Answer:

Statement 1: All balls hit the ground at the same time

Explanation:

When there is no resistance of air, the acceleration due to gravity experienced by all the bodies are same. So for falling bodies, neglecting the air resistance, the falling object will be weightless and therefore all the objects will hit the ground at the same time when there is nor air resistance and the objects are considered to be falling in vacuum.

The average cost of each trip is $8 per trip while the marginal cost is $0

We are given;

Monthly payment by Frank for Membership fees = $80

Number of times frank goes to the center monthly = 10 times

Thus, average cost is;

Average cost = Monthly payment/Number of visits in a month

Average Cost = $80/10

Average Cost = $8 per trip

The marginal cost is the change in total production cost that comes from making or producing one additional unit. However, in this question, his monthly pay covers an unlimited use of its facilities. Thus, there can be no marginal cost for an additional work-out session. Thus;

Marginal Cost = $0

The statement made in the Question or problem above is TRUE/correct. The term known as " catch basin" is an important and essential part of the drainage system that is should be built in a community(whether housing community, industrial community or commercial community).

The catch basin is very important because it helps in making sure that they act as sieve to get all the dirt such as leaves from water running on the surface(runoffs).

Answer:

10 cents/kwh

Explanation:

Base monthly charge = $10.00

First 100 kwh at $0.16/kwh = $16.00

Next 200 kwh at $0.10/kwh = $20.00

Remaining 400 kwh at $0.06/kwh = $24.00

Total charge = $10 + $16 + $20 + $24 /(100+200+400)

Average cost = $70/700 or 10 cents/kwh

Sarah is on a see saw with her friend. The pivot or fixed point where the bar is free to move is called the  Fulcrum. Hence, option C is correct.

The support or base that a lever rotates on in order to lift or move anything. The verb fulcire, which means "to prop," is the root of the Latin term fulcrum, which means "bedpost."

The term "fulcrum" was first used in the 17th century to describe the pivotal point of a lever or other similar mechanism, such as the oar of a boat.

The Fulcrum line of road bike wheels offers lightweight and durable wheelsets for every circumstance, course, discipline, and price range. From the top-tier full carbon aero wheels to the high performance aluminum line, Fulcrum offers the perfect wheel to match your performance.

Thus, option C is correct.

Answer:

[tex]250\ \text{lbm/min}[/tex]

[tex]625\ \text{ft/min}[/tex]

Explanation:

[tex]A_1[/tex] = Area of section 1 = [tex]10\ \text{ft}^2[/tex]

[tex]V_1[/tex] = Velocity of water at section 1 = 100 ft/min

[tex]v_1[/tex] = Specific volume at section 1 = [tex]4\ \text{ft}^3/\text{lbm}[/tex]

[tex]\rho[/tex] = Density of fluid = [tex]0.2\ \text{lb/ft}^3[/tex]

[tex]A_2[/tex] = Area of section 2 = [tex]2\ \text{ft}^2[/tex]

Mass flow rate is given by

[tex]m=\rho A_1V_1=\dfrac{A_1V_1}{v_1}\\\Rightarrow m=\dfrac{10\times 100}{4}\\\Rightarrow m=250\ \text{lbm/min}[/tex]

The mass flow rate through the pipe is [tex]250\ \text{lbm/min}[/tex]

As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1

[tex]m=\rho A_2V_2\\\Rightarrow V_2=\dfrac{m}{\rho A_2}\\\Rightarrow V_2=\dfrac{250}{0.2\times 2}\\\Rightarrow V_2=625\ \text{ft/min}[/tex]

The speed at section 2 is [tex]625\ \text{ft/min}[/tex].

(a) The mass flow rate will be "250 lbm/min".

(b) At section 2, the speed will be "625 ft/min".

According to the question,

Section 1 area, A₁ = 10 ft²

Section 2 area, A₂ = 2 ft²

Water's velocity, V₁ = 100 ft/min

Volume at section 1, v₁ = 4 ft³/lbm

(a) We know the formula,

Mass flow rate, m = ρA₁V₁

                              = [tex]\frac{A_1 V_1}{v_1}[/tex]

By substituting the values,

                              = [tex]\frac{10\times 100}{4}[/tex]

                              = [tex]\frac{1000}{4}[/tex]

                              = 250 lbm/min

(2) The speed will be:

→ m = ρA₂V₂

or,

  V₂ = [tex]\frac{m}{\rho A_2}[/tex]

By substituting the values,

       = [tex]\frac{250}{0.2\times 2}[/tex]

       = [tex]\frac{200}{0.4}[/tex]

       = 625 ft/min

Answer: Nuclear to thermal to mechanical to electrical.

Explanation:

Nuclear energy is also referred to as atomic energy which will then lead to the generation of the thermal energy. It should be noted that the thermal energy is also referred to as the heat energy and this is due to the rise in temperature which results in the faster movement of atoms and their collision with one another.

This in turn, brings about the mechanical energy which is simply the energy caused by the motion and this in turn, also lead to electrical energy.

Therefore, the correct answer is Nuclear to thermal to mechanical to electrical.

When testing for available voltage to the load, you should always place the negative meter lead on the ground and the positive meter leads at various points in the circuit where voltage is expected. The correct option is B.

Voltage is a power source that is given to the tube. It pushes the charged electrons to the conducting loop. It is an electrical potential difference.

Set the positive meter leads in various locations throughout the circuit where voltage is anticipated, and the negative meter leads on the ground.

Thus, the correct option is B.

Answer:

2.0%

Explanation:

Percentage of aggregate = 94%

Specific gravity = 2.65

Specific gravity of asphalt = 1.9

Density of mix = 147pcf = 147lb/ft³

Total weight of mix: (volume = 1ft³)

= (147lb/ft³)(1ft³)

= 147lb

Percentage weight of asphalt in mix:

100% - 94%

= 6%

Weight of asphalt binders

= 6% x 147lb

= 8.82lb

Weight of aggregate in mix:

= 94% x 147

= 138.18lb

Specific weight of asphalt binder:

(Gab)(Yw)

Yw = specific Weight of water

= 62.4lb

Gab = specific gravity of asphalt binder

= 1.0

(62.4lb)(1.0)

= 62.4 lb/ft³

Volume of asphalt in binder:

8.82/62.4

= 0.14ft³

Specific weight of binder in mix:

2.65 x 62.4lb/ft³

= 165.36 lb/ft³

Volume of aggregate:

= 138.18/165.36

= 0.84ft³

Volume of void in the mix:

1ft³ - 0.84ft³ - 0.14ft³

= 0.02ft³

The percentage of void in total mix:

VTM = (0.02ft³/1ft³)100

= 2.0%

Tech A says that a CAT III meter is required when working on the EV or HEV high-voltage system. Tech B says that a HEV can start the ICE on its own if the "Ready" indicator is on. Both are correct.

There's a lot of confusion out there about the requirements for working on high-voltage systems in hybrid and electric vehicles. Tech A says that a CAT III meter is required, while Tech B says that a HEV can start the ICE on its own if the "Ready" indicator is on. So who's right?

Both techs are actually correct. A CAT III meter is required when working on the EV or HEV high-voltage system. However, a HEV can start the ICE on its own if the "Ready" indicator is on.

The bottom line is that you need to be very careful when working on high-voltage systems. Make sure you have the proper equipment and training before attempting any repairs.

The probability that the wavelengths of the next photosynthetically active radiations is at most 82 nanometer is 0.35.

Photosynthetically active radiation (PAR) is light with wavelengths ranging from 400 to 700 nm that is used by plants for photosynthesis.

The photon flux density of photosynthetic photon flux density (PPFD) is defined as the photon flux density of PAR.

Photosynthesis and plant growth require Photosynthetically Active Radiation. Higher PAR promotes plant growth, and monitoring PAR is critical to ensure plants receive enough light for this process.

Given that,

a = 75

b =95

Using uniform distribution

P(x c) = (c - a) / (b - a)

P(x 82) = (82 - 75) / (95 - 75)=0.35

Probability=0.35

Thus, the probability of the given scenario is 0.35.

A percentage increase from 80 to 100 is equal to 25%.

A percentage can be defined as any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.

In Mathematics, there are two main types of percentage and these include the following:

Mathematically, percentage increase can be calculated by using this formula:

Percentage increase = [Final value - Initial value]/Initial value × 100

Substituting the given parameters into the formula, we have;

Percentage increase = [100 - 80]/80 × 100

Percentage increase = [20]/80 × 100

Percentage increase = 1/4 × 100

Percentage increase = 25%.
