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.
Conduction is what you're looking for. The two substances are in contact, so heat flows from the warmer to the cooler until they equalize.
Answer:
196J or 200J
Explanation:
Potential Energy = mgh
m( mass) = 10gm
h ( height) = 2m
g = 9.8 or 10 m/s ^2 ( choose whichever one is taught to you, usually in my school its 9.8 if the value isn't given )
PE = 10 × 10 × 2 = 200 J
or
PE = 10 × 9.8 × 2 = 196 J
Hope it helps
Answer:
The particle comes to rest before reaching the position x=4m.
Explanation:
When the object is at x=0m, all of its energy is kinetic energy. Using the equation for kinetic energy yields KE=1/2mv^2=(12)(2)(3)^2=9J. Using the given equation for potential energy when the object is at x=4m yields U=4x^2=4(4)^2=64J. Since the system only has 9J of energy, the object comes to rest before reaching x=4m.
