Answer:
A is the correct option.
Explanation:
Physics primer is a set of mathematics topics that are relevant to introductory physics courses. The idea behind the physics primer is to provide the students a strong base of mathematics concept that can be helpful for them in the future courses of physics. It should be taken before the introductory lessons of physics. It will help out students in solving those physics problems that involves mathematics. Physics primer is usually comprised of tutorials, answers of specific questions and videos.
Answer:
Explanation:
Some data in the problem are missing.
Missing values:
Radius of the cylinder: 13 cm
Height of the cylinder: 4 cm
The volume of a cylinder is given by
where
r is the radius of the base of the cylinder
h is the height of the cylinder
In this problem, we have:
r = 13 cm (radius)
h = 4 cm (height)
Therefore, the volume of the cylinder is:
Answer: it is C
The thermistor
Explanation:
Thermistors (temperature-sensitive, or thermal, resistors) are used as temperature-measuring devices and in electrical circuits to compensate for temperature variations of other components. They are also used to measure radio-frequency power and radiant power, such as infrared and visible light.
To measure the intensity of the electromagnetic wave after knowing the frequency, we can calculate it by using fast fourier transformations (FFT).
