B.
silica
C.
concrete
D.
cement
Answer:
A
Explanation:
It is also a toxic material
Answer:
The correct answer is A. Lead.
Explanation:
I got it right on the Plato test.
Tech A says an atom with more electrons than protons has an overall positive charge.
Tech B says not all atoms can give up or accept electrons easily. Who is correct?
Tech B is correct because his statement accurately reflects the diverse nature of atoms regarding their electron transfer capabilities.
Can all atoms easily give up or accept electrons?Tech B is correct in stating that not all atoms can easily give up or accept electrons. The ability of an atom to gain or lose electrons depends on its atomic structure and the distribution of its electrons in the outermost energy level, known as the valence shell.
Atoms strive to achieve a stable electron configuration typically by obtaining a full valence shell with eight electrons (the octet rule), which is more stable. The elements with fewer than four or more than four valence electrons are typically more reactive as they either tend to gain or lose electrons to achieve a stable configuration.

A ductile hot rolled steel bar has a minimum yield strength in tension and compression of 350 MPa. Using the distortion energy and maximum shear stress theories . Determine the factor of safety for following plane stress states.
(a) Factor of safety: Fs = 350 / 28.87 = 12.11. (b) Factor of safety: Fs = 350 / 23.84 = 14.68. (c) Factor of safety: Fs = 350 / 49.56 = 7.06. (d) Allowable stress: σallow = min(τmax / 0.577, σmax / 1.732) = min(53.76 / 0.577, 88
The factor of safety against yielding is given by the ratio of the yield strength to the maximum allowable stress. For plane stress, the maximum allowable stress is determined by the distortion energy and maximum shear stress theories. Using these theories, we can calculate the maximum allowable stress for each plane stress state and then calculate the factor of safety.
(a) For σₓ = σy = 100 MPa,
Maximum shear stress theory: τmax = σ/2 = 100/2 = 50 MPa
Distortion energy theory: σmax = (σₓ + σy)/2 + √[(σₓ - σy)/2]^2 + τxy^2 = 100 + √0 + 0 = 100 MPa
Allowable stress: σallow = min(τmax / 0.577, σmax / 1.732) = min(50 / 0.577, 100 / 1.732) = 28.87 MPa
Factor of safety: Fs = 350 / 28.87 = 12.11
(b) For σₓ = 100 MPa and σy = 50 MPa,
Maximum shear stress theory: τmax = (σₓ - σy)/2 = 25 MPa
Distortion energy theory: σmax = (σₓ + σy)/2 + √[(σₓ - σy)/2]^2 + τxy^2 = 75 + √562.5 = 88.96 MPa
Allowable stress: σallow = min(τmax / 0.577, σmax / 1.732) = min(25 / 0.577, 88.96 / 1.732) = 23.84 MPa
Factor of safety: Fs = 350 / 23.84 = 14.68
(c) For σₓ = 100 MPa and Tₓy = -75 MPa,
Maximum shear stress theory: τmax = (σₓ + |Tₓy|)/2 = 87.5 MPa
Distortion energy theory: σmax = (σₓ + σy)/2 + √[(σₓ - σy)/2]^2 + τxy^2 = 100 + √(1875 + 5625) = 182.32 MPa
Allowable stress: σallow = min(τmax / 0.577, σmax / 1.732) = min(87.5 / 0.577, 182.32 / 1.732) = 49.56 MPa
Factor of safety: Fs = 350 / 49.56 = 7.06
(d) For σₓ = -50 MPa, σy = -75 MPa, and Txy = -50 MPa,
Maximum shear stress theory: τmax = √[(σₓ - σy)/2]^2 + Txy^2 = √[(25/2)^2 + 50^2] = 53.76 MPa
Distortion energy theory: σmax = √[(σₓ - σy)/2]^2 + Txy^2 + √[(σₓ + σy)/2]^2 = √[(25/2)^2 + 50^2] + √(625 + 5625)/2 = 88.96 MPa

1: A baseball is hit 4 feet above the ground leaves the bat with an initial speed of 98 ft/sec at an angle of 0 45 is caught by an outfielder at a height of 3 feet.
Answer:
299.36 feet
Explanation:
\(To \ find \ the \ distance \ of \ the \ ball \ from \ the \ home \ plate. \\ \\ From \ the \ given \ information:\)
\(Height \ h = 4 \ ft\)
\(Initial \ speed \ V_o = 98 \ ft/s ec\)
\(The \ angle \ \theta = 45^0\)
\(Acceleration \ due \ to \ gravity (g)= 32.2 \ ft/s\)
\(U_x = V_o \ cos 45 = \dfrac{98}{\sqrt{2}}\)
\(U_y = V_o \ sin 45 = \dfrac{98}{\sqrt{2}}\)
So;
\(S_y = u_y t - \dfrac{1}{2}gt^2\)
\(-1 =\dfrac{98}{\sqrt{2}}t - \dfrac{1}{2}*32*1.85t^2\)
By solving:
\(t_1 = 4.32 \ sec\)
Thus;
\(horizontal \ distance = U_x t\)
\(= \dfrac{98}{\sqrt{2}}\times 4.32\)
\(\mathbf{=299.36 \ feet}\)
\(\mathbf{Thus \ , the \ distance \ from \ the \ home \ plate \ = \ 299.36 \ feet}\)
When an aircraft is in a non-accelerated level flight, what are the relationships between lift, weight,thrust and drag?A) Lift is equal to weight and thrust exceeds drag.B) Lift is equal to weight and thrust is equal to drag.C) Lift is greater than weight and thrust is equal to drag.D) Lift is greater than weight and thrust exceeds drag.
When an aircraft is in a non-accelerated level flight, it means that the aircraft is flying at a constant speed without any changes in direction or altitude. In this situation, there are four main forces acting on the aircraft, which are lift, weight, thrust, and drag. option B is correct
Lift is the upward force generated by the wings, and it must be equal to the weight of the aircraft to maintain level flight. This is because the aircraft needs to overcome the force of gravity in order to stay in the air. Therefore, option B) "Lift is equal to weight and thrust is equal to drag" is correct.Thrust is the forward force generated by the engines, and it must be equal to the drag of the aircraft to maintain a constant speed. This is because the aircraft is moving through the air, and there is resistance created by the air molecules. The engines need to overcome this resistance to maintain a constant speed. Option A) "Lift is equal to weight and thrust exceeds drag" is incorrect because if the thrust exceeds drag, the aircraft would be accelerating and not in a non-accelerated level flight. Option C) "Lift is greater than weight and thrust is equal to drag" is also incorrect because if the lift is greater than weight, the aircraft would be climbing and not in a non-accelerated level flight. Option D) "Lift is greater than weight and thrust exceeds drag" is incorrect for the same reason as option A), if the thrust exceeds drag, the aircraft would be accelerating and not in a non-accelerated level flight. In conclusion, when an aircraft is in a non-accelerated level flight, the relationships between lift, weight, thrust, and drag are that lift is equal to weight and thrust is equal to drag.For such more question on altitude

Timeline
For a project like this that is relatively simple, the timeline depends on how large your team is. With 10 people working on a garden shed, it could be finished in a matter of hours, but doing it alone may take 2-3 weekends of time.
A risk register is a log of all potential hazards, risks, and uncertainties that a project may encounter. It also has an explanation of the probability of the danger occurring and its potential impact.
A risk register's purpose is to assist in the identification, assessment, and management of risks associated with a project and is an essential part of a successful risk management strategy. As such, the risk register has six components, including the risk description, risk cause, impact, risk likelihood, risk impact, and risk ranking.The following are six potential hazards for Project A and their explanations:
1. Weather Issues: Bad weather can slow down the construction process, make it dangerous to work outside, or damage materials.
2. Availability of Materials: If materials are scarce, it can delay or halt the construction project.
3. Time Constraints: Limited time can result in project delays or cutting corners, which can impact the quality of work.
4. Cost Overruns: Unexpected or uncontrollable costs can result in the project being halted or completed poorly.
5. Inadequate or Faulty Tools: This can affect work quality, safety, and efficiency, ultimately impacting the project schedule and costs.
6. Safety Issues: Inadequate safety protocols can result in accidents that could lead to injury or death of workers on the site.In conclusion, the risk register for Project A should outline potential hazards, their causes, impact, likelihood, and ranking, as well as mitigation strategies. The risk register should be reviewed and updated regularly to ensure that new risks are identified and addressed.

Based on structural considerations only, the thickness of the slab in a standard-module one-way joist floor need not exceed 3 inches.
In a standard-module one-way joist floor system, the primary load-carrying members are the joists, which span between supports such as beams or walls. The slab acts as a non-structural element, primarily providing a smooth and level surface for the floor.
The thickness of the slab is determined based on factors such as fire rating requirements, deflection limits, and finishing requirements. However, from a structural standpoint, a slab thickness of 3 inches is typically sufficient to support the intended loads and provide the necessary strength and rigidity.

g The pump inlet is located 1 m above an arbitrary datum. The pressure and velocity at the inlet are 100 kPa and 2 m/s, respectively. The pump exit is located 4 m above the same datum. The pressure and velocity are 500 kPa and 3 m/s, respectively. How much power is required to drive this pump assuming and efficiency of 75%
Answer:
The power needed to drive this pump assuming and efficiency of 75% is 1874.0 watts (W)
Explanation:
Solution:
Given that:
Velocity = 2 m/s
Pressure = 100 kPa
The pump exit is =4 m
Efficiency 75%
Thus,
We apply the method called the Bernoulli's equation between two reservoirs
p₁ / ps + v₁²/2g + z₁
=p₂/ps/v₂²/2g +z₂ + hL
The density of gasoline (pg) is = 680 kg m³
The gravity of acceleration is known to be =9.81 m/s²
So,
100/680 *9.81 + 2²/2 *9.81 + 1 = 500/ 680 * 9.81 + 3²/2 * 9.81 +4 + hL
16. 2 = 79.41 + hL
hl =79.41 - 16.2
hL =63.21 m
the unit weight of gasoline is(γ) = 680 * 9.81 = 6670.8 m/s
Now we find the efficiency
The efficiency (η) = The output power /Input power
Where hL =H
The input power = γ * Q * H/0.75
=6670.8 *12/3600 * 63.21
=6670.8 * 0.333 * 63.21
=6670.8 *0.2107
=1405.5/0.75
