The types of radiation are Alpha, Beta and gamma radiation
Alpha radiation: is a radiation of particles like He elements. It is very heavy radiation. it can be stopped by a sheet of a paper.
Beta radiation: is a radiation of particles like as the electrons, with the same mass and positive or negative charge. It can be stopped by an aluminium sheet
Gamma radiation: is an electromagnetic radiation with out really mass, moves in the speed of the light and has very high energy, high frequency and very short wavelengths. It can be stopped only by a block of concrete, lead, or other heavy shielding.
Thus, the radiation has the lowest penetrating ability is <u>Alpha radiation (particles)</u>
Answer:
Yeah it's the new trend lol it's kinda weird
Answer:
Option D. 4.4 m/s²
Explanation:
The following data were obtained from the question:
Velocity (v) = 21 m/s
Radius (r) = 100 m
Centripetal acceleration (a) =.?
The centripetal acceleration of the car can be obtained as follow:
Centripetal acceleration (a) = Velocity square (v²) / radius (r)
a = v²/r
a = 21²/100
a = 441/100
a = 4.41 ≈ 4.4 m/s²
Therefore, the centripetal acceleration of the car is 4.4 m/s².
<span>All of these are directly proportional to each other, meaning that if one goes up or down, they all do the same.
So if the temperature increases so does the heat. If the heat increases then so does the thermal energy. If the temperature goes up then so does the thermal energy. ETC...</span>
Answer:
usually x-ray tube filaments are devices that limit the current flow i.e. current cannot easily pass through them or we can say that they are current limited devices. So to allow fine electron transmission control by filament heating current, rhenium must not be used in x-ray tube filaments.
