Spent lead-acid batteries are exempt from hazardous waste regulations if they are recycled.
True
False

Answers

Answer 1

Answer:

If your spent lead-acid batteries will be reclaimed through regeneration, you are exempt from all of the hazardous waste regulations except for Part 261 and §262.11 (both of which are waste identification requirements). ... The Universal Waste rules in Part 273 apply to all types of batteries that would be hazardous waste

Explanation:

Answer 2

Spent lead-acid batteries are exempted from hazardous waste regulations if they are recycled: A. True.

What is recycling?

Recycling refers to a waste management technique that typically involves the process of converting a product that has reached the end of its life cyle into new and reusable products (items).

According to the Environmental Protection Agency (EPA), all spent lead-acid batteries are exempted from hazardous waste regulations only if they are recycled.

Answer:

  see attached for a diagram and loads

Explanation:

The mass of the man represents a downward force of ...

  F = ma

  F = (85 kg)(9.8 m/s²) = 833 N

at a point 1.5 meters from one support. In the attached diagram, the man is standing left of center, so is 1.5 m from the left support, and 4.9 m from the right support.

The mass of the beam represents a downward force of ...

  F = (15 kg)(9.8 m/s²) = 147 N

This is effectively modeled by a force acting on the center of the beam, 3.2 m from each support. The distance between supports is 6.8 -2(0.2) = 6.4 m.

The net torque on the beam is zero. This means we can sum the torques at either support and set them to zero. If we let s1 represent the upward force supplied by the left pillar, and s2 the upward force supplied by the right pillar, the two torque equations are ...

  torque = force × distance

  CW torque about the left pillar: 833×1.5 +147×3.2 -s2×6.4 = 0

     s2 = 1719.9/6.4 ≈ 268.7 . . . newtons

  CCW torque about the right pillar: -s1×6.4 +833×4.9 +147×3.2 = 0

     s1 = 4552.1/6.4 ≈ 711.3 . . . newtons

The magnitudes of the loads carried by the supports are 268.7 N and 711.3 N.

__

Check

For static equilibrium, the sum of upward forces must match the sum of downward forces:

  268.7 +711.3 = 980 . . . . newtons (total of upward forces)

  883 +147 = 980 . . . . . . . newtons (total of downward forces)

What does the line strung between the batter boards represent?

Answers

Batter boards (or battre boards, Sometimes mispronounced as "battle boads") are temporary frames, set beyond the corners of a planned foundation at precise elevations. These batter boards are then used to hold layout lines (construction twine) to indicate the limits (edges and corners) of the foundation.

Batter boards are temporary boards set up so string lines can be attached between them. These lines represent the final height, length and depth of the slab. Drive some stakes into the ground next to the batter boards you just placed on the ground.

Liquid water flows isothermally at 20°C through a one-inlet, one-exit duct operating at steady state. The duct’s inlet and exit diameters are 0.02 m and 0.1 m, respectively. At the inlet, the velocity is 10 m/s and pressure is 1 bar. At the exit, determine the mass flow rate, in kg/s, and velocity, in m/s.

Answers

The continuity equation allows finding the results for the speed and flow of the outlet pipe are:

 Q = 3.14 kg / s  v₂ = 0.4 m / s

Fluid mechanics studies the movement and fluid dynamics, it is described  by two fundamental relationships:

The Bernoulli equation that an expression of the energy conservation  

          [tex]P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2[/tex]  

Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.

The continuity equation which is an expression that our principle of mass conservation for fluids

            [tex]A_1v_1 = A_2 v_2[/tex]

Where A₁ and A₂ is the area of ​​the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet

They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity

         [tex]v_2 = ( \frac{A_1}{A_2} )^2 \ v_1[/tex]  

the cross section of the tavern is

        A = [tex]\pi r^2 = \pi \ d^2/4[/tex]  

Where r is the radius and d is the diameter

Let's substitutes

         

        [tex]v_2 = (\frac{d_1}{d_2} )^2 \ v_1[/tex]  

        [tex]v_2 = (\frac{0.02}{0.1} )^2 \ 10[/tex]  

        v₂ = 0.4 m / s

The flow  (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore

        Q = A v

        Q = [tex]\pi \frac{d_2^2}{4} \ v_2[/tex]π d2 ^ 2 v2

        Q = [tex]\pi \ \frac{0.1^2}{4} \ 0.4[/tex]

        Q = 3.14 10⁻³ m ^ 3 / s

As the transported liquid is water

         1 liter water = 1 kg

Consequently

         1 m³ = 1000 liter = 1000 kg of water

Let's reduce the flow

         Q = 3.14 10⁻³ m³/s ( [tex]\frac{10^3 kg}{1 m^3}[/tex] )

         Q = 3.14 kg / s

In conclusion using the continuity equation we can find the results for the speed and flow of the outlet pipe are:

 v₂ = 0.4 m / s  Q = 3.14 kg / s

On-site oil storage containers must be marked “Used Oil.”
True
False

Answers

Answer:true

Explanation:g

On-site oil storage containers must be marked “Used Oil.” is the true statement.

What kind of container can be store oil in?

Steel containers have long been used to hold oils and other liquids, but regular steel is known to rust, corrode, and degrade more quickly than stronger materials. A stainless steel container offers more protection, and storing oil in one won't result in rust problems.

Use of glass or metal containers is their greatest option. If a person plan to store something in the refrigerator, use containers that can handle the cold. No matter what kind of oil you have, you must keep it away from light. Always keep them out of the way, covered, and away from direct light. The oil should be kept in a cool, dark location, like your pantry. Keep it away from the light and the stove. The oil will oxidize more quickly in the presence of heat and light.

Thus, it is a true statement.

two technicians are describing how an air-conditioning system gets rid of the heat. Technician A says that heat always flows from the hotter to the colder object. Technician B says that as refrigerant evaporates, it absorbs heat as it changes from a liquid to a gas. which technician is correct?

Answers

Based on the information provided by these technicians, both of them are correct.

How does heat flow?

According to heating, ventilation, and air conditioning (HVAC), heat in an air-conditioning system generally flows from the hotter object to the colder object.

As the refrigerant evaporates in a small radiator-type unit (evaporator), it absorbs heat as it changes phase from liquid to gas. Also, as the heat is being absorbed by the refrigerant, the small radiator-type unit (evaporator) becomes cold.

In conclusion, we can logically deduce that both of them are correct.

Explanation:

a burglar's car had a start with an acceleration of 2m/s . A police vigilant party cane after 5seconds and continued to chase the burglar's car with a uniform velocity of 20m/s . find the time taken in which the police van will overtake the burglar's car​

Answers

Explanation:

Let the distance covered after which the police party catches the burglar is ‘s ’.

Let ‘t ’ be the time and given that the police came after 5sec, therefore the time taken by police to catch the burglar is ‘t−5 ’.

The burglar’s car will start moving from rest, therefore initial velocity is, u=0

Given that the acceleration is 2m/s

Applying the equation of motion,

S1=ut+12at2

⇒S1=0×t+12×2×t2

⇒S1=0×t+12×2×t2

⇒S1=t2 -----------(i)

Since the police’s car is moving at uniform velocity, therefore acceleration will be =0, Also u=20m/s.

Again applying the equation of motion to the police car,

⇒S2=ut+12at2

On substituting the corresponding values, we get

⇒S2=20(t−5)+12×0×t2

⇒S2=20t−100 -------(ii)

Since the time at which the police car catches the burglar’s car is to be calculated, therefore

S1=S2

⇒t2=2t−100

⇒t2−20t+100=0

we can rewrite the above equation as,

⇒(t−10)2=0

⇒(t−10)(t−10)=0

On solving,

⇒t=10

The time taken by the police is t−5=10−5=5sec.
