Explanation:
The nucleus of an atom can be modeled as several protons and neutrons closely packed together.
Mass of the particle,
Radius of the particle,
(a) The density of the nucleus of an atom is given by mass per unit area of the particle. Mathematically, it is given by :
, V is the volume of the particle
So, the density of the nucleus of an atom is .
(b) Density of iron,
Taking ratio of the density of nucleus of an atom and the density of iron as :
So, the density of the nucleus of an atom is times greater than the density of iron. Hence, this is the required solution.
Answer:
The horizontal distance traveled by the rocket is 90.46 m
Explanation:
Given;
initial velocity of the rocket, u = 30 m/s
angle of projection, θ = 40°
the horizontal distance traveled by the rocket = ?
The horizontal distance traveled by the rocket is given by the range of the projectile.
The range of the projectile is given as;
Therefore, the horizontal distance traveled by the rocket is 90.46 m
The closest answer in the given options is 90.54 m
