Given that
4 ft – 6 ½ in.
To find,
We need to convert it it inches.
Solution,
We know that,
1 foot = 12 inches
4 feet = 4×12 inches
= 48 inches
[tex]4\ ft-6\dfrac{1}{2}\ in=48\ in+6\dfrac{1}{2}\ in\\\\=48+\dfrac{13}{2}\\\\=54.5\ \text{inches}\\\\=\dfrac{109}{2}\ \text{inches}[/tex]
Hence, 4 ft – 6 ½ in = 54.5 inches = 109/2 inches

How much thermal energy is needed to raise the temperature of 15kg gold from 45⁰ C up to 80⁰ C
Answer:
68.25 kJ
Explanation:
The thermal energy Q required to raise the temperature of 15kg gold from 45⁰ C up to 80⁰ C is Q = mcΔθ where m = mass of gold = 15 kg, c = specific heat capacity of gold = 130 J/kg°C and Δθ = temperature change = θ₂ - θ₁ where θ₁ = 45 °C and θ₂ = 80 °C
So, Q = mcΔθ = mc(θ₂ - θ₁)
= 15 kg × 130 J/kg°C × (80 °C - 45 °C)
= 1950 J/°C × 35 °C
= 68,250 J
= 68.25 kJ

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.

Technician A says when you ground a circuit, you hook it back to the positive side of the battery.
Answer:
Technician A should not only be fired but arrested for how incompetent and negligent he is.
Explanation:
Grounding a circuit is when you attach the ground wire to a clean metal surface that will disperse the excess electrical charges over a wide area so as not to create a shock.

A hand crank generator is used to power a light bulb. The person turning the crank uses 22 Newtons of input force to turn the crank 8 revolutions in 3 seconds. Each revolution of the crank equals 0.3 meters of distance that his hand moves. A multimeter connected to the light bulb records 0.08 amps of current and 9.04 volts.
1. Calculate the input power of the hand crank generator in Watts.
2. Calculate the output power of the hand crank generator in Watts.
3. Calculate the efficiency of the hand crank generator.
Answer:
1. The input power is 17.6 Watts
2. The output power is 0.7232 Watts
3.The efficiency of the hand crank generator is approximately 4.109%
Explanation:
The given parameters are;
The force with which the crank generator is turned = 22 Newtons
The rate at which the crank is turned = 8 revolutions per 3 seconds
The distance the hand moves during each revolution = 0.3 meters
The current recorded by the multimeter = 0.08 amps
The voltage recorded by the multimeter = 9.04 volts
1. Power = The rate of doing work = Work done/(Time taken to do the work) = Force × Distance/Time
∴ The power input of the hand crank generator = 22 × 0.3 × 8/3 = 17.6 Watts
2. The power output to the bulb, P, is given by the formula for electrical power as follows;
Power = Current, I × Voltage V
∴ P = 0.08 × 9.04 = 0.7232 Watts
3. Efficiency in percentage = Output/Input × 100
Therefore, the efficiency of the hand crank generator = )Output power/(Input power)) × 100 = (0.7232/17.6) × 100 ≈ 4.109%
Oliver is designing a new children’s slide to increase the speed at which a child can descend. His first design involved steel because it is a very strong material that can also be smooth. He found this was not a good option after all. Which explanation most logically explains why the steel was not optimal for this project?
A) Steel becomes too hot in the sun and can burn the children.
B) Steel is a composite material, and these rarely work well when building prototypes.
C) Steel is too malleable and therefore not sturdy enough.
D) Steel is an inorganic material, and these are rarely efficient.
Answer:
The correct option is;
A) Steel becomes too hot in the Sun and can burn the children
Explanation:
The properties of steel includes;
Low specific heat capacity, high thermal and electrical toughness, high hardness, high tensile strength, high yield strength, appreciable elongation, high fatigue strength, can easily corrode, high malleability and ability to creep
Therefore, due to the low specific heat capacity, which is 0.511 J/(g·°C) and high conductivity of steel which is about 32 W/(m·k), the temperature of the steel can rapidly rise and the hot steel surface can readily conduct the heat, (due to the temperature difference) to other bodies that come in contact
Answer:
Steel becomes too hot in the sun and can burn the children.

You get on your bike and pedal one rotation how far does the bike travel (if it stops right when the
pedal completes 1 rotation)? The diameter of the pedal sprocket is 2.5 inches. The diameter of the
wheel sprocket is 6 inches. The diameter of the back wheel is 24 inches.
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
The Speed of the bicycle is 7.8 mph
Technician A says that the gear ratios in the transmission give the vehicle an extended operating range.
Technician B says that the final drive assembly has various gear ratios that can be selected with a
gearshift lever. Who is correct?
Select one:
O a. Technician A
O b. Technician B
O c. Both A and B
O d. Neither A nor B
Based on the fact that Technician A says that the gear ratios in the transmission give the vehicle an extended operating range and Technician B says that the final drive assembly has various gear ratios that can be selected with a gearshift lever,
The person that is correct between the two of them is Technician A and this is because the gear ratios in the transmission shows how each gear which has a different diameter, and each of the axes rotates at a different speed when they are both engaged
What is a Gear Ratio?This refers to the ratio between the rotational speeds of two meshing gears.
Hence, we can see that Based on the fact that Technician A says that the gear ratios in the transmission give the vehicle an extended operating range and Technician B says that the final drive assembly has various gear ratios that can be selected with a gearshift lever,
The person that is correct between the two of them is Technician A and this is because the gear ratios in the transmission shows how each gear which has a different diameter, and each of the axes rotates at a different speed when they are both engaged
