If the cruising speed of a typical passenger jet is 500 mi/hr, calculate the time required, in years, of reaching the Sun from Earth in a passenger jet. Assume the jet could actually make the journey!

21.22 years.

Explanation:

Here we can simply use the relation:

Time = Distance/Speed.

We know that the speed of the passenger jet is 500mi/hr.

And the average distance between Earth and the Sun in miles is:

Distance = 92,955,807 miles

Then the time needed to travel that distance will be:

Time = (92,955,807 miles)/500mi/hr = 185,911.614 hours.

But we want this in years.

We know that in one day, we have 24 hours, then this time in days is:

Time = (185,911.614/24) days = 7,746.3 days.

And in one year we have 365 days, then this time in years is:

Time = (7,746.3/365) years = 21.22 years.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
