Answer: Option D, piezoelectric pressure guage
Explanation: Quartz crystal possess a very useful quality in science as they can generate small charges when pressure is applied to them or when they are hit. This property can be harnessed to construct a piezoelectric pressure gauge which would be used to measure and indicate changes in pressure, the quartz crystal releases little voltage each time there is an applied pressure . This device would be able to sense changes in pressure as there would voltage proportional to the applied pressure.
Answer:
The correct option is;
(a) High power density
Explanation:
The power density of a material is the amount of power per unit volume of the material. Power density, in the context of transformers, fuel cells, batteries, motors, and power supply units, is measured with respect to the volume, and the units is given as W/m³
A system such as a capacitor with an high power density has the capacity to put out large energy amount from a small volume. A capacitor with a high power density, can produce the same power output as a car battery and is said to have a high power density.
An effect might be a customer not wanting to buy it specifically because it’s by an airport, or maybe the customer wants to buy it because it’s right next to the airport, and a lot of people go to the airport so therefore they might go to the building next to the airport.
True
Explanation:
three point bending is better than tensile for evaluating the strength of ceramics. it is got a positive benefit to tensile for evaluating the strength of ceramics.

Plot a steam and leaf display for the given data
Start by categorizing the data by their tenth values:




The 0.3's is will be plotted as thus:

The 0.4's is as follows:

The 0.5's is as follows:

The 0.6's is as thus:

Lastly, the 0.7's is as thus:

The combined steam and leaf plot is:
