Answer:
The SI base units are the standard units of measurement defined by the International System of Units (SI) for the seven base quantities of what is now known as the International System of Quantities: they are notably a basic set from which all other SI units can be derived.
Explanation:
Answer:
20 or 12
Explanation:
if it is 20 u will have to multiple 6 by 4 and the answer u will multiple it by2 and when it is 12 u will have to add 6 +4 and the answer u will add it to 2
The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of an atom. It is identical to the charge number of the nucleus. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons.
Answer:
B 23m/s
Explanation:
From the above information we get,
Initial velocity= 3m/s
Acceleration by gravity = 10 m/s2 (approx)
Time taken =2 seconds
v=u+at (First Equation Of Motion)
v= 3 + 10 × 2
v= 23 m/s
Answer:

Explanation:
The force is equal to the negative of the derivative of the potential energy function:

In this problem, the potential energy function is

Therefore, the force function is:

So, adding the units of measurement,
