Speed of sound inside aircraft

Sound

November 21, 2019

Question

Disabled veteran with PTSD, my brain turned on at 5 a.m. today with the idiot question of what is the speed of sound inside an aircraft flying faster than sound. Wide awake now, I assume that the speed is relative to the enclosing vessel, and that the speed of the aircraft is essentially irrelevant. Except possibly at lightspeed ...

Karen - USA (29274)

Answer

That is a good question, and you are correct that the speed of sound inside an enclosed aircraft is independent of the aircraft's external speed.

Question

what is the method of calculating simple pendulum

MAUAN - Nigeria (29272)

You can measure the frequency that a pendulum swings with a stopwatch.

To calculate the frequency, you must measure the length of the rod or wire and use the equation: f = [SQRT(g/L)]/2PI.

Suggested Resource from Students

Education

November 6, 2019

Question

I am Judy from MyAfterSchoolEducation in Brighton, UK. This summer, August was devoted to astronomy and stargazing. Firstly, all students had to do their own research on the solar system to “Make their own solar system” and later to identify and mark as many visible constellations on a printed star map (provided by me).

Among the many resources the kids found online, they really liked your page https://www.school-for-champions.com/education/resources.htm and as a thank you for the time you put to create it, they asked me to share with you the following very useful guide. “Parents guide to our Solar System”, https://www.homeadviceguide.com/parents-guide-to-solar-system/.”

Would you mind adding it on your web site? My students will be thrilled to know that you liked their suggestion.

Judy - UK (29259)

Answer

Thanks for the suggested resource from your students. I added a link at: https://www.school-for-champions.com/education/resources.htm#Parents

Wants to pass a tough class

Grades

October 21, 2019

Question

I need help! I am 68-years-old and for some unknown reason decide to go back to the university and a Post-Master’s degree in Geriatrics and one of the courses is Advance Practice Pharmacotherapeutics. I am struggling - there is so much material and very difficult. I need an 80 yo pass the course and at te moment I have a 75.2 average. How can I better study and retain the material? Please help!

Marlene - USA (29229)

Answer

Congratulations on going back to school and seeking an advanced degree, especially in something like Advance Practice Pharmacotherapeutics. It can be tough for young students as well as those who are older like yourself.

It is good that you are looking around for some help in getting through the class.

Certainly, you need to take notes in class and to organize your work and time. Setting aside a certain amount of time to study with no interruptions can help.

Also not that teachers of give hints about what is important and will be in the tests.

If you can, try to get some pointers from your professor about things you are having trouble understanding. Perhaps seek a mentor or some assistance.

Showing that you really want to do well in the class can help.

Best wishes for success in learning the material and in getting a passing grade in this class.

Sound of sea is louder at night

Physics

October 8, 2019

Question

Why sound of sea is louder at night than day time???

Nahida - Pakistan (29214)

Answer

The loudness or amplitude of sound increases with a reduction in temperature. The air above the sea is cooler at night and thus seems louder.

See Sound Seems Amplified Over Water for an explanation.

Affect of force

Force

October 5, 2019

Question

If we force the object it will change its shape,size or motion

Zuhair - India (29209)

Answer

If you apply a force on an object, you can accelerate the object. But it is also possible for the force to change the shape of an object, such as when you push on a soft object. A force applied in all direction on an object can compress it and change its size.

If you placed a nonconducting object such as a plastic rod or sphere that has charges on its surface near a metal or conducting object--such as a metal rod--your can induce electrical charges in the rod. Often this effect lasts for a short time, since the charges may be drained off.
