Usain bolt can run the 100 m dash in 9.58 s. what is usain's average acceleration during this sprint?

Answers

Assuming Usain Bolt starts from rest (so, its initial velocity is zero), and that his motion is uniformly accelerated, his position at time t is given by
$S(t) = (1)/(2)at^2$
where a is the average acceleration and t the time. In our problem, the distance covered is S=100 m and the time taken is t=9.58 s, therefore the average acceleration can be found by re-arranging the previous formula:
$a= (2S)/(t^2)= ((2)(100 m))/((9.58 s)^2)=2.18 m/s^2$

Ksp for agbr is 5x10-13. what is the maximum concentration of silver ion that you can have in a 0.1 m solution of nabr?

Answers

Answer : The maximum concentration of silver ion is $5* 10^(-12)m$

Solution : Given,

$K_(sp)$ for AgBr = $5* 10^(-13)$

Concentration of NaBr solution = 0.1 m

The equilibrium reaction for NaBr solution is,

$NaBr(aq)\rightleftharpoons Na^++Br^-$

The concentration of NaBr solution is 0.1 m that means,

$[Na^+]=[Br^-]=0.1m$

The equilibrium reaction for AgBr is,

$AgBr\rightleftharpoons Ag^++Br^-$

At equilibrium s s

The expression for solubility product constant for AgBr is,

$K_(sp)=[Ag^+][Br^-]$

The concentration of $Ag^+$ = s

The concentration of $Br^-$ = 0.1 + s

Now put all the given values in $K_(sp)$ expression, we get

$5* 10^(-13)=(s)(0.1+s)$

By rearranging the terms, we get the value of 's'

$s=5* 10^(-12)m$

Therefore, the maximum concentration of silver ion is $5* 10^(-12)m$ .

[Br⁻¹] = [NaBr] = 0.1

Ksp = [Ag⁺] x [Br⁻]
5 x 10⁻¹³ = [Ag⁺] x 0.1
[Ag⁺] = 5 x 10⁻¹²

What is the purpose of a core in an electrmagnet

Answers

Answer:

The purpose of a core in an electromagnet is to enhance the magnetic field strength produced by the electromagnet. The core is typically made of a ferromagnetic material, such as iron or steel, that can easily magnetize and demagnetize.

When an electric current flows through a wire wrapped around the core, a magnetic field is generated. This magnetic field is concentrated and strengthened by the core material. The core acts as a pathway for the magnetic field lines to flow through, making the electromagnet stronger and more efficient.

The core helps to increase the magnetic flux density, which is the amount of magnetic field passing through a given area. By concentrating the magnetic field, the core allows the electromagnet to exert a stronger force on nearby magnetic objects, such as attracting or repelling other magnets or moving metal objects.

To visualize this, think of the core as a "magnetic conductor" that channels and focuses the magnetic field. It's like using a magnifying glass to concentrate sunlight onto a small spot, making it hotter and more intense. Similarly, the core enhances the strength of the magnetic field produced by the electromagnet.

In summary, the purpose of a core in an electromagnet is to increase the magnetic field strength by providing a pathway for the magnetic field lines to flow through. This makes the electromagnet more powerful and allows it to perform various tasks, such as lifting objects, generating electricity, or controlling mechanical devices.

Answer:

Purpose of a core in an electromagnet to increase the strength, efficiency, and size of the magnetic field.

Explanation:

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. Electromagnets usually consist of wire wound into a coil. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil.

The purpose of a core in an electromagnet is to concentrate the magnetic field.

The coil of wire that creates the magnetic field in an electromagnet is typically made of copper, which has a relatively low magnetic permeability. This means that the magnetic field lines tend to spread out in all directions, resulting in a weak magnetic field.

Some of the purposes of using a core in an electromagnet are:

To increased magnetic field strength:
The core concentrates the magnetic field, resulting in a much stronger magnetic field.
To reduced size:
The core helps to confine the magnetic field, which can reduce the size of the electromagnet.
To improved efficiency:
The core helps to direct the magnetic field, which can improve the efficiency of the electromagnet.

Overall, the core in an electromagnet plays an important role in increasing the strength, efficiency, and size of the magnetic field.
