Answer:
Isotope of carbon-12.
Explanation:
The MOLE is a unit of measurement of the amount of a pure substance which contains exactly the same number of chemical units which could be (Atoms, molecules etc.) posses atoms in exactly 
grams of isotope of carbon-12 (i.e., 
).
So, The mole is the Notation used for an amount as same the 12 number is used for dozen for making count of Bananas and many more.
The is known as the fundamental constant names Avogadro's number (
), It is in the honor of Italian scientist Amedeo Avogadro.
Answer:
<h3>The answer is 8.91 m/s²</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>8.91 m/s²</h3>
Hope this helps you
Answer:
The ball travels a distance of 20 m in the time interval of 4 s
Explanation:
Using s = ut + 1/2at² where s = distance travelled by the ball, u = initial velocity of ball = 0 m/s (since it starts from rest), a = acceleration of the ball = 2.50 m/s² and t = time = 4 s.
Substituting the variables into the equation, we have
s = ut + 1/2at²
s = 0 × 4 s + 1/2 × 2.50 m/s² × (4 s)²
s = 0 + 1/2 × 2.50 m/s² × 16 s²
s = 1/2 × 40 m
s = 20 m
So, the ball travels a distance of 20 m in the time interval of 4 s.
Given Information:
Charge = q = 7.0x10⁻⁶ C
Required Information:
Number of electrons = n = ?
Answer:
Number of electrons = 4.375x10¹³
Explanation:
We know that charge is given by
q = n*e
Where n is the number of electrons and e is the electronic charge that is 1.60x10⁻¹⁹ C
n = q/e
n = 7.0x10⁻⁶/1.60x10⁻¹⁹
n = 4.375x10¹³ electrons
Therefore, 4.375x10¹³ electrons were transferred.
