Hello!
Here is your answer:
Yes, it's correct, it is Googl.
I hope I could help!
Explanation:
The aggregate demand curve is downward sloping. It implies price levels are falling and the quantity of output will increase as well as the domestic income. The theories that can explain why the aggregate demand curve is downward sloping: the Pigou's wealth effect, the Keynes's interest-rate effect, and the and Mundell-Fleming's exchange-rate effect.

Explanation:

In equation (a) multiply by 2 then subtract from the equation (b):

put the value of x in equation (a):

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
