Answer:
saving and consumption are influenced primarily by real current disposable income
Explanation:
keynesian economics is a known form of economics that is of demand-side in the sense that it encourages government action to increase and decrease demand and output.
Consumption is using ur money by spending it on new goods and services out of a household's current income.
While Saving is simply not eating up or the act of not consuming all of one's current income. Keynes argument was that the interest rate is not the most necessary factor in saving and consumption decisions. Rather, real saving and consumption decisions depend primarily on a household's real disposable income
Answer:
Interest Rates
<em>The first factor is the most obvious: the interest rate. Naturally, a low rate will cost you less—our numbers indicate a $10,000 balance with a 5.9% interest rate will cost $10,637 in total if paid off in 2 years.</em>
<em>That may not sound too bad, but bear in mind that 5.9% interest is extraordinarily difficult to get these days. Even people with excellent credit scores will likely pay “double digit” interest rates of over 10%. And if you’re paying a more typical 12.9% in interest on that same $10,000, you’ll pay a total of $12,797 over the same 2 years.</em>

Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F = 
where T= tension, m=mass, L=length
F = 
= 297.04/0.786
frequency =377.86Hz
