Two small children decide it would be fun to toss a couple of large cats at each other. Cat A (7kg) is thrown at 7m/s and cat B

(6.1kg) is thrown at 2m/s. When they collide the cats stick together. How fast is the cat mess going after the collision?

Answer:

V=4.7m/s

Explanations:

Let Ma mass of cat A=7kg

Va velocity of cat A=7m/s

Mb mass of cat b=6.1kg

VB velocity of cat b=2m/s

From conservation of linear momentum

MaVa+MbVb=(Ma+Mb)V

7*7+6.1*2=(7+6.1)V

61.2=13.1V

V=4.7m/s

Velocity is:
sleet_krkn [62]

Answer:

d

Explanation:

Solution:-

- The Quantity of theory of money states:

                      M * V = P * Y

Where,

           M = Money supply

           V = Velocity of money exchange

           P = The price level

           Y = Real GDP

- By re-arranging the formula and solving for "V" we have:

                     V = P*Y / M

- The expression on right hand side increases if exchange of dollars increases.

Irina18 [472]

In order from shortest to longest frequency, the electromagnetic waves can be ranked :

1. X-rays

2. Ultraviolet

3. Infrared

4. Microwave

X-rays has the shortest frequency which ranges between 30 petahertz to 30 exahertz. X-rays have the smallest wavelengths at 0.01-10 nanometers. Its energy ranges between 100eV to 100keV.
