Protons and neutrons are held together inside the nucleus.
Explanation:
The strongest force in the universe is the nuclear forces holding the neuclons together in an atom.
This force is referred to as the strong nuclear forces. It is by far stronger than electromagnetic forces.
Nuclear forces are stronger than chemical binding forces which is seen between two particles attracting one another via static electricity.
It stronger than the gravitational force experienced by two equal masses that falls to the ground at the same speed.

Answer:
(A)
Explanation:
about 1.4 times the mass of our sun.
Question:
In a manufacturing process, a large, cylindrical roller is used to flatten material fed beneath it. The diameter of the roller is 6.00 m, and, while being driven into rotation around a fixed axis, its angular position is expressed as θ = 2.70t² − 0.900t3³
where θ is in radians and t is in seconds.
(a) Find the maximum angular speed of the roller.
(b) What is the maximum tangential speed of a point on the rim of the roller?
(c) At what time t should the driving force be removed from the roller so that the roller does not reverse its direction of rotation?
(d) Through how many rotations has the roller turned between t = 0 and the time found in part (c)?
Answer:
a. 2.7rad/s
b. 8.1 m/s
c. 2 s
d. 3.6 rad
Explanation:
Let:
Vx = the pulling component of force
Vy = the lifting component of force
Vy:
Sin(n°) = Vy/hypotenuse
hypotenuse * Sin(n°) = Vy
100N*sin(30°) = Vy
50N = Vy
Vx:
Cos(n°) = Vx/hypotenuse
Hypotenuse * cos(n°) = Vx
100N*cos(30°) =Vx
about 86.6N = Vx
Answer:
4.5 m/s
Explanation:
ignore the mass, it doesn't matter
speed is defined as distance/time
both are given so just divide the two
