Answer:
C. a small charged particle.
Explanation:
typically beta radiation emits an electron which is a small negativity charged particle.
hope it helps. :)
Answer:
So do 2400 divided by 70. I got 34.285714 and the numbers behind the decimal are repeating. If you round it you get 34.3
<h2>Basic Research - Option B</h2>
Experimenting to determine the fundamental properties of x-rays would be an example of basic research. The experimental primary analysis tries to determine the laws of the events. The primary analysis is expected to know the stuff, its sort, its characteristics and its performance. It examines to get the speculation. To obtain wherewith the stuff performance yet not how to practice these forms for a firm determination.
The research of the characteristics of the particle to explain whatever it is, how it combines with other atoms, how it determines the characteristics of the material are some instances of primary analysis. For example examining to ascertain the basic features of x-rays. Spencer's research on WWII radar technology that drove to the discovery of the microwave furnace.
Edison's research and application of other scientists task is to create the light bulb, and Morrison and Franscioni's research was made to build the Frisbee models of applied research science.
Answer:
the short version is density
Explanation:
so the outer part of the nebula is cold and dark 10-20k but at this temutre the gas clumps together heating it up more mass = more gravity = more heat and the gravity will pull more mass that will give the proto star the spherical shape we all know and love
Here we have a circular motion. In that type of motion two new forces appear: centrifugal and centripetal. Centrifugal force tries to move object away frome the center of rotation. Centripetal force is the reason why object moves in a circle.
According to Newton's first law, in order for water not to spill out total force acting on water must be equal to zero. Forces acting on the water are gravitational and centrifugal.

Forces have opposite signs as they act in opposite directions. But their value is the same so we can ignore signs:
