which of the following is a nonmetallic mineral resource that is used as a building material?

False. A power gain of 3 dB is not equivalent to an output power that is twice the power of the input.

In decibels (dB), a power gain of 3 dB represents a multiplication factor of approximately 1.414. To calculate the actual power ratio, we convert the dB value back to a linear scaleThe formula to convert dB to a linear scale is: linear scale value = 10^(dB/10).For a power gain of 3 dB, the calculation would be: linear scale value = 10^(3/10) = 1.414.This means that the output power is approximately 1.414 times (or √2 times) the power of the input, not twice. Therefore, the statement that a power gain of 3 dB is equivalent to an output power that is twice the power of the input is false.

The mass moment of inertia, also known as the rotational inertia, is a measure of an object's resistance to changes in its rotational motion. It depends on the object's mass distribution and the axis of rotation. In the case of a rod of mass m and length L about a transverse axis located at its end, we can determine its mass moment of inertia.

To calculate the mass moment of inertia of the rod, we need to consider the rotational inertia contributed by each infinitesimally small element of mass dm in the rod. Let's consider a small element of length dx at a distance x from the end of the rod. The mass of this small element is dm = (m/L)dx, as the mass is distributed uniformly along the rod.

The mass moment of inertia of this small element about the transverse axis at the end is given by dI = dm * x^2. Substituting dm = (m/L)dx, we have dI = (m/L) * x^2 * dx.

To find the total mass moment of inertia of the entire rod, we integrate this expression over the entire length of the rod (from x = 0 to x = L). Thus, the mass moment of inertia I is given by:

I = ∫(0 to L) (m/L) * x^2 * dx.

Evaluating this integral, we get:

I = (m/L) * [x^3/3] from x = 0 to x = L.

Simplifying further:

I = (m/L) * [(L^3)/3 - 0^3/3].

I = (m/L) * (L^3)/3.

I = (1/3) * mL^2.

Therefore, the correct answer is (b) (1/3) mL^2, which represents the mass moment of inertia of a rod of mass m and length L about a transverse axis located at its end.

The power formula is why high-power electrical loads are designed for higher voltages whenever possible.

The power formula is given by:

Power (P) = Voltage (V) × Current (I)

According to the power formula, power is directly proportional to voltage. Therefore, for a given power requirement, increasing the voltage allows for a decrease in the current needed to deliver that power. This relationship is described by Ohm's law, which states that current is inversely proportional to voltage for a fixed resistance.

When high-power electrical loads, such as motors, appliances, or industrial equipment, are designed for higher voltages, it allows for lower current levels to achieve the same power output. Lower currents result in reduced resistive losses, which can lead to improved efficiency and lower heat generation in the electrical system.

By utilizing higher voltages, electrical systems can transmit power more efficiently over long distances, as higher voltages experience less voltage drop and lower transmission losses. Additionally, higher voltages can allow for the use of smaller conductors and components, reducing material and installation costs.

However, it's important to note that working with higher voltages requires appropriate safety precautions and adherence to electrical codes and regulations. Proper insulation, grounding, and protective devices should be implemented to ensure the safe operation of high-voltage electrical systems.

The pneumatic (reed) type stall warning system installed in some light aircraft is activated by "A- static air pressure."

In this type of stall warning system, static air pressure is used to trigger the activation of the warning mechanism. The system typically consists of a small opening on the leading edge of the aircraft's wing or other aerodynamic surfaces. This opening is connected to a tube that leads to the cockpit where the warning device is located.

During normal flight conditions, the static air pressure entering the opening is relatively steady. However, when the angle of attack of the aircraft increases and reaches a critical point, the airflow over the wing becomes disrupted, causing a decrease in static air pressure at the opening. This drop in pressure is sensed by a reed or a similar mechanism within the warning system.

The decrease in static air pressure causes the reed to vibrate or oscillate, creating an audible warning sound or activating a visual indicator in the cockpit. This serves as an alert to the pilot that the aircraft is approaching a stall condition, indicating the need to take corrective action to prevent an aerodynamic stall.

By utilizing static air pressure as the triggering mechanism, the pneumatic (reed) type stall warning system provides a simple and reliable means of alerting pilots to potential stall conditions during flight.

The net tension in the bolts can be determined by considering the forces acting on the pipe. By summing the weight of the pipe and the pressure forces, we can determine the net tension in the bolts.

To determine the net tension in the bolts of the pipe shown in Fig. P8.87, we need to consider the forces acting on the pipe. Since minor losses are neglected and the wheels are assumed to be frictionless, the only significant forces to consider are the weight of the pipe and the pressure forces exerted by the water. The weight of the pipe acts downward and can be calculated by multiplying the mass of the pipe by the acceleration due to gravity. The pressure forces exerted by the water inside the pipe act in both upward and downward directions. The net tension in the bolts is the difference between these upward and downward pressure forces.

To calculate the upward pressure force, we need to determine the pressure at the bottom of the pipe and multiply it by the cross-sectional area of the pipe. The downward pressure force can be obtained by multiplying the pressure at the top of the pipe by the cross-sectional area. The net tension is then the difference between these two pressure forces.

Where: E = modulus of elasticity F = axial force (8000 lb in this case) L = length of bar (5 in.) A = cross-sectional area (0.8 in2) ΔL = change in length (0.002 in.) Plugging in the given values, we get: E = (8000 lb * 5 in.) / (0.8 in2 * 0.002 in.) E = 25,000,000 lb/in2 Therefore, the modulus of elasticity of the material is 25,000,000 lb/in2. This means that the material is quite stiff and can withstand large amounts of stress before it begins to deform.
