Explanation:
1: light being emitted from a light bulb is called electromagnetic waves ; transverse wave.
2: sound coming from a violin is a mechanical wave ; longitudinal wave.
3: a rock being dropped in a pond is a mechanical wave ; and im pretty sure its longitudinal and/or transverse.
(1) Light emitted from a light bulb is an electromagnetic wave i.e transverse wave. (2) sound coming from a violin is a mechanical wave i.e longitudinal wave. (3) Rock dropped in a pond is a mechanical wave i.e transverse wave.
What is a wave?In physics, a wave is a disturbance that travels through space or a medium, transferring energy without permanently displacing the medium itself. Waves can take many different forms, including mechanical waves, electromagnetic waves, and quantum mechanical waves.
Mechanical waves require a medium, such as air or water, to propagate through, while electromagnetic waves can travel through a vacuum. Mechanical waves transfer energy through the medium by causing it to oscillate, while electromagnetic waves transfer energy through oscillating electric and magnetic fields.
Waves can be described by various characteristics, such as their amplitude, wavelength, frequency, and speed. The amplitude is the maximum displacement of the wave from its equilibrium position, while the wavelength is the distance between two consecutive points on the wave that is in phase. The frequency is the number of waves that pass a point in one second, while the speed is the rate at which the wave travels through the medium.
Waves are important in many areas of physics, including optics, acoustics, and quantum mechanics. They play a crucial role in our understanding of light, sound, and the behavior of particles at the quantum level.
The sound coming from a violin is a longitudinal wave.
longitudinal waves are waves in which the oscillations of the medium are parallel to the direction of propagation of the wave. Examples of longitudinal waves include sound waves and seismic waves.
The waves created by a rock being dropped in a pond and Light emitted from a light bulb are transverse waves.
Transverse waves are waves in which the direction of the oscillations of the medium is perpendicular to the direction of propagation of the wave. In the case of water waves created by a falling rock, the oscillations of the water molecules are up-and-down, which is perpendicular to the direction of propagation of the wave.
Therefore, the light from the bulb ( electromagnetic) and rock dropped in water(mechanical ) is a transverse wave whereas The sound coming from a violin (mechanical ) is a longitudinal wave.

Explanation:
[character limit pass]
Image C represents a surface wave where wave passes through a water surface.
What is a surface wave?A surface wave is a mechanical wave that travels along the boundary between two different mediums in physics. Gravity waves on the surface of liquids, like ocean waves, are a typical example. At the boundary between two liquids with varying densities, gravity waves can also form inside liquids.
Rayleigh or Love waves are examples of elastic surface waves that can move across the surface of solids. In order to travel along a gradient in refractive index or along the interface between two mediums with differing dielectric constants, electromagnetic waves can also travel as "surface waves." A ground wave in radio communication is a guided wave that travels close to the Earth's surface.

B. external stimulus of traveling a mile.
C. internal stimulus of sweating.
D. internal stimulus of a increased heart rate.
Answers
The student stopped to rest in response to the body's internal stimulus of a increased heart rate. That is option D.
What is heart rate?The heart rate is defined as the number of times the heart beats per minute. Depending on the state of the body it can increase or decrease per minute time
During exercise, the heart rate increases during exercise because the body need more oxygen which can be gotten by increased cardiac output.
Therefore, The student stopped to rest in response to the body's internal stimulus of a increased heart rate.
