Counting gives an exact number and exact numbers have infinite sig figs.
If I remember correctly, it would be B. A very large amount of energy is produced from a tremendous mass.
Answer:
C. Y & Z
Explanation:
V, W are imaginary metals here because their valence electrons are typically less than 4. X, Y, Z are non-metals and have higher valence electrons. Here, if V or W bind with X, Y, or Z we make ionic bond (because metal + non metal = ionic). But, if X binds with Y or Z or any combinations of any two of the three non-metals results in covalent bond (non metal + non metal = covalent).
Thus, Y and Z make covalent.
Answer:
<h2>The answer is 4 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
where
a is the acceleration
f is the force
m is the mass
From the question
f = 20 N
m = 5 kg
We have
We have the final answer as
<h3>4 m/s²</h3>
