Answer:
the awnser is a to determine motion of objects
Explanation:
The additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1
<h3>What is momentum?</h3>
Momentum can be defined as a scalar quantity that involves the multiplication of the mass of an object by its velocity.
In Physics, the momentum of an object such as a block, is calculated by using this formula;
Momentum = mass × velocity
In conclusion, we can deduce that the additional measurements which must be made to determine the momentum of block 2 after the collision is both the mass and the post-collision speed of block 1.

The options to fill in the gaps for the Long-run macroeconomic equilibrium are:
- equals
- intersects as a point on
<h3>What is macroeconomic equilibrium?</h3>
Macroeconomic equilibrium is an equilibrium situation that occurs when the quantities of the real GDP demanded equals the real GDP supplied at the point of intersection of the AD curve and the AS curve.
Long-run macroeconomic equilibrium occurs when aggregate demand equals short-run aggregate supply and they intersects as a point on the long-run supply curve.
In conclusion, Long-run macroeconomic equilibrium results in equilibrium of demand and supply of GDP.

The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.
<h3>What is the litters about?</h3>
Note that:
We take x = volume of 25% solution.
We take y = volume of 65% solution.
So, Equation of total volume:
x + y = 80
Hence the equation of amount of acid:
0.25x + 0.65y = 0.45(80)
0.25x + 0.65y = 36
Solve x + y = 80 for x.
x = 80 - y
Then Substitute into the second equation.
0.25(80 - y) + 0.65y = 36
20 - 0.25y + 0.65y = 36
0.4y = 16
y = 40
x + y = 80
x + 40 = 80
x = 40
Therefore, The numbers of liters that is needed is 40 liters of 25% solution and 40 liters of 65% solution.

Finals are often 20% to 40% of your final grade. If your class require that you take a final and you don’t take it, you’d get a 0.. which would put a pretty big dent in your average. If you missed all of your finals, it would most likely hurt your GPA as well.
