Explanation:
Acceleration of an object is calculated by finding the change in its velocity divided by time taken.
If 
is initial velocity, 
is final velocity and t is time taken. Then the acceleration of the object is given by :
.....(1)
So, the above equation is used to find acceleration. It is called the first equation of motion. After rearranging equation (1), the correct options are :
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.

Answer:
λ = 2.62 x 10⁻¹⁰ m = 0.262 nm
Explanation:
We can use Bragg's Law's equation to solve this problem. The Bragg's Law's equation is written as follows:
mλ = 2d Sin θ
where,
m = order of reflection = 1
λ = wavelength = ?
d = distance between the planes of crystal = 3.5 x 10⁻¹⁰ m
θ = strike angle of waves on plane = 22°
Therefore, substituting the respective values in the equation, we get:
(1)λ = (2)(3.5 x 10⁻¹⁰ m)(Sin 22°)
<u>λ = 2.62 x 10⁻¹⁰ m = 0.262 nm</u>
