Your students may appreciate a demonstration that stretching and relaxing an "instrument" will raise and lower its pitch. Consider doing one of the following:

  • The simplest way to demonstrate this is with rubber bands. Let one student stretch a rubber band between two fingers while another student plucks it. Listen to the sound the rubber band makes; the tighter it is stretched, the higher the sound. If it is stretched or relaxed quickly immediately after being plucked, you may even be able to hear the pitch slide up or down, just like it does in a talking drum.
  • Many hobby books on making musical instruments include instructions for making a drum with a stretched head held in place by strings. If it is made of good materials, you should be able to change the pitch of such a drum by tightening or loosening the strings. Pursue this only if you are interested in a major class project which will require specific materials and take several hours.
  • You may be able to get a local band director or percussionist to bring in some drums with heads that can be tightened and loosened to change the pitch. Ask for a demonstration, and an explanation of the methods of tightening and loosening drum heads. Many percussionists won't have a waisted drum, but many other drums (such as orchestral tympani) are also "tunable".
  • The basic idea can also be demonstrated with any stringed instrument (guitar, violin, banjo, cello, etc.): as you turn the tuning peg you are winding or unwinding the string, making it tighter or looser.

Activity: tonal languages

    Objectives and standards

  • Objectives - Students will actively participate in a demonstration of how tonality affects meaning even in a nontonal language, by demonstrating and explaining how different inflections cause slight differences in the meaning of a short word or phrase in English.
  • Music Standards Addressed - National Standards for Music Education standards 8 (understanding relationships between music, the other arts, and disciplines outside the arts) and 9 (understanding music in relation to history and culture).
  • Other Subjects Addressed - The activity also addresses National Standards in the Social Studies standard 1 (culture), and National Standards for the English Language Arts standards 4 (Students adjust their use of spoken, written, and visual language (e.g., conventions, style, vocabulary) to communicate effectively with a variety of audiences and for different purposes.) and 9 (Students develop an understanding of and respect for diversity in language use, patterns, and dialects across cultures, ethnic groups, geographic regions, and social roles).
  • Evaluation - Assess student learning by evaluating class participation or asking relevant questions in an oral review or on a written test: e.g. "What is a tonal language?"
  • Adaptations - For best comprehension, this activity should be presented to students using their native language, dialect, and accent. The teacher should adjust the activity accordingly.

English is not a tonal language, so it can be difficult for English speakers to appreciate how important inflection is in tonal languages. Here is a short activity that can help and requires no materials or preparation.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
