if nominal gdp is 1800 and the money supply is 450, then what is velocity?
Answer:
Explanation:
answer: 4 velocity.
if nominal gdp is 1800 and the money supply is 450, then what is velocity?
4 velocity.
If the nominal GDP is 1800 and the money supply is 450, then the velocity of money would be 4.
The total value of goods and services generated in an economy during a given time period, usually a year, is referred to as nominal GDP and is not adjusted for inflation. It depicts what products and services are now selling on the market.
Given:
Nominal GDP, PQ = 1800
Money supply, M = 450
From equation of exchange:
MV = PQ
V = (PQ) ÷ M
V = (1800) ÷ (450)
V = 4
Hence, if the nominal GDP is 1800 and the money supply is 450, then the velocity of money would be 4.

An airplane is flying in a horizontal circle at a speed of 490 km/h. If its wings are tilted at angle ɵ = 45° to the horizontal, what is the radius of the circle in which the plane is flying? Assume that the required force is provided entirely by an “aerodynamic lift” that is perpendicular to the wing surface.
The radius of the circle in which the plane is flying is 1887 m.
What is aerodynamic lift?The aerodynamic lift is the force that keeps the aircraft flying in the air.
Let the aerodynamic lift be F1 sinθ= mv^2/R ---- (1)
and F1 cosθ= mg --------- (2)
Equating (1) and (2) and eliminating the mass;
R = v^2/ g tanθ
Where v = 490 km/h or 136 m/s
R = (136)^2/9.8 * tan 45
R = 18496/ 9.8

a force of 50 N directed 30 degrees above the horizontal is applied to a 10 kg block at rest on a rough horizontal surface. what is the coefficient of kinetic friction between the block and the horizontalsurface if the acceleration of the block is 20 m/s^2
The coefficient of kinetic friction between the block and the horizontal surface will be 1.597.
What is kinetic friction?A force that acts among sliding parts is referred to as kinetic friction. A body moving on the surface is subjected to a force that opposes its progressive motion.
The given data in the problem is;
μ is the coefficient of kinetic friction=?
m is the mass of the block=10 kg
g is the acceleration due to gravity= 9.81 m/s²
Acceleration of block(a)=20 m/s²
Force (F)= 50 N
θ=30°
There are two forces to act on the block, one is the force directed while the other was the friction force opposing the motion.
From the newton's second law;
F= ma
F-f = ma
Fcos30°- μmg=ma
50cos 30°-μ× 10×9.81 =10 × 20
μ= 1.597
