I need to find the Current Flow through each resistor in this Combo Circuit, so far I have gotten that the current total is .5A.
and the Resistance total is 10ohms.
Can anyone please help!
To find the current flow through each resistor in a combo circuit, you need to use Ohm's law and the principles of electrical circuits.
What is Combo Circuit?Ohm's law states that the current flowing through a circuit is directly proportional to the voltage applied and inversely proportional to the resistance of the circuit. This means that the current flowing through each resistor in the circuit can be calculated by dividing the total voltage applied by the total resistance of the circuit.In your case, you have already determined that the total current flowing through the circuit is 0.5A and the total resistance of the circuit is 10 ohms. Using these values, you can calculate the current flowing through each resistor in the circuit by dividing the total voltage applied by the resistance of each individual resistor.For example, if the circuit contains two resistors with resistances of 5 ohms and 3 ohms, respectively, the current flowing through each resistor would be 0.5A * (5 ohms / 10 ohms) = 0.25A for the 5 ohm resistor and 0.5A * (3 ohms / 10 ohms) = 0.15A for the 3 ohm resistor.In general, the current flowing through each resistor in a combo circuit can be calculated by dividing the total current flowing through the circuit by the number of resistors in the circuit, and then dividing the result by the resistance of each individual resistor. This will give you the current flowing through each resistor in the circuit.To learn more about Combo Circuit refer to:

A friend of yours bought several dozen pure silver rings on a recent trip abroad, but now suspects
that they might not be all that pure. He brings them to you to check. You weigh 10 of the rings and
find that each ring has a mass of 0.738g, you then place them in a graduated cylinder 2.5cm in
diameter and observe that the water level rises by 8.45mm. S.G of pure silver = 10.49
Using chemical engineering concepts, determine if the rings are pure silver.
Answer:
3
Explanation:
To determine if the rings are pure silver, we can calculate the density of the rings and compare it to the density of pure silver. The density of a material is the mass of the material per unit volume.
First, we need to find the volume of one of the rings. Since the rings are cylindrical, we can use the formula for the volume of a cylinder to find the volume of each ring:
V = π * r^2 * h
Where V is the volume of the ring, π is approximately equal to 3.14, r is the radius of the ring, and h is the height of the ring. In this case, the height of the ring is equal to the thickness of the ring, which is equal to the change in the water level (8.45 mm) divided by the number of rings (10). The radius of the ring is equal to half the diameter of the graduated cylinder (2.5 cm / 2 = 1.25 cm), since the rings are placed in the cylinder side by side.
Plugging these values into the formula, we find that the volume of each ring is:
V = 3.14 * (1.25 cm)^2 * (8.45 mm / 10) = 0.00367 cm^3
Next, we can use the mass and volume of each ring to calculate the density of the rings:
density = mass / volume
Since the mass of each ring is 0.738g and the volume of each ring is 0.00367 cm^3, the density of the rings is:
density = 0.738 g / 0.00367 cm^3 = 201.09 g/cm^3
Finally, we can compare the density of the rings to the density of pure silver, which is 10.49 g/cm^3. Since the density of the rings is much higher than the density of pure silver, it is likely that the rings are not pure silver.
It is important to note that this calculation is only an approximate estimation of the purity of the rings. There may be other factors that affect the density of the rings, such as impurities or variations in the thickness of the rings. Additionally, the value of the density of pure silver used in this calculation may not be entirely accurate, as the density of a material can vary depending on factors such as temperature and pressure. A more precise determination of the purity of the rings would require further testing and analysis.
in class you learned that when streamlines curve there is a pressure gradient: the pressure is always higher on the outside of the curve. why is that so
The pressure is always higher on the outside of the curve because this side will push the flow and make a curve.
What is streamlines curve?Streamlines curve is a streamline that have shape like curve. Streamlines curve can created because there is a pressure gradient in different level, if the pressure gradient doesn't have different level it will continue streamline and create straight line not a curve.
The higher level of pressure gradient that make streamline curve will push the flow into one side and create the opposite of curve direction which is been called as outside of the curve. Because of this, wherever the higher level of pressure is located it will push the flow and make curve and that position will be outside of the curve.

A country needs to build new power plants to meet
the increasing demand for electric power. One possibility is
to build coal-fired power plants, which cost $1300 per kW
to construct and have an efficiency of 40 percent. Another
possibility is to build clean-burning Integrated Gasification
Combined Cycle (IGCC) plants where the coal is subjected to
heat and pressure to gasify it while removing sulfur and particulate matter from it. The gaseous coal is then burned in a
gas turbine, and part of the waste heat from the exhaust gases
is recovered to generate steam for the steam turbine. The construction of IGCC plants costs about $1500 per kW, but their
efficiency is about 48 percent. The average heating value of
the coal is about 28,000,000 kJ per ton (that is, 28,000,000 kJ
of heat is released when 1 ton of coal is burned). If the IGCC
plant is to recover its cost difference from fuel savings in five
years, determine what the price of coal should be in $ per ton.
Answer:
To determine the price of coal that would allow the IGCC plant to recover its cost difference from fuel savings in five years, we first need to calculate the cost savings of the IGCC plant compared to the coal-fired power plant. The IGCC plant costs $1500 per kW to construct and has an efficiency of 48 percent, while the coal-fired power plant costs $1300 per kW to construct and has an efficiency of 40 percent. The cost savings of the IGCC plant can be calculated as follows:
$1500/kW - $1300/kW = $200/kW
We can then calculate the total cost savings of the IGCC plant over a five-year period by multiplying the cost savings per kW by the total number of kW the plant will generate in five years. For this calculation, we will assume that the plant will generate 1,000 kW of power.
$200/kW * 1000 kW = $200000
Next, we need to calculate the amount of coal that the IGCC plant would need to burn over a five-year period to generate 1,000 kW of power. We know that the average heating value of coal is 28,000,000 kJ per ton, and that the efficiency of the IGCC plant is 48 percent. We can calculate the amount of coal the IGCC plant would need to burn as follows:
1,000 kW / (28,000,000 kJ/ton * 0.48) = 10.7 tons
Finally, we can calculate the price of coal that would allow the IGCC plant to recover its cost difference from fuel savings in five years by dividing the total cost savings by the amount of coal the plant would need to burn over the same period.
$200000 / 10.7 tons = $18,661.04/ton
Therefore, the price of coal that would allow the IGCC plant to recover its cost difference from fuel savings in five years is $18,661.04/ton.

Add the rated voltage to the size of the breaker. A 20 amp breaker, for instance, will have a maximum load of 2400 watts while running at 120 volts (20 amps x 120 volts). Lighting loads for residential units are often not regarded as continuous loads for calculation purposes. Some loads in home wiring would need to be computed at 125 percent of the entire load and should be treated as continuous loads. You must determine the load weight if it has not been specified; otherwise, it has not been supplied. Use the following formula to calculate the volume of the load and the materials that make it up: load weight = weight per volume * total volume.

A ball is thrown upward with an initial velocity of 20m/s
.a) How long is the ball in the air?
b) What is the greatest height reached by the ball?
c) When is the ball 15m above the ground?
Ball is 2.04 sec in the air after it will undergoes free fall, Max height 20.14 m and after 0.99 sec the ball 15m above the ground.
What are the equations of motion?First Equation of Motion : v = u + a t.Second Equation of Motion : s = u t + 1/2 a t ²Third Equation of Motion : v ²= u² + 2 a s.The most basic principles of an object's motion are described by kinematics equations of motion. These equations control an object's motion in 1D, 2D, and 3D. They make it simple to compute expressions like an object's position, velocity, or acceleration at different points in time.
At max height, V=0.
So:
v=u+at
0=20–9.8t
9.8t=20
t=2.04 secs…
Ball is 2.04 sec in the air after it will undergoes free fall.
s = ut + ½ at^2
=20* 2.04 - (9.8 * 2.04² / 2)
= 40.8 - 20.39
= 20.41 m
Max height 20.14 m
ball 15m above the ground:
v^2 = u^2 + 2 as.
= 20^2 - 2 * 9.8 * 15
= 400- 294
=106
v = [tex]\sqrt{106}[/tex] =10.3 m/s
v=u+at
10.3 = 20 -9.8 * t
t = (20 -10.3) /9.8 = 0.99 sec
at 0.99 sec the ball 15m above the ground.
