A 24 cm radius aluminum ball is immersed in water. Calculate the thrust you suffer and the force. Knowing that the density of al
Illusion [34]

Answer:

W =1562.53 N

Explanation:

It is given that,

Radius of the aluminium ball, r = 24 cm = 0.24 m

The density of Aluminium, d=2698.4\ kg/m^3

We need to find the thrust and the force. The mass of the liquid displaced is given by :

m=dV

V is volume

Weight of the displaced liquid

W = mg

W=dVg

So,

W=dg\times \dfrac{4}{3}\pi r^3\\\\W=2698.4\times 10\times \dfrac{4}{3}\times \pi \times (0.24)^3\\\\W=1562.53\ N

So, the thrust and the force is 1562.53 N.

What are some of the useful properties of current electricity?
Elena-2011 [213]

By definition we have to:

The electric current is the flow of electric charge due to the movement (usually of electrons) that a material travels.

Some properties are:

1) Electric conduction: The conductive materials have a large amount of free electrons, therefore, the passage of electricity is possible.

2) The current inside a circuit is directly proportional to the voltage and inversely proportional to the resistance of the circuit. This is what is known as ohm's law:

I =\frac{V}{R}

3) The current can be continuous or alternate.

Alternating current is the electric current in which the magnitude and direction vary cyclically.

The direct current is the flow of electric charges that does not change direction with time.

The energy produced by the internal motion of atoms? electrical , thermal, chemical, nuclear
alekssr [168]

Answer:

Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in the movement of objects. so the answer is thermal energy
