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.

Explanation:
4 ft – 6 ½ in. to inches. Record your answer in fractional inches.
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
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.

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

.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.

What function does large volumes of moving water have in generating electricity
Answer:
Hydropower is a method of generating electricity that uses moving water (kinetic energy) to produce electricity. In large-scale hydropower plants the moving water drives large water turbines, and dams are needed to store water in lakes, reservoirs and rivers for later release.

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
