Answer:
A substance that produces a lot of heat on burning is called;
Fuel
Explanation:
A fuel can be described as a material that can release energy such as heat energy or work when it is reacted with other material for example the reaction involving fuel substances such as, gas, wood, oil, or coal, and oxygen during burning (combustion) that produces heat energy, power and light.
A quantity of gas has a pressure of 1.39 atm and a volume of 6.95 L. What is the
volume of this gas when the pressure is changed to 740 mm Hg?
Answer:
The volume of the quantity of gas when the pressure changes to 740 mm Hg is approximately 9.92 L
Explanation:
The properties of the quantity of gas are;
The initial pressure of the gas, P₁ = 1.39 atm
The initial volume of the given volume of gas, V₁ = 6.95 L
The final pressure of the quantity of gas, P₂ = 740 mmHg
Boyle's Law states that at constant temperature, the pressure, P, of a given mass of gas is inversely proportional to its volume, V
Mathematically Boyle's Law can be written as follows;
[tex]P \propto \dfrac{1}{V}[/tex]
Therefore, we have;
P₁·V₁ = P₂·V₂
Where;
V₂ = The final volume of the quantity of gas when the pressure changes to 740 mm Hg
[tex]\therefore V_2 = \dfrac{P_1 \cdot V_1}{P_2}[/tex]
By substituting the known values, we have;
[tex]V_2 = \dfrac{1.39 \ atm \times 6.95 \ L}{740 \ mmHg} = \dfrac{1.39 \ atm \times 6.95 \ L}{0.973521 \ atm} = 9.92159459459 \ L \approx 9.92 \ L[/tex]
The final volume of the quantity of gas when the pressure changes to 740 mm Hg = V₂ ≈ 9.92 L
According to the
simple machine below, which part of the system is
considered the resistance force? *
2 points
A
B
Answer:
The part of the system that is considered the resistance force is;
B
Explanation:
The simple machine is a system of pulley that has two pulleys
The effort, which is the input force at A gives the value of the tension at C and D which are used to lift the load B
Therefore, we have;
A = C = D
B = C + D = C + C = 2·C
∴ C = B/2
We have;
C = B/2 = A
Therefore, with the pulley only a force, A equivalent to half the weight, B, of the load is required to lift the load, B
The resistance force is the constant force in the system that that requires an input force to overcome in order for work to be done
It is the force acting to oppose the sum of the other forces system, such as a force acting in opposition to an input force
Therefore, the resistance force is the load force, B, for which the input force, A, is required in order for the load to be lifted.

Find the mechanical average of a wheel axle System of the wheel has a radius of 1.5 feet in the accident has a radius of 6 inches if the force is put on a axle
Answer:
Mechanical average of a wheel = 3
Explanation:
Given:
Radius of wheel = 1.5 ft = 1.5 x 12 = 18 inches
Radius of axle = 6 inches
Find:
Mechanical average of a wheel
Computation:
Mechanical average of a wheel = Radius of wheel / Radius of axle
Mechanical average of a wheel = 18 / 6
Mechanical average of a wheel = 3

When engineers develop a model, which step in the engineering process is
taking place
Answer: Design a solution or problem
Explanation:
When engineers develop a model, the step that is taking place in the engineering process is referred to as the design a solution or problem step.
This is when engineers tackles and solved a problem by finding solutions and this is done by incorporating their analytical, and synthetic thinking and using their skills an experience.
Engineering models are used create a simulation intended to solve real world problems. Hence, the process of developing a model describes designing a solution.
To solve a particular problem in the real world, the use of engineering modeling softwares or programs which are embedded with mathematical and environmental parameters are utilized to create a design of the phenomenon in other to prepare a simulated process to test the effectiveness of their work before deployment.
Therefore, developing a model describes the process of designing a solution.

Which explanation best identifies why the company in the following scenario has decided against investing in solar energy?
A company in Miami, Florida, is considering an alternative energy source in order to cut down on its fuel costs. The company has thought about solar energy but has decided against it for the time being.
The company found the negative environmental effects of solar energy disheartening.
The company found the amount of sunlight in the area unreliable.
The company found the cost of the required photovoltaic cells too expensive.
The company found the natural resources used in solar energy too limited.
Answer:
The company found the cost of the required photovoltaic cells too expensive.
Explanation:
Solar energy can be used as an alternative source of supply for fuel. Solar energy is a renewable source of energy, that is it keeps on replenishing every day. Also solar energy does not require a lot of maintenance.
The cost required is starting a solar system is very high because one needs to buy solar panel, photovoltaic cells for batteries, inverters and so on.
From the question, the company decided against solar energy for the time being. This means that probably in the future they might consider it. Therefore it is as a result of the economic situation of the company that they have not set up a solar system because the cost of the required photovoltaic cells too expensive.

6. What is the Density of a block that has a mass of 82lbs in a block with a
volume of 6in^3*
1 point
13.6lbs/in^3
O 36/bs/in
8lbs/in^3
O 13.6lbs/in"2
Answer:
[tex]d=13.6\ lbs/in^3[/tex]
Explanation:
Given that,
Mass of a block, m = 82 lbs
Volume of the block, V = 6 inch³
We need to find the density of the block. Density of an object is equal to the mass per unit its volume. So,
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{82\ lbs}{6\ in^3}\\\\=13.6\ lbs/in^3[/tex]
So, the required density is [tex]13.6\ lbs/in^3[/tex].
