What is the definition of wavelength?

Back

Wavelength is the distance between successive crests of a wave, typically used in the context of sound and light waves.

Front

What does a constant speed of 55 miles per hour indicate on a graph?

Back

It indicates a straight line with a positive slope, showing that distance increases linearly over time.

Front

What is the difference between geocentric and heliocentric models of the Solar System?

Back

The geocentric model places the Earth at the center of the universe, while the heliocentric model places the Sun at the center, with planets orbiting around it.

Front

Which two human body systems are primarily responsible for oxygen transport?

Back

The circulatory system and the respiratory system work together to transport oxygen to cells.

Front

What is the significance of Earth's revolution?

Back

Earth's revolution around the Sun is responsible for the changing seasons throughout the year.

Front

What does a graph representing constant speed look like?

Back

A graph of constant speed is a straight line that slopes upwards, indicating a consistent increase in distance over time.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from the rest position to the crest or trough.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement of the medium from its rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the minimum displacement of the medium from its rest position.

Front

How does the circulatory system function in relation to the respiratory system?

Back

The circulatory system transports oxygen from the lungs to the body's cells and returns carbon dioxide from the cells back to the lungs.
