True
Variables is changing. It is any factor, trait or condition that can exist in differing amounts or types. An experiment has three types: Independent, Dependent and Controlled.
Answer:
Option C=> π+.
Explanation:
Just as it is given in the question above, we can see that the addition or combination of proton and neutron gives what is known as QUARKS.
Quarks are not easily measured because one can not see and study a quark independently; quarks move in multiples together.
The study of Quarks is very important in physics because they relate very well with electromagnetic force, strong force, weak force and Gravitational force.
"...When the remaining quarks combine to form a single particle, it is a π+".
π+ is a meson or a pion and it contains quarks and anti-quarks too
The volume of a cube is given by:
where L is the measure of each side (which corresponds to its width, since all sides of a cube are equal).
Plugging the data of the problem, L=32.1 cm, inside the equation, we find the volume:
Using the gravitational force of F= G(m1*m2/r^2)
m1= 5.97 x 10^24 kg (Earth)
m2= 1.99 x 10^30 kg (Sun)
r= 1.48 x 10^11 m
G is a known value, it is 6.672 x 10^-11
All units are proper. Therefore plug in the values and you get 3.16 x 10^22 N.
Let me know if I calculated this wrong and it is something else so I can delete this. Thank you. I don't want to make other students put down the wrong answer.
