Answer:
52 m/s
Explanation:
Wavelength is the distance between two successive crests. Two crests make one circle hence 16 cycles are equal to 16 wavelengths. Each wavelength is equal to 208/16=13 m long
Speed of wave is given as the product of wavelength and frequency, expressed as
S=fw
Where f is the frequency and w is the wavelength
Substituting 13 m for w and 4 Hz for f then
S=4*13=52 m/s
Therefore, the speed is equivalent to 52 m/s
Answer: Experimenting to determine the fundamental properties of x-rays.
Explanation:
Scientific basic research aims to find the fundaments or principles of the phenomena.
The basic research is intended to understand the matter, its nature, its properties, its behavior. It searches to make theory. To finding how the things work but not how to use those things for a determined purpose.
The study of the properties of the atom to understand what it is, how it interacts with other atoms, how it determines the properties of the matter are some examples of basic research, such as experimenting to determine the fundamental properties of x-rays is.
On the other hand, the other examples given, Spencer's research on WWII radar technology that led to the invention of the microwave oven, Edison's research and use of other scientists' work to invent the light bulb, and Morrison and Franscioni's research done to create the Frisbee, are examples of applied research science. This is research to find a valuable use of some scientific knowledge.
Answer:
An asteroid is a minor planet of the inner Solar System. Historically, these terms have been applied to any astronomical object orbiting the Sun.
Answer:
Physics can help you in your everyday life.
Explanation:
It can also help you in life treating situations.
When its temperature increases, the reactants have more kinetic energy so the frequency of effective collision increases, resulting in a faster rate of chemical reaction.
