The answer to your question is "Yes". Great numbers of people ... chemists,
physicists, and common folks alike ... know what Uranium is.
=================================
Uranium is one of the 92 elements that are found to occur in nature.
In the Periodic Table of the Elements, it is Element #92 ... Its atoms
contain 92 protons in their nucleii.
Answer:
11.87 ms⁻¹
Explanation:
You can use the kinematic equation
v² = u² + 2as
Where v = final velocity
u = initial velocity
a = acceleration
s = displacement
v² = 9² + 2×1.5×20
So you get v = 11.87 ms⁻¹
Answer:
The distance is 
Explanation:
From the question we are told that
The wavelength is 
The distance of the screen is x = 4.80 m
The location of the fourth order bright fringe is y = 8.20 cm = 0.082 m
The order of the fringe is n = 4
Generally the position of a fringe with respect to the central fringe is mathematically represented as

Where d is the distance between the slits, so making d the subject

substituting values


A chemical change because it doesn't power anything or secrete anything except smoke.
