Answer:

Force of gravity, F = 102,900 N

Explanation:

It is given that,

Height of the liquid column, h = 7 m

Area of tank, A = 1.5 m²      

We have to find the force of gravity acting on the column of water. Force of gravity is given by :

W = m g .............(1)

Where

m is the mass of an object

g is acceleration due to gravity

Firstly calculating the mass of the tank. It can be calculated suing the definition of density. We know that the density(d) of water is 1 kg/liter

Mass, m = d × V

V = volume = area × height =  1.5 m² × 7 m = 10.5 m³ or 10500 liter

So, m = 1 kg/liter × 10500 liter = 10,500 kg

Equation (1) becomes : W = 10,500 kg × 9.8 m/s²

W = 102,900 N

So, the force of gravity acting on the column of water is 102,900 N. Hence, the correct option is (b).

Which of the following statements are true concerning the creation of magnetic fields? Check all that apply. Check all that appl
anzhelika [568]

Answer:

A permanent magnet creates a magnetic field at all points in the surrounding region.

An electric current in a conductor creates a magnetic field at all points in the surrounding region.

A moving electric charge creates a magnetic field at all points in the surrounding region.

Explanation:

Magnet field is a region around the magnet in which the magnetic force can be experienced. A magnet has two poles: North pole and South pole. A Magnetic field originates from north pole and ends at south pole.

Magnets are of two types: Permanent magnet and temporary magnet.

A moving charge produces magnetic field. A stationary charge can not produce a magnetic field.

The rate of flowing charge constitutes an electric current. If the cardboard is placed around the current carrying conductor and the iron fillings spread around the cardboard then the iron nails get stick to it. It means that a current carrying conductor creates a magnetic field around it.

Therefore, the true statements from the given statements are as follows;

A permanent magnet creates a magnetic field at all points in the surrounding region.

An electric current in a conductor creates a magnetic field at all points in the surrounding region.

A moving electric charge creates a magnetic field at all points in the surrounding region.

What is the surface area to volume ratio of this cube
tamaranim1 [39]

I can't see that cube from here.

But if the length of the side of the cube is ' K ' units,
then the surface area of the cube is  6K² units², and
the volume of the cube is  K³ units³.

The ratio of the surface area to the volume is

               (6K² units²) / (K³ units³)  =  (6) / (K units) .

So for example, if the side of the cube is 2 inches, then
the ratio of surface area to volume is  "3 per inch".

That's the answer.  I did the whole thing in order to earn
the points, but I don't expect you to understand much of it,
because I see from your username that you suck at math.
I'm sorry you decided that.  Now that you've put up the
brick wall, it'll be even harder for any math to find its way
in there, and you'll miss out on a lot of the fun.
