The change in momentum for the system containing both blocks will be 250 kg m/s.
<h3>How to calculate the momentum?</h3>
The momentum of an object simply means the product of the mass and the speed of the object.
In this case, the change in momentum will be:
P = (2 + 3)50
P = 5 × 50
P = 250 kg m/s
In conclusion, the change in momentum is 250 kg m/s.

<em>The concentration, mobility, and valence state of the ionized species in a solution, as well as the temperature at which the measurement is done, all have a role. The conductivity of water increases with the concentration of ions in it.</em>
Based on the calculations, a good approximation for x when f(x) = 30 is equal to: B. 20.
<h3>How to write the equation?</h3>
Based on complete information, the equation for the line of best fit for the set of values in the table is given by this function below:
f(x) ≈ 1.8x - 5.4
Thus, a good approximation for x when f(x) = 30 would be determine by substituting the value of f(x) with 30 as follows:
30 = 1.8x - 5.4
30 + 5.4 = 1.8x
35.4 = 1.8x
x = 35.4/1.8
x = 20.
