Answer:
7.8 Mph
Explanation:
Rate of cycling = 1.1 rev/s
Rear wheel diameter = 26 inches
Diameter of sprocket on pedal = 6 inches
Diameter of sprocket on rear wheel = 4 inches
Circumference of rear wheel = \pi d=26\piπd=26π
Speed would be
\begin{gathered}\text{Rate of cycling}\times \frac{\text{Diameter of sprocket on pedal}}{\text{Diameter of sprocket on rear wheel}}\times{\text{Circumference of rear wheel}}\\ =1.1\times \frac{6}{4}\times 26\pi\\ =134.77432\ inches/s\end{gathered}Rate of cycling×Diameter of sprocket on rear wheelDiameter of sprocket on pedal×Circumference of rear wheel=1.1×46×26π=134.77432 inches/s
Converting to mph
1\ inch/s=\frac{1}{63360}\times 3600\ mph1 inch/s=633601×3600 mph
134.77432\ inches/s=134.77432\times \frac{1}{63360}\times 3600\ mph=7.65763\ mph134.77432 inches/s=134.77432×633601×3600 mph=7.65763 mph

i have two numbers that sum to 16 and have a difference of 3. by forming two equations and solving them, find the two numbers
Answer:
(x=9.5 and y=6.5) or ( x=6.5 and y = 9.5)
Explanation:
Let equations be
x+y = 16
If
x-y = 3
Now, Adding both equations, we get
x+y+x-y = 16+3
2x = 19
x=19/2 = 9.5
y = 16-9.5 = 6.5
Now y-x = 3
Now, Adding both equations, we get
x+y+y-x = 16+3
2y = 19
y=19/2 = 9.5
x = 16-9.5 = 6.5

Daniel Wiseman, a scientist for Gres-Trans Corp., wants to determine if the flow rate of a particular material changes with different changes in temperature. The data is plotted in the figure below. What type of relationship exists between the flow rate and the change in temperature? negative curved positive there is no relationship
Answer: C. There is no relationship
Explanation:
At the various temperatures, the flow rates do not seem to show any relation as similar temperatures can yield different flow rates.
The flow rates neither appear to generally increase nor decrease as a result of a decrease or an increase in temperature which means that there is a lack of a positive, negative and curvilinear relationship.
There is simply no relationship.

in a circuit 3resistor are connected in parallel R¹=10ohms R²=15ohms R³=30ohms 1. calculate total resistance 2. total current flow 3.voltge drop across each resistor 4.total dissipated by the circuit 5. power in the 15ohms
I'll give you the formula to calculate the net resistance of multiple resistors I'm in parallel.
1/R = 1/R1 + 1/R2 +1/R3 +……+1/Rn.
Take the reciprocal of each resistor value and add them up. The reciprocal value of a resistor is called its admittance. Add them up to get the total admittance. Notice that this value is 1/R. So take the reciprocal by dividing 1 by the total admittance value. Then you have the net resistance for all the parallel resistors.
Now you know the total resistance of the parallel values, if there are any other resistors in series with this, add them on to get the total resistance in the circuit.
Now use Ohm's law to find the current.
I =V/R
1. paralel resistance
1/(1/10+1/15+1/30)= 30/6=5 Ohms
2. total current : V/R=24/5= 4.8A

.Match the benefit of full synthetic oil with engine conditions: If oil is thicker, engines lose power and efficiency.
A) Synthetic improves engine protection by resisting oil breakdown.
B) Synthetic has greater resistance to oil thickening to maintain engine efficiency.
C) Synthetic provides maximum protection in extreme hot and cold temperature conditions
Synthetic has greater resistance to oil thickening to maintain engine efficiency. The correct option is B.
What is engine efficiency?An engine's efficiency is defined as the ratio of useful work done to heat provided is the completed work Please keep in mind that the term "work done" refers to the power delivered at the clutch or driveshaft.
This means that the work done by thermodynamic expansion is reduced by friction and other losses.
Lower viscosity without sacrificing wear protection and better cold-flow, both of which improve fuel economy, are possible with synthetic oil.
Thus, the correct option is B.
