Answer:
0J
Explanation:
Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,
mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;
M1U1 + M2U2 = V (M1 + M2)
(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)
2 -2 = V (1.5)
0 = V (1.5)
divide both side by 1.5
0/1.5 = V 1.5/1.5
V = 0
since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero
1/2 V(M1 +M2)
1/2 ×0 × 1.5 = 0J
Land and water differ into the absorption and releasing of heat, the land heats up quicker than the water, and the land also cools off quicker than the water. So when the air is hotter over the land (during the day), then the air masses are moving from the sea to the land cause they are cooler and heavier. When the air is cooler over the land (during the night), then the air masses move from the land towards the water.

His career illustrates the possibilities for diffusion and intermingling of cultures brought about by the Mongol conquests. hope this helps
The two statements which are necessary to make the conclusion in the beginning of the question true include:
b) Ben is in the pool.
d) All the boys in the pool are swimming.
<h3>What is Conclusion?</h3>
This is referred to as the final or concluding part of something or an essay and usually contains the summary.
For it to be true that Ben is swimming then he has to be in the pool and all the boys present must be swimming for us to arrive at such conclusion.
