Explanation:
The nucleus of an atom is dense because it contains more of particles in a very little space.
The nucleus is the center of an atom made up of the protons and neutrons.
Atomic nucleus is very small compared to the size of the atom.
Density is function of mass and volume.
Mass is the amount of matter in a substance.
Volume is the space occupied by a substance.
The more the mass the more the density.
Since protons and neutron are massive bodies occupying a small space, they make the nucleus very dense.

Answer:
250 m
Explanation:
The car in this problem is moving of uniform accelerated motion, so we can use the following suvat equation:
where
s is the distance covered
u is the initial velocity
t is the time
a is the acceleration
Assuming the car starts from rest,
u = 0
Also we know that
a = 5 m/s^2 (acceleration of the car)
t = 10 s
Substituting, we find the distance covered:
Answer:
1.8 m/s
Explanation:
here's the solution : -
momentum = mass × velocity
=》18 × 0.1
=》1.8 m/s
Because solo gold isn't strong material. But with admixture it's stronger.
