<h2>1.67 m/s²</h2>
Explanation:
The car’s acceleration can be found by using the formula
![a = \frac{v - u}{t} \\](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7Bv%20-%20u%7D%7Bt%7D%20%20%5C%5C%20)
where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have
![a = \frac{25 - 15}{6} = \frac{10}{6} = \frac{5}{3} \\ = 1.666666...](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B25%20-%2015%7D%7B6%7D%20%20%3D%20%20%5Cfrac%7B10%7D%7B6%7D%20%20%3D%20%20%5Cfrac%7B5%7D%7B3%7D%20%20%5C%5C%20%20%3D%201.666666...)
We have the final answer as
<h3>1.67 m/s²</h3>

Explanation:
If you're wondering what causes cancer, it is rapid and uncontrollable cell regeneration. The majority of cancers result from random mutations arising during DNA replication in the normal stem cells required during development and tissue maintenance.
Answer:
The initial and final states of the hydrogen atom were n=2 and n=6 respectively.
Explanation:
We must first obtain the energy of the photon;
E= hc/λ
where;
h= Plank's constant = 6.6 * 10^-34 JS
c= speed of light = 3* 10^8 m/s
λ = wavelength of light= 411 nm = 411* 10^-9 m
Substituting values;
E = 6.6 * 10^-34 * 3* 10^8 / 411* 10^-9
E = 4.8 * 10^-19 J or 3.0 eV
But ;
En = 13.6/n^2
So E = En final - En initial
3.0 = -13.6(1/n^2final - 1/n^2initial)
If we substitute n^2final = 6 and n^2 initial = 2 then the RHS becomes approximately equal to the LHS
Therefore the initial and final states of the hydrogen atom were n=2 and n=6 respectively.
