A student has the following equipment - copper wire, nail made of iron,a battery, paperclips.How can he make an electromagnet and use it to separate a mixture of small pieces of copper and iron?

please help

Answers

The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.

A biker accelerates from Om/s to 8m/s ub 3 seconds. What is his acceleration? Isthis acceleration higher than that of a car wihich accelerates from 0 to 30m/s in
8 seconds

Answers

Answer:

The acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s². So, the acceleration of the biker is NOT HIGHER than that of the car.

Explanation:

Given that,

acceleration of biker A= ?

Initial velocity of biker Vi = Om/s

Final velocity of biker Vf = 8m/s

Time taken (t) = 3 seconds

Since acceleration is the rate of change of velocity per unit time

i.e Acceleration = (Vf - Vi) / t

A = (8m/s - 0m/s) / 3s

A = 2.67 m/s²

To know which is higher, calculate the acceleration of the car

acceleration of car A= ?

Initial velocity of car Vi = Om/s

Final velocity of car Vf = 30m/s

Time taken (t) = 8 seconds

Acceleration = (30m/s - 0m/s) / 8s

A = 30m/s / 8s

A = 3.75 m/s²

Since, the acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s², the acceleration of the biker is NOT HIGHER than that of the car.

What is the frequency of light with a wavelength of 6.33x10^-7m

Answers

Answer:

4.74\cdot 10^(14)Hz

Explanation:

The frequency of an electromagnetic wave is given by

f=(c)/(\lambda)

where

c=3.0\cdot 10^8 m/s is the speed of light

\lambda is the wavelength

For the light wave in this problem, the wavelength is

\lambda=6.33\cdot 10^(-7)m

So by using the equation above, we find its frequency:

f=(3\cdot 10^8 m/s)/(6.33\cdot 10^(-7) m)=4.74\cdot 10^(14)Hz

Final answer:

The frequency of light can be found by using the formula f = c ÷ λ, where c is the speed of light and λ is the wavelength. By substituting these values into the formula, you can calculate the frequency of light with a given wavelength.

Explanation:

When you are given the wavelength of light and asked to find its frequency, you would use the formula c = fλ, where c is the speed of light (3.00 x 10⁸ m/s in vacuum), f is the frequency, and λ is the wavelength. To find the frequency, we rearrange this formula to get f = c ÷ λ. Given the wavelength λ = 6.33 x 10^-7 m, we can substitute these values into the rearranged formula to find the frequency:

f = (3.00 x 10⁸ m/s)  ÷  (6.33 x 10^-7 m)

By calculating the above equation, you will find the frequency of the light with the given wavelength.

If the angular displacement= 3t²+2t,find the angular velocity and angular acceleration​

Answers

Hi there!

The angular velocity is equivalent to:

\omega(t) = \theta'(t) = (d\theta)/(dt)

Take the derivative using the power rule:

w(t) = (d\theta)/(dt) =  \boxed{6t + 2}

The angular acceleration is equivalent to:

\alpha(t) = (d\omega)/(dt)

Differentiate once again:

\boxed{\alpha(t) = 6}

Why does cupping your hand around your ear improve your hearing?

Answers

it allows your ears to receive more sound waves

Answer:

Catch the wave.

The shape and curves are designed to capture sound waves from various directions and funnel them into the ear to start vibrating those ossicles. Cupping your hand behind the ear and pulling it forward makes sounds louder because your hand is snagging more sound waves.

Explanation:

It will receive more sounds
