The answer to this question is letter "D" or the last item in the choices which is the nuclear fusion "It occurs with very small atoms with low mass".
The first statement, the second, as well as the third statement, is not true because these three statements are referring to nuclear fission.
Answer:
<h3>The answer is 122.5 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume = 7 mL
density = 17.5 g/mL
We have
mass = 17.5 × 7
We have the final answer as
<h3>122.5 g</h3>

The mass of this much chain is 0.22 grams for 7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car.
<h3>What are weight and mass?</h3>
Mass is the amount of the substance and object and the weight is the gravitational force required to act upon the particular mass of the substance.
To calculate the mass of car divide the wight to the gravity value 9.8 meter per second.
mass = weight / gravity
substituting the value,
mass = 2.16 / 9.8
mass = 0.22 grams
Therefore,7.5m of Grade 70 tow chain, which has a diameter of /38" and weighs 2.16/kgm, to tow a car the mass will be 0.22 grams.
