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
Answer: B. A ladybug consumes aphids on a rose bush.
Reason: Predation is when one animal hunts another for food. The ladybug is consuming an aphid, which is a type of bug.
Let me know if that helps! :)
Answer:
Three benefits of the agriculture revolution that Jared Diamond lists in his argument are as follows:
- Agriculture Revolution promoted specialization in agriculture and also provide necessary time to other people who can learn other things.
- Agriculture can support economic development of the country, according to Diamond's argument.
- Diamond also raises the question on inequality between sex in agriculture, as women were thought to be meant for agriculture, which was wrong.
