Honors Science Exam 1st Sem. 24 25

Front

What happens to the volume of a sound wave as time passes if it is decreasing?

Back

The volume of the sound wave is becoming quieter.

Front

How is gravitational attraction related to distance between two masses?

Back

Gravitational attraction is inversely proportional to distance; as distance increases, gravitational attraction decreases.

Front

What change occurs in wavelength as you move from radio waves to gamma waves in the electromagnetic spectrum?

Back

Wavelength decreases.

Front

In an IF/THEN statement, what are the roles of the independent and dependent variables?

Back

The independent variable is what you change, and the dependent variable is what you measure.

Front

What does it mean to encode a message?

Back

To encode a message means to convert information into a format suitable for transmission.

Front

What does it mean to decode a message?

Back

To decode a message means to convert the received information back into a format that is understandable.

Front

What is the relationship between pitch and frequency in sound waves?

Back

Pitch is directly related to frequency; higher frequency results in a higher pitch.

Front

What is the definition of a controlled variable in an experiment?

Back

A controlled variable is a factor that is kept constant to ensure that the results are due to the independent variable.

Front

What is the significance of the electromagnetic spectrum?

Back

The electromagnetic spectrum encompasses all types of electromagnetic radiation, ranging from radio waves to gamma rays.

Front

How does the concept of energy relate to sound waves?

Back

Sound waves carry energy through vibrations of particles in a medium.
