In a stringed musical instrument, the sound frequency of a particular string can be increased by A. tightening the string.
B. increasing the string's thickness.
C. loosening the string.
D. lengthening the string.

Answers

Answer 1
Answer: The answer is A: tightening the string. By doing this, the string will become slightly shorter. A shorter string, when plucked or bowed, will produce a higher pitch. The other answers will have different results. Increasing the thickness, loosening the string, and lengthening the string will all cause the pitch to lower.
Answer 2
Answer:

In a stringed musical instrument, the sound frequency of a particular string can be increased by tightening the string (option A).

What happens to the frequency of a vibrating string

The frequency of a vibrating string determines the pitch of the sound it produces. Higher frequencies result in higher-pitched sounds, while lower frequencies produce lower-pitched sounds.

By tightening the string, the tension in the string increases. This increased tension leads to an increase in the frequency of vibration of the string when plucked, bowed, or struck. As a result, the pitch of the sound produced by the string becomes higher. Option A is therefore correct.

What is used to create sounds of different pitches and tones by musicians?

Answers

The answer to the question that is being presented above would be musical instruments. These instruments are used to create sounds of different pitches and tones by musicians. They operate through being striked or 'sawed' to create vibrations that produce sound.

When Anna eats an apple, the sugars in that apple are broken down into the substance called glucose. Glucose is then burned in her body for energy. One of the body parts that needs this energy is the heart, which beats due to electrical impulses. A byproduct of this glucose breakdown is the heat that warms her body and is later released.Which identifies the energy transformations that take place in Anna’s body as this process takes place?

A: Mechanical energy is converted to kinetic energy, which is then converted to potential energy.
B: Chemical energy is converted to thermal energy and electrical energy.
C: Electrical energy is converted to chemical energy and thermal energy.
D: Mechanical energy is converted to potential energy which is then converted to kinetic energy.

Answers

The correct answer is

B: Chemical energy is converted to thermal energy and electrical energy.

In fact:

- initially, the energy is contained in the molecular bonds of the glucose, inside the sugars that Anna is eating, and this energy is in the form of chemical energy

- Part of this energy is converted into the electrical energy that make the heart beating, and this energy is in the form of electrical energy

- The rest of the energy is converted into heat for the body, and this energy is in the form of thermal energy

Answer: B. Chemical energy is converted to thermal energy and electrical energy.

TRUE OR FALSE : Boyle’s law states that, as the pressure of a gas increases, the volume decreases.

Answers


At first glance, this statement seems to be true.  But after about a
microsecond of further consideration, one realizes that the statement
would actually set Boyle spinning in his grave, and is false.

Boyle's law states that there is a firm relationship among the pressure,
temperature, and volume of an ideal gas, and that you can't say anything
about how any two of these quantities depend on each other, unless you
also say what's happening to the third one at the same time.

As the pressure of an ideal gas increases, the volume will decrease in
direct proportion to the volume, IF THE TEMPERATURE OF THE GAS
REMAINS CONSTANT.

If you wanted to, you could increase the pressure AND the volume of an
ideal gas both at the same time.  You would just need to warm it enough
while you squeeze it.

The discovery that one current-carrying wire exerts a force on a second current-carrying wire was made by _________.Coulomb
Oersted
Faraday
Ampere

Answers

This discovery was made by Ampere. He further investigated the discovery made by Oersted. Ampere lead to the realization that two parallel wires that carry current exert a force upon each other. He further discovered that when the currents in two wires are in the same direction they are attracted to each other while when the currents are in the opposite directions they are attracted.
