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
Scarcity-fundamental economic problem facing all societies that results from a combination of scarce resources and people's virtually unlimited wants
Answer:
The Industrial Revolution changed the way things were made as new machines invented in the 1700s and 1800s meant it was possible to mass produce goods in factories. Starting in Britain and spreading through Europe and North America, a period of rapid social and economic change began, with widespread URBANIZATION.
