Answer:

Past tense of hear = heard

Correct option is d.estimate landing loading rate.The anteroposterior ground reaction force could be used to estimate landing loading rate.

The anteroposterior ground reaction force is a measure of the force exerted by the body on the ground during movement. It represents the component of the force that acts in the forward-backward direction. By analyzing the anteroposterior ground reaction force, it is possible to estimate the landing loading rate, which refers to the rate at which force is applied to the body upon landing.

During activities such as jumping, the landing loading rate is an important parameter to consider as it can affect the risk of injury. A higher landing loading rate indicates a rapid increase in force upon landing, which may result in greater stress on the joints and tissues of the body.

Conversely, a lower landing loading rate suggests a more gradual increase in force, which can be less detrimental to the body.

By using the anteroposterior ground reaction force, researchers and practitioners can assess the landing loading rate and make informed decisions regarding training, rehabilitation, and injury prevention strategies.

Monitoring and analyzing this parameter can help identify individuals who may be at a higher risk of injury due to excessive loading rates and enable the implementation of targeted interventions to reduce injury risk.

Answer:

diameter of the sprue at the bottom is 1.603 cm

Explanation:

Given data;

Flow rate, Q = 400 cm³/s

cross section of sprue: Round

Diameter of sprue at the top \(d_{top}\) = 3.4 cm

Height of sprue, h = 20 cm = 0.2 m

acceleration due to gravity g = 9.81 m/s²

Calculate the velocity at the sprue base

\(V_{base}\) = √2gh

we substitute

\(V_{base}\) = √(2 × 9.81 m/s² × 0.2 m )

\(V_{base}\) = 1.98091 m/s

\(V_{base}\) = 198.091 cm/s

diameter of the sprue at the bottom will be;

Q = AV = (π\(d_{bottom}^2\)/4) × \(V_{base}\)

\(d_{bottom}\) = √(4Q/π\(V_{base}\))

we substitute our values into the equation;

\(d_{bottom}\) = √(4(400 cm³/s) / (π×198.091 cm/s))

\(d_{bottom}\)  = 1.603 cm

Therefore, diameter of the sprue at the bottom is 1.603 cm

Under NFPA 70E, the appropriate PPE for arc flash can be determined by conducting an arc flash hazard analysis which takes into consideration factors such as the incident energy level, working distance, and equipment ratings. This analysis helps to determine the appropriate level of protection needed for workers and ensures that they are equipped with the appropriate PPE, such as flame-resistant clothing, face shields, and gloves, to protect them from the potential hazards of arc flash.

The key factors considered in determining the appropriate PPE for arc flash include:

1. Incident Energy Analysis: This involves calculating the potential thermal energy released during an arc flash event at various locations within the electrical system. The incident energy is typically measured in calories per square centimeter (cal/cm²).

2. Arc Flash Boundary: The arc flash boundary is the distance from the arc source within which a worker could receive a second-degree burn (1.2 cal/cm²). It helps define the safe working distance and determines the level of PPE required for workers within that boundary.

3. PPE Categories: NFPA 70E defines PPE categories (ranging from 1 to 4) based on the incident energy level at a specific location. Each category specifies the minimum arc rating (expressed in cal/cm²) required for the PPE ensemble to protect against arc flash hazards.

By conducting the arc flash risk assessment and determining the incident energy levels at various locations within the electrical system, employers can identify the appropriate PPE category and select the corresponding PPE ensemble to provide adequate protection for workers against arc flash hazards. It is important to follow the guidelines and recommendations provided by NFPA 70E and consult with qualified electrical safety professionals to ensure compliance and worker safety.

Answer:

D) AND gate.

Explanation:

Given that:

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to la microprocessor acknowledging that it is ready to print

These conditions are:

1. The printer's electronic circuits must be energized.

2. Paper must be loaded and ready to advance.

3. The printer must be "on line" with the microprocessor.

Now; if these conditions are met  the logic gate produces a HIGH output indicating readiness to print.

The objective here is to determine the basic logic gate used in this circuit.

Now;

For NOR gate;

NOR gate gives HIGH only when all the inputs are low. but the question states it that "a HIGH is generated and applied to a 3-input logic gate". This already falsify NOR gate to be the right answer.

For NOT gate.

NOT gate operates with only one input and one output device but here; we are dealing with 3-input logic gate.

Similarly, OR gate gives output as a high if any one of the input signals is high but we need "a HIGH that is generated and applied to a 3-input logic gate".

Finally, AND gate output is HIGH only when all the input signal is HIGH and vice versa, i.e AND gate output is LOW only when all the input signal is LOW. So AND gate satisfies the given criteria that; all the three conditions must be true for the final signal to be HIGH.

Answer:

<E1, E2>.

Explanation:

So, in the question above we are given that the Two Electric field vectors E1 and E2 are perpendicular to each other. Thus, we are going to have the i and the j components for the two Electric Field that is E1 and E2 respectively. That is to say the addition we give us a resultant E which is an arbitrary vector;

E = |E| cos θi + |E| sin θj. -------------------(1).

Therefore, if we make use of the components division rule we will have something like what we have below;

x = |E2|/ |E| cos θ and y = |E1|/|E| sin θ

​

Therefore, we will now have;

E = x |E2| i + y |E1| j.

The base vectors is then Given as <E1, E2>.

a) The material is n-type. b. the electrical conductivity of the material is 8 x 10³ Siemens per meter (S/m).

a) The material is n-type because it has an excess of electrons due to the added Sb atoms, which act as donor impurities.

b) To calculate the electrical conductivity (σ), we can use the formula:

σ = q * (n * μn + p * μp)

Where:

q is the charge of an electron\((1.6 * 10^{-19} C)\)

n is the electron concentration (number of electrons per unit volume)

μn is the electron mobility (m²/V s)

p is the hole concentration (number of holes per unit volume)

μp is the hole mobility (m²/V s).

Given that virtually all the Sb atoms are ionized and contribute one charge carrier each, the electron concentration (n) is equal to the concentration of Sb atoms:\(n = 5 * 10^{22} Sb/m^3\)

Since the material is n-type, the hole concentration (p) can be considered negligible.

Plugging the values into the formula:

σ = \((1.6 * 10^{-19} C) * (5 * 10^{22} Sb/m^3) * (0.1 m^2/V s)\)

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.
