The payback period is the length of time it takes for a project to recoup its initial cost. To calculate the payback period, we need to determine how many years it will take for the cash inflows to equal the initial project cost.
How to calculate payback period?
In this case, the project cost is ETB 30,000 and the annual cash inflows are ETB 10,000.
Payback period = Project cost / Annual cash inflows
Payback period = 30000/10000
Payback period = 3 years
It will take 3 years for the project to recoup its initial cost of ETB 30,000 with annual cash inflows of ETB 10,000.

1. A steel container expands in volume 1% when the pressure with in it is increased by 70Mpa. At standard pressure, it holds 8kg of water; =1000kg/m3. For K=2.05Gpa, when it is filled, how many kilograms of water must be added to increase the pressure to 70Mpa (gage)?
0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).
Solving for how many kilograms of water must be added to increase the pressure to 70 Mpa (gage):To find the amount of water needed to increase the pressure to 70Mpa, we need to use the formula:
Change in volume = (Initial volume) x (Change in pressure)
Young's modulus
The initial volume of the container is 8 liters, since the container holds 8kg of water at standard pressure and the density of water is 1000 kg/m³.
So, change in volume = 8 x 10⁻³ m³
We know that the container expands by 1% when the pressure inside it is increased by 70 MPa, and we want to find the amount of water needed to increase the pressure to 70 MPa.
So, Change in pressure = 70 MPa
Young's modulus (K) = 2.05 GPa
Therefore, Change in volume = (8 x 10⁻³) x (70 / 2.05 x 10^9) = 2.68 x 10⁻⁵ m³
To find the amount of water needed to increase the pressure to 70 MPa, we need to multiply the change in volume by the density of water.
So, amount of water needed = (2.68 x 10⁻⁵) x (1000) = 0.268 kg
Therefore, 0.268 kg of water must be added to increase the pressure to 70 Mpa (gage).

The inner surface of the wall is at 11000C and the room temperature is 250C. The heat transfer coefficient from the outside wall surface to the air in the room is 17 W/m2K, and the resistant to heat flow of the air gap is 0. 16K/W.

What is the temperature at the outside surface of the wall?Determine the loss rate per square foot of the wall surface. Our refractor block brick's thermal resistance is equal to B divided by K. A times one. Thus, this is equal to 1.6 times one divided by 12.5 times 10 to the negative three. Our air gap contributes 0.16 K per W to our thermal resistance. We have three fire bricks as a result. Three divided by K gives us B. A thrice. This equals 0.3 times one divided by 1 25 times 10 to the negative three. Because of our plaster, four equals four divided by B divided by K.Four times our area is equal to 12 x 10 3 / 30.14 x 1 or 4 times our area. Furthermore, our thermal resistance is not equal to one divided by H but rather by A due to the heat transfer from the outside. This makes 1/7. The reason why adding R. One plus R.

What is transverse displacement?
Here given the data
Then the equation y(x,t)=Acos(kx−ωt)
speed (v) = 9.00 m/s
amplitude (A) = 9.00 × 10^−2 m
wavelength (λ ) = 0.480 m
We have to find out transverse displacement.
Here we know that.
v = angular frequency / wave number
also wave number = 2 / λ
= 2 / 0.480
= 13.0899
angular frequency = v x k
angular frequency = 9.00 × 13.0899
angular frequency = 117.8097 rad/sec
= 118 rad/sec
Therefore, the equation y(x,t)=Acos(kx−ωt)
y(x,t)=9.00 × 10^−2 cos(13.0899 x−118t)
If x =0 and and t = 0
Then, maximum y(x,t)= 9.00 × 10^−2 cos(13.0899 (0) − 118 (0))
= 9.00 × 10^−2 m
if x = 1.59 m and t = 0.150 s
Then,
y(x,t) = 9.00 × 10^−2 cos(13.0899 (1.59) −118(0.150) )
y(x,t) = 9.00 × 10^−2 × (0.99959)
y(x,t) = 0.089963 m

neglecting the size of the ball, determine the magnitude va of the basketball's initial velocity. (figure 1) express your answer to three significant figures and include the appropriate units.
The trajectory displayed is followed by a basketball as it is thrown at an initial speed of 8.5 m/s.
Explain about the initial velocity?Any object will accelerate as a result of forces acting on it. This acceleration causes a change in the object's velocity. The object's initial velocity is hence its speed prior to the change brought on by acceleration.
The time required is 3 seconds if the terminal velocity of the person is 10 meters per second and the acceleration is 2 meters per second. How fast did that person start moving? u= 10+6 = 16m/s.
When gravitational force is first exerted on an item, its initial velocity indicates how quickly it moves. The final velocity, on the other hand, is a vector number that gauges the speed and direction of a moving object after it has experienced its maximum acceleration.

given the wheelbase of the car 138.8 inches, trackwidth 75 inches and loads on tires as follows. determine the longitudinal cg location in inches measured from the front wheel,
Wheelbase, trackwidth, and tire load data can be used to determine the longitudinal CG location. The distance in inches between the center of gravity and the front wheel.
Wheelbase, trackwidth, and tire load data can be used to determine a car's longitudinal center of gravity (CG) location. The distance between the centers of the front and rear wheels is known as the wheelbase, while the distance between the left and right tire centerlines is known as the trackwidth. The amount of weight on each of the four tires that are in contact with the ground is known as the tire load. The entire weight of the vehicle is divided by the wheelbase and trackwidth, and the resulting number is multiplied by the wheelbase to determine the longitudinal center of gravity (CG) location. The resultant measurement, taken from the front wheel, is the longitudinal CG location in inches.

what is situations would it be possible to use a utp cable standard such as 1000base-cx instead of a fiber-optic cable standard such as 1000base-lx or 1000base-t?
If the 1000BASE-T Ethernet connection's allowed distance limitation is disregarded.
For infrastructure applications, Cat 5e utp cable models are created; they give the networks that use them the ability to send data securely, without packet loss, and without any speed loss during operations. Both specify Ethernet connection, but 1000BASE-T at 1 Gb/s. Additionally, both are made to operate on up to 100 meters of four-pair, 100 ohm-impedance twisted-pair cables. We can infer from this data that the transmission speed will decrease significantly if the 1000BASE-T Ethernet connection's permitted distance constraint is disregarded and the frames are sent across a 300 meter Cat5e cable segment. The transmission speed will decrease noticeably if the 1000BASE-T Ethernet connection's permitted distance limitation is disregarded and the frames are delivered over a 300-meter Cat5e cable segment.

Consider a simple pendulum and compute the magnitude of the restoring force if the mass of the pendulum is 2 kg and the length of the pendulum is 0.5 m. Assume the pendulum is at the surface of the earth at sea level.
The magnitude of the restoring force if the mass of the pendulum is 2 kg and the length of the pendulum is 0.5 m. The answer is ∣Fres ∣=9.81 sin θ Nm.
How to find out the pendulum is at the surface of the earth at sea level.?We are given:
g = 9.8 m/s ^2 - acceleration due gravity
m = 2 kg - mass of body attached on the string
l = 0.5 m - length of pendulum
Required.
We are asked to find the magnitude of the restoring force under given conditions.
Step2:
First, we need to consider a given situation. In our case, we have a simple pendulum with a mass of the pendulum that is 2 kg, and a length of the pendulum is 0.5 m. Important to emphasize is that the observed pendulum is at the surface of the earth at sea level.
The restoring force for the pendulum has the units of the moment (generally restoring force need not have units of force) and depends on the angle that the pendulum closes with the vertical.
∣Fres ∣=m g l sin θ
Step3:
Finally, we need to substitute known values into equation (1) and solve it.
Calculation method.
∣Fres ∣=m g l sin θ
= (2 kg) (9.80 m/s^2) (0.5 m) sin θ
=19.6 N (0.5m) sin θ
=9.80 sin θ N m
The magnitude of the restoring force is ∣Fres ∣=9.81 sin θ Nm

What is mean by JAVA?
Java is an object-oriented programming language used widely in creating applications for internet and web development. It was created in 1995 by Sun Microsystems, which was later acquired by Oracle. Java is a popular language because it is simple to learn and use, and it is secure, reliable and efficient. It also has a large library of existing code that can be reused, making development easier and faster. Java is an interpreted language, meaning that the code is compiled and interpreted by the Java Virtual Machine (JVM).
This makes Java applications more portable than other languages, since the code does not need to be recompiled for each platform.
