Response) filter out because the output relies upon beyond inputs. (e) The frequency response of the machine is H(z) = \(z^(-1) + z\). (f) The device is BIBO strong considering its miles are linear and causal, and its impulse response is finite, ensuring bounded output for bounded enter.
(a) To discover the impulse reaction of the gadget, we want to enter an impulse signal. An impulse signal is represented as δ(n), that is 1 at n = 0 and 0 for all different values of n.
Let's alternative δ(n) into the given equation:
y(n) = x(n+1) + x(n-1)
For n = 0:
y(0) = x(1) + x(-1)
For n = 1:
y(1) = x(2) + x(0)
For n = -1:
y(-1) = x(0) + x(-2)
For n ≠ 0, 1, -1, y(n) = 0 considering the fact that x(n) = 0.
So, the impulse reaction of the gadget is:
h(n) = δ(n+1) + δ(n-1)
(b) The machine is causal if the output y(n) relies upon only on the present and beyond inputs x(n), x(n-1), x(n-2), and so forth. In this case, due to the fact that y(n) simplest depends on x(n+1) and x(n-1), it does not depend on future inputs. Therefore, the machine is causal.
(c) The system is linear if it satisfies the properties of superposition and homogeneity. Let's confirm these houses:
Superposition:
For two inputs \(x1(n)\)and \(x2(n)\) their corresponding outputs \(y1(n)\) , \(y2(n)\), we've got:
\(y1(n) = x1(n+1) + x1(n-1)\)
\(y2(n) = x2(n+1) + x2(n-1)\)
Now, allow's apply the machine to the linear aggregate of inputs:
\(y(n) = ax1(n) + bx2(n)\)
=\(a(x1(n+1) + x1(n-1)) + b(x2(n+1) + x2(n-1))\)
= \(ax1(n+1) + ax1(n-1) + bx2(n+1) + bx2(n-1)\)
This fits the output received when the system is carried out to the linear mixture of the person inputs. Therefore, the device is linear.
(d) This is an IIR (Infinite Impulse Response) clear out due to the fact the output depends on each contemporary and past input, as visible inside the equation y(n) = x(n+1) + x(n-1).
(e) To locate the frequency response, we will take the Z-remodel of the gadget's impulse response. Applying the Z-transform to the impulse response h(n) = δ(n+1) + δ(n-1), we get:
H(z) =\(Zh(n) = z^(-1) + z\)
The frequency response of the device is the Z-transform of the impulse reaction.
(f) BIBO (Bounded-Input Bounded-Output) stability refers to the belongings of the device to produce bounded output for any bounded input. In this example, because the system is linear and causal, and the impulse reaction is finite, the device is BIBO stable.

Carbon dioxide undergoes a phase change called sublimation, how does a single molecule of carbon dioxide change as a result of this process in terms of its energy and physical characteristics? a. There is a physical change from a gas to a liquid; energy is released into the environment reducing the molecular movement. b. There is a physical change from the solid state to a gas state where energy between the molecules increases. c. There is a chemical change between the carbona nd oxygen resulting int he formation of oxygen gas which has more energy d. There is a chemical change as the carbon dioxide is transferred from a liquid to a solid reducing the amount of energy
Answers
The correct answer is(b). There is a physical change from the solid state to a gas state where energy between the molecules increases.
What is the process of sublimation in carbon dioxide?During sublimation, carbon dioxide transitions directly from the solid state (dry ice) to the gas state without passing through the liquid phase. In this process, individual molecules of carbon dioxide gain energy from the surroundings, leading to an increase in their kinetic energy and molecular movement.
As a result, the carbon dioxide molecules separate from each other and form a gas. This phase change is considered a physical change rather than a chemical change since the chemical composition of carbon dioxide remains the same throughout the process.
Therefore, the sublimation of carbon dioxide results in a physical change where the molecules transition from the solid state to the gas state, gaining energy and increasing their molecular movement.

3. How does the separation between the wave sources affect the interference pattern?
Answers
The separation between wave sources affects the interference pattern by changing the phase difference between the waves arriving at a particular point.
The interference pattern is a result of the superposition of waves from multiple sources. When the sources are close together, the waves interfere constructively and destructively in a complex pattern. As the sources are moved further apart, the interference pattern becomes more spread out, with fewer and broader maxima and minima.
Eventually, when the sources are far apart, the interference pattern disappears, and the waves can be treated as independent. The distance between the sources affects the phase difference between the waves arriving at a particular point, which determines whether they interfere constructively or destructively. Therefore, as the separation between sources increases, the phase difference between the waves decreases, resulting in a less pronounced interference pattern

a ladder whose length is 12 meters and whose mass is 45 kg rests against a building. its upper end is 9.3 meters above the ground. the center of mass of the ladder is one-third of the way up the ladder. a firefighter of mass 72 kg climbs halfway up the ladder. you may assume that the verticle side of the building is frictionless. the ground is not frictionless. what forces are exerted on the ladder by the wall and by the ground
Answers
The forces exerted on the ladder by the wall and the ground is 937.2 N.
To calculate the wall's and the ground's pressures on the ladder, we need to consider the weight of the ladder and the firefighter.
The weight of the ladder can be calculated using the formula:
Weight = mass * gravity
Weight = 45 kg * 9.8 m/s² ≈ 441 N
The weight of the firefighter can be calculated in the same way:
Weight = mass * gravity
Weight = 72 kg * 9.8 m/s² = 705.6 N
The normal force exerted by the wall balances the weight of the ladder and the firefighter. Since the ladder is in equilibrium, the normal force is equal to the combined weight:
Normal force (wall) = Weight of the ladder + Weight of the firefighter
Normal force (wall) = 441 N + 705.6 N = 1146.6 N
The normal force exerted by the ground supports the weight of the ladder and the firefighter. Since the center of mass is one-third of the way up the ladder, the normal force is distributed accordingly:
Normal force (ground) = (2/3) * Weight of the ladder + Weight of the firefighter
Normal force (ground) = (2/3) * 441 N + 705.6 N = 937.2 N
The frictional force opposes the tendency of motion along the ground. It depends on the coefficient of friction and the normal force. Without the coefficient of friction given, we cannot calculate the exact value of the frictional force.
Therefore, the ladder experiences a normal force from both the wall and the ground, while the ground also exerts a frictional force whose value requires the coefficient of friction.

at what part of an elliptical orbit does an earth satellite have the greatest speed? the least speed?
Answers
An elliptical orbit is an oval-shaped path that a satellite takes around its primary body, such as the Earth. The speed of a satellite in its orbit varies depending on its distance from the primary body, which changes throughout the elliptical orbit.
According to Kepler's laws of planetary motion, a satellite moves fastest when it is closest to the primary body, and slowest when it is farthest away. Therefore, an Earth satellite has the greatest speed at the point in its orbit called perigee, which is the point where it is closest to the Earth. At perigee, the satellite experiences the strongest gravitational pull from the Earth, which accelerates it and increases its speed.
Conversely, the satellite has the least speed at the point called apogee, which is the farthest point in its orbit from the Earth. At apogee, the satellite experiences the weakest gravitational pull from the Earth, which decelerates it and decreases its speed.
It's important to note that the speed of a satellite in orbit is also affected by other factors, such as the presence of other gravitational bodies and atmospheric drag. However, the varying distance from the primary body is the primary factor affecting the speed of a satellite in an elliptical orbit around the Earth.

Answers
Answer:
Resultant displacement is 29.2 km at north of west
Explanation:
To solve the problem, we have to use the rules of vector addition, resolving first each vector along the x- and y- direction.
Taking east as positive x direction and north as positive y- direction, we have:
- First displacement is 25.5 km east, therefore its components are
- Second displacement is 41.0 km northwest, so its components are
So, the components of the resultant displacement are
And so, the magnitude is calculated using Pythagorean's theorem:
And the direction is given by
Where the angle is measured from the west direction, since Rx is negative.
