Answer:
The mnemonic I can use to memorize the metric prefixes in this order is: Gigantic Monsters Killed One Million Men Napping Peacefully. All right, so again, gigantic monsters killed one million men napping peacefully.
-- 'Ca' (Calcium) is an element.
-- The proton has a positive charge.
-- Nuclear fusion results in the synthesis of atoms of new elements.
-- H₂O (water) is a chemical compound.
-- Nuclear fission is a decay of the nucleus.
-- The atomic number of an element is the number of protons
in each atom of it.
-- I suppose you're using the Greek letter <span>η ('eta', not 'nu')
to represent the neutron.
-- I suppose you're using ' e ' to represent the electron.

B.strong but weaker than the weak force
<u>Answer
</u>
He should make the arrow for “Path” curve downward.
<u>Explanation
</u>
The force of gravity is usually directly downward. So from the diagram, it is correctly labelled.
If the object was given a horizontal force, the direction of the inertial is also correct. Inertial is the force the resist the change of state of motion.
What Hector should change is the path followed by the object. It will be a curve not a straight line as it is drawn.
The correct answer is He should make the arrow for “Path” curve downward.
Answer:
a=-4.2 m/s²
Explanation:
The horse riding so inital velocity is given finally the rider stops so the final velocity is zero.
initial velocity =Vi= 21 m/s
final velocity =Vf= 0 m/s
distance covered = S=52 m
By using 2nd equation of motion we can find the acceleration
2aS=Vf² -Vi²
a=(-441)/104
a=-4.2 m/s²
So the accceleration is 4.2 m/s².
