Suppose a tank filled with water has a liquid column with a height of 19 meter. If the area is 2 square meters 2m squared, what’

s the force of gravity acting on the column of water?
Physics
1 answer:
ycow [4]3 years ago
4 0

Answer:

  372,400 N

Explanation:

The volume of the column is ...

  V = Bh = (2 m^2)(19 m) = 38 m^3

If we assume the density is 1000 kg/m^3, then the mass of the water is ...

  M = ρV = (1000 kg/m^3)(38 m^3) = 38,000 kg

The force of gravity on that mass is ...

  F = Mg = (38,000 kg)(9.8 m/s^2) = 372,400 N

A type of energy embodied in oscillating electric and magnetic fields is called
yaroslaw [1]

Answer: Electromagnetic radiation

Explanation:

Electromagnetic radiation is a combination of oscillating electric and magnetic fields, which propagate through space carrying energy from one place to another.

To understand it better:

This radiation is spread thanks to the electromagnetic fields produced by moving electric charges and their sources can be natural or man-made.

It should be noted that the energy of electromagnetic radiation can vary and depending on its frequency it can be useful for various situations.

How many cubic objects of volume 2cm cube can be started in a room of dimension 2m by 3m by 4m​
jenyasd209 [6]

Answer:

12,000,000 boxes

Explanation:

the volume of the room can be found by using the equation for volume of a rectangular box:V=LxWxH

where:

L=2m

W=3m

H=4m

(it doesn't really matter which is which since it is multiplication)

when we multiply our values (2m*3m*4m) we get 24cubic meters

now we need to convert cubic meters to cubic centimeters

each cubic meter is 1,000,000 cubic centimeter we multiply 24 by 1,000,000 and we get: 24,000,000 cubic centimeters (cc)

dividing 24,000,000 by 2 (since each box is 2cc) we get 12,000,000

so, we know we can fit 12,000,000, 2 cubic centimeter boxes in this room

A ball was thrown from a projectile building of 30m which moves at a constant velocity of 20m/s and has an angle of 30degrees to
qwelly [4]

Answer:

Time of flight = 4.08seconds

Horizontal component of initial velocity is 17.32m/s

Explanation: complete question( and the horizontal component of the initial velocity.)

The equation for time of flight of a projectile is given as T= 2u/g

T=( 2×20)/9.8

T= 40/9.8= 4.08seconds

Horizontal component of initial velocity Vix= Vi Costheta

Vix= 20× cos 30°

Vix= 20×0.8660

Vix= 17.32m/s
