A long solenoid that has 1000 turns uniformly distributed over a length of 0.400 m produces a magnetic field of magnitude 1.00 ×

yKpoI14uk [10]

0.03185A current is required in the windings for that to occur.

Solenoids are essentially coils of cord. These generate a magnetic subject which strives a pressure over a steel element.A solenoid is a fundamental time period for a coil of cord that we use as an electromagnet.
We additionally consult with the tool which could convert electric power into mechanical power as a solenoid.

Actually it generates a magnetic subject for developing linear movement from the electrical cutting-edge. With using a magnetic subject.

Magnetic field at the centre of a solenoid of length 'L' having 'N' number of turns with a current 'I' is given by $B=\frac{u_0NI}{L}$ ...(1)

It is given that 1000 turns uniformly distributed over a length of 0.400 m produces a magnetic field of magnitude 1.00 ×10⁻⁴T .

Putting above values in equation (1) , we get

$1.00\times10^{-4}=\frac{4\pi \times10^{-7}\times1000I}{0.400} \\\\I=\frac{1.00\times10^{-4} \times0.400}{4\pi \times1000} \\\\I=0.03185A$

The chart show the masses and velocities of two colliding objects that stick together after a collision.

finlep [7]

Answer:

1,500 kg.m/s

Explanation:

First, arrange the information in a table:

Object Mass (kg) Velocity (m/s)

A 200 15

B 150 - 10

After the collision, the two objects are stick together, thus you talk aobut one object and one momentum.

According to the law of convervation of momentum, the momentum after the collision is equal to the momentum before the collision.

Momentum before the collision, P₁:

$P_1=m_{A,1}\times v_{A,1}+m_{B,1}\times v_{B,1}$

$P_1=200kg\times 15m/s+150kg\times (-10m/s)\\\\ P_1=3000kg.m/s-1500kg.m/s=1500kg.m/s$

Momentum after the collision:

As stated, it es equal to the momentum before the collision: 1,500 kg . m/s

Explain how air masses form and how they help redistribute energy on earth surface

Anna35 [415]

Air masses form because of all the moisture in the air, and they redistribute energy on the Earth's surface because of the Sun's uneven heating on the Earth allowes more energy to Earth.

Solve the following problem showing all work, the formula, and correct units.

Temka [501]

5g/cm³

it is not iron.

Explanation:

Given parameters:

Density of iron = 7.874g/cm³

Mass of metal = 2000g

Volume of metal = 400cm³

Unknown:

Density of bar = ?

Is it iron = ?

Solution:

The density of a substance is its mass per unit area. Every substance have an intensive density value that typifies them all.

The density of water and other substances are the same if they maintain their level of pureness.

Density = $\frac{mass }{volume}$

Density of metal bar = $\frac{2000}{400}$ = 5g/cm³

Since this value is not the same as the given density of iron, it is not iron.
