Answer: Because it is has a strong connection
Explanation:
Answer:
40.5% is abundance of X-122
Explanation:
we know there are two naturally occurring isotopes of X, X-120 and X-122.
First of all we will set the fraction for both isotopes
X for the isotopes having mass 122
1-x for isotopes having mass 12
0
The average atomic mass of X is 120.81 amu
we will use the following equation,
122x + 120 (1-x) = 120.81
122x + 120 - 120x = 120.81
122x- 120x = 120.81 -120
2x = 0.81
x= 0.81/2
x= 0.405
0.405 × 100 = 40.5%
40.5% is abundance of X-122 because we solve the fraction x.
now we will calculate the abundance of X-120.
(1-x)
1 - 0.405 = 0.595
0.595 × 100 = 59.5 %
59.5 % for X-120.

Answer:</h3>
- She needs to know how long it took for her mom to get to her destination.
- She needs to know how far her mom drove.
<h3>
Explanation:</h3>
- Velocity is a vector quantity, which means it has both magnitude and direction.
- It is the ratio of displacement to time taken.
That is; Velocity = Displacement ÷ Time taken
In our case;
Malika needs to determine the velocity of her mom's car.
- Apart from knowing the direction the car travels, she also needs to know the time it takes her mom to reach her destination and how far her mom drove.
- Therefore, if it took her mom time, t seconds to drove for a distance, d meters. Then her mom's car velocity would be;
Velocity, v = d/t m/s
