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.

Two bowling balls each have a mass of 8.3 kg. They are located next to each other with their centers 0.165 m apart. What gravitational force do they exert on each other
Hello!
We can use the equation of Newton's Law of Universal Gravitation to solve for the Force of Gravity:
[tex]F_g = \frac{Gm_1m_2}{r^2}[/tex]
Fg = Gravitational Force (N)
G = Gravitational Constant (6.67 × 10⁻¹¹ Nm²/kg²)
m1, m2 = masses (both 8.3 kg in this situation)
r = distance between the center of masses of the objects (0.165 m)
Plug in the given values and solve.
[tex]F_g = \frac{(6.67 \times 10^{-11})(8.3)(8.3)}{(0.165^2)} = \boxed{1.6878 \times 10^{-7} N}[/tex]

Describe how work done is related to a change in volume of a fluid. 100 points
Answer: work is the pressure acting through the change in volume
Explanation:
In the same way that work is defined as force operating over a distance, work is the pressure acting through the change in volume. Pressure is comparable to force in pressure–volume work, while volume is analogous to distance in the classic definition of work.
Just as we say that work force acting over a distance,for fluids,we can say that work is the pressure acting through the change in volume. for pressure- volume work, pressure is analogous to force, and the traditional defination of work.

The finger-like outgrowths of Amoeba helps to ingest food. However, the outgrowths of human intestine help to
(a) digest the fatty food substances (b) make the food soluble
(c) absorb the digested food (d) absorb the undigested food
(c) absorb the digested food
Explanation:
It is called villi' in case of human beings.. That's it..
The finger-like outgrowths in the human intestine are called villi, and their main function is to absorb the digested food. Therefore, the option is (c) absorb the digested food.
What is the function of villi in human ?The villi in the human intestine increase the surface area for absorption, allowing for more efficient uptake of nutrients from the digested food. They contain blood vessels and lymphatic vessels that absorb nutrients such as sugars, amino acids, and fatty acids. The nutrients are then transported to the liver and other parts of the body for use.
The function of villi in humans is to increase the surface area of the small intestine, which allows for more efficient absorption of nutrients from digested food.
Villi are finger-like projections that line the walls of the small intestine, and they are covered in tiny microvilli that further increase the surface area. The villi contain blood vessels and lymphatic vessels that absorb nutrients such as sugars, amino acids, and fatty acids from the digested food.
These nutrients are then transported to the liver and other parts of the body for use. Without villi, the surface area of the small intestine would be much smaller, and the body would not be able to absorb nutrients as efficiently. Hence, option C is correct.

A massless string connects a 10.00 kg mass to a 13.00 kg cart which is resting on a frictionless horizontal surface. The mass hangs over a frictionless pulley. When the mass is released, the cart accelerates to the right. What is the cart’s acceleration? The cart's acceleration is m/s^2. (round to one decimal place)
The cart's acceleration to the right after the mass is released is determined as 7.54 m/s².
Acceleration of the cart
The acceleration of the cart is determined from the net force acting on the mass-cart system.
Upward force = Downward force
ma = mg
13a = 10(9.8)
13a = 98
a = 98/13
a = 7.54 m/s²
Thus, the cart's acceleration to the right after the mass is released is determined as 7.54 m/s².

2.One car with a mass of 400kg is traveling east at 20m/s and collides with a car of mass 800kg traveling west at 15m/s. Assuming the collision is completely inellastic, what is velocity of the first car after the collision?
Answer:
3.33 m/s west
Explanation:
East is the positive direction.
400kg*20m/s + 800kg*-15m/s =(400kg+800kg)*v
-4000kgm/s=1200kg*v
v=-3.33
400kg*20m/s + 800kg*-15m/s =(400kg+800kg)*v. -4000kgm/s=1200kg*v and v=-3.33.
What is Collision?Collision, which is also known as impact, is the abrupt, powerful coming together in close proximity of two bodies, such as two pool cues, a golf club and a ball, a hammer and a nail, two railroad cars when linked, or a falling object and a floor.
Two factors—the force and the amount of time the items are in contact—affect the outcome of impact in addition to the characteristics of the two objects' materials.
A hard steel ball dropped on a steel plate will typically rebound to almost the same location from whence it was dropped, while a putty or lead ball would not.
Therefore, 400kg*20m/s + 800kg*-15m/s =(400kg+800kg)*v. -4000kgm/s=1200kg*v and v=-3.33.
