Thank you!!!! :D

Answer:

answer in the explanation!!

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.

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.

A physics teacher performed a demonstration for a science class by pulling a crate across the floor and measuring the force with a spring scale. While she pulled, a student measured the acceleration of the crate with a handheld electronic device. The results of three trials are shown below. The teacher asked the class to calculate the acceleration of the crate based on the crate’s mass and the force she applied. What conclusion can be made about the difference between the CALCULATED acceleration and the ACTUAL acceleration that occurred in the trials?

Read the excerpt from "The Monkey's Paw.”

"It had a spell put on it by an old fakir," said the sergeant-major, "a very holy man. He wanted to show that fate ruled people's lives, and that those who interfered with it did so to their sorrow. He put a spell on it so that three separate men could each have three wishes from it."

His manner was so impressive that his hearers were conscious that their light laughter jarred somewhat.

"Well, why don't you have three, sir?" said Herbert White, cleverly.

The soldier regarded him in the way that middle age is wont to regard presumptuous youth. "I have," he said, quietly, and his blotchy face whitened.

"And did you really have the three wishes granted?" asked Mrs. White.

"I did," said the sergeant-major, and his glass tapped against his strong teeth.

"And has anybody else wished?" persisted the old lady.

"The first man had his three wishes. Yes," was the reply; "I don't know what the first two were, but the third was for death. That's how I got the paw."


Which event does the excerpt foreshadow?


A. the sergeant-major's return to India and the resulting tragedy

B. the sergeant-major obtaining the paw and the resulting tragedy

C. Mr. White's refusal of the paw and the resulting tragedy

D. Mr. White accepting the paw and the resulting tragedy
