On a part-time job, you are asked to bring a cylindrical iron rod of density 7800 kg/m3 , length 92.8 cm and diameter 2.05 cm from a storage room to a machinist, the  weight of rod w is 23.41 N .

Given ,

density (d) = 7800 kg/m³

D = 2.05 cm = 0.0205 m

r = D/2 = 0.0205 / 2 =0.01025 m

h = 92.8 cm = 0.928 m

The weight is calculated by ,

W = m × g

But, to find mass (m)

m = d × V

The volume of the rod, because is cylindrical, is,

V = π × r² × h

∴ V = 3.14 × (0.01025)² × 0.928

∴ V = 3.14 × 1.051 × 10⁻⁴ × 0.928

∴ V = 3.0625 × 10⁻⁴

Now to calculate mass,

m = d × V

∴ m = 7800 × 3.0625 × 10⁻⁴

∴ m = 2.3887 Kg

Now, for calculating weight

W = m × g

∴ W =  2.3887 × 9.8

∴ W = 23.41 N

∴ The weight of the rod W assuming the free-fall acceleration is 23.41 N .

We can determine the magnetic field over two different distances from a network made up of 2 conductors using Ampere's law:

The system's magnetic field is: B = μ₀.I/(2πr).

According to Ampere's law, the magnetic field's dot product times a closed path equals proportional to the current that flows through the path.

∫ B. ds = μ₀ I

B is the magnetic field, S is the closed channel, m is the vacuum permittivity, and I is the current where bold indicates vectors;

For the magnetic fields within the two conductors.

Fixing the associated circular path will cause I, the current which stops inside the path, to flow through the system.

The circle's diameter is

s = 2π r.

As indicated by Newton's law of attraction each article or body in the universe draws in every single item towards one another and that power of fascination is straight forwardly relative to the result of their masses and contrarily corresponding to the square of the distance between them.  

The power of gravity between two articles will diminish as the distance between them increments. The two most significant elements influencing the gravitational power between two items are their mass and the distance between their focuses. As mass increments, so does the power of gravity, however an increment in distance mirrors a reverse proportionality, which makes that power decline dramatically.

Let us note that according to the Newton's third law, action and reaction are equal and opposite. In this case, we are told that an inflated balloon released from rest moves horizontally. We know that the direction that the object moves must be in that of the applied force.

In this case, there is a horizontal force that is applied on the balloon and the effect of this force is that the balloon would have to move in the horizontal direction and this is in reaction to the horizontal force that has been applied.
