Answer:
unknow e and f
Explanation:
In experiments with alpha particles that are obtained by the method of radioactive decay of atoms, some parameters are known
a) Known. The initial velocity is given by the energy of the particles entities by the atomic nuclei
b) Known. The particle charge always 2e, helium core
c) Known. It is set in the given experiment, in general it is selected as zero
d) Known. Placed by the experimenter
e) Unknown. The speed depends on the interactions with the system
f) Unknown. It depends on the interactions with the system, because the position depends on the interactions
g) Known. It is always the value of a helium nucleo
Answer:
Both forces act along the line joining the objects like masses or charges. And both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law.
Explanation:
Well it depends on what kind of liquid, some liquids if you heat it up itll turn into a solid, but most just turn into a gas
Answer:
There are 4 liquids in this experiment and red is the least dense of all of them so it should float on top, which it is doing.
The red that you see at the bottom is neither liquid nor is it a part of the experiment.
It is simply the <u>color of the bottom of the container</u> that the experiment was conducted in.
Please remember to post in the right category next time :)
.40 as a fraction is 4/10 or 2/5
the 4 is in the tenths place, so put it over a 10 to make it a fraction.
then, simplify the fraction by dividing the numerator and denominator by 2, and you get 2/5
