The answer is Solid.
Have a great day m8!
Answer:
a) distance is 4+7+1+8=20 blocks
b) displacement is 10 blocks
Explanation:
find displacement: x and y
x axis displacement = 4-1 = 3 blocks
y axis displacement = -7+8= 1 block
displacement = the square root of 3^2 + 1^2
= 9+1 = 10 blocks.
You can find the angle of displacement with respect to the initial position using trig identities, if you wish.

As there was no electric charge on neutrons, and they did not get affected by electromagnetic fields.
Explanation:
The functions of the neutron in atoms is:
To hold the nuclei with coulombic repulsion between the protons.
The neutron has no charge on it and hence were not discovered.
Its mass is slightly less than the proton.
It provides stability to the atom.
Lord Chadwick is credited to prove the existence and discovery of neutron.
He proved that the nucleus of the atom has its mass in the centre as neutron+ proton.
He bombarded beryllium with alpha particles, and found high energy radiation.
