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
If the money supply increases and nominal GDP remains the same, then A. price level increases.
<h3>What is Money Supply?</h3>
This refers to the total amount of money that is in circulation in a country that usually increases spending.
Hence, an open market sale by the federal reserve will increase the interest rates because it would increase investment spending because an OMO sale decreases interest rates which make getting loans easier.
M= Money supply
V= Velocity
P- Price level
Y= nominal GDP
Hence, with the increase in the money supply, then there would be an increase in the price supply.

Hi there
The formula is
A=p (1+rt)
We need to solve for t
T=[(A/p)-1]÷r
Where
A future value 2200
P present value 1000
R interest rate 0.08
T time?
So
T=((2,200÷1,000)−1)÷0.08
T=15 years
Another time like this question you should post in at mathematics subject
Hope it helps
