The gravitational force of the Earth attracts a falling apple towards it.
The acceleration due to the Earth’s mass is much larger than the acceleration due to the apple’s mass, making the motion of the Earth practically imperceptible compared to the motion of the falling apple.
The true statement for sound waves is at 0 °C their speed is 332 meters per second. Sound waves cannot be polarized because they are longitudinal waves, and they cannot travel in a vacuum as they require a medium to ...
Sound waves are longitudinal waves. They consist of compressions and rarefactions that travel through a medium, such as air, water, or solids. Unlike transverse waves, which oscillate perpendicular to the direction of wave propagation, longitudinal waves oscillate parallel to the ...
