The voltage applied across 1.94 cm² wire is22.1 V

We are given that

A₁ = 0.7 cm² = 1.08*10⁻⁴ m²

A₂= 2.5 cm² = 1.94*10⁻⁴ m²

A₃= 2.2 cm² = 3.08*10⁻⁴ m²

A₄= 3 cm² = 5.06*10⁻⁴ m²

Using  1cm²=10⁻⁴ m²

We know that using resistance formula we can calculate voltage

R = ρL/A

In series

R=R₁+R₂+R₃+₄

R=ρL/{A₁+ρL/{A₂}+ρL/{A₃}+ρL/{A₄}

Substitute the values

R = ρL/(2.62*10⁴)

V = 120v

I = V/R

I = 120 / {ρL(2.62*10⁴)}

Now the voltage across can be determined.

Voltage across the 1.94 square cm wire=IR=I*(ρL/A₂)

Voltage across the 1.94 square cm wire=ρL/ 1.94*10⁻⁴=22.1 V

Voltage across the 1.94 square cm wire=22.1 V

Therefore, The voltage applied across 1.94 cm² wire is22.1 V

The separation length of induced dipole is [tex]E_{net}[/tex] =[tex]\frac{kq}{d^{2} }[/tex] ( 1 + [tex]\frac{s}{8d}[/tex] ) leftward.

What is dipole moment?

A charge separation results in dipole moments. Dipole moments are caused by changes in electronegativity and can appear in ionic bonds between two ions or covalent bonds between atoms. The dipole moment increases with increasing electronegativity disparity. Another element affecting the size of the dipole moment is the distance between the charge separations. A molecule's polarity can be determined by its dipole moment.

We have,

Electric field due to dipole = E₂

As negative charge is nearer then the electric field will be toward the dipole.

E₁ = [tex]\frac{kqs}{r^{3} }[/tex] = [tex]\frac{kqs}{(2d)^{3} }[/tex] = [tex]\frac{kqs}{8d^{3} }[/tex]

Now, electric field due to single charge -q = E₂

E₂ = [tex]\frac{kq}{r^{2} }[/tex] = [tex]\frac{kq}{d^{2} }[/tex]

[tex]E_{net}[/tex] = E₁ + E₂ = [tex]\frac{kq}{d^{2} }[/tex] ( 1 + [tex]\frac{s}{8d}[/tex])

Acceleration of this helicopter is: 7 m/sec².

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route. In other words, although velocity is a vector, speed is a scalar quantity.

Given that,

Initial Speed :- 25 m/s

Final Speed :- 60 m/s

Time :- 5 sec

Now by using motion equation ..

v = u + at

60 m/sec = 25 m/sec + (a × 5 sec)

The force applied to 6,100 kg freight truck which accelerated from 12 m/s to 37 m/s in 6.4 s is 23828.13 N.

From Newton's Second Law, force is expressed as;

F = m × a

Where is mass of object and a is the acceleration.

From the First Equation of Motion;

v = u + at

Where v is final velocity, u is initial velocity, a is acceleration and t is time elapsed.

Given the data in the question;

First, we determine the acceleration of the truck, using the first equation of motion.

v = u + at

37m/s  = 12m/s + ( a × 6.4s )

Solve for a

37m/s - 12m/s = ( a × 6.4s )

25m/s = a × 6.4s

a = 25m/s / 6.4s

a = 3.90625 m/s²

Now, we determine force applied.

F = m × a

F = 6100kg × 3.90625 m/s²

F = 23828.13 kgm/s²

F = 23828.13 N
