can a magnet attract a pure substance?
Answer:
Magnets strongly attract materials which already themselves have magnetic domains. They do not significantly attract many metals like gold, aluminum, silver, and even some types of high-chromium stainless-steel, which lack such domains. In fact, pure gold is slightly repelled.

Because of surface tension, a liquid _____.
resists flowing
forms a crystalline solid
takes the shape of its container
forms droplets
Because of surface tension, a liquid forms droplets. The surface tension makes the surface molecules experiences a strain from the bulk of the liquid.
What is surface tension ?Surface tension is the propensity for liquid surfaces that are at rest to condense into the smallest surface area. Razor blades and insects, which have a higher density than water, can float on the surface of the water without even becoming partially buried because to surface tension.
Force per unit length or energy per unit area are the dimensions of surface tension. The two are equivalent, although when discussing energy per unit of area, surface energy is frequently used because it is a more inclusive phrase that includes solids.
To minimize the surface area, liquids assume the shape of droplets. The uneven cohesive forces of the surface layer tend to pull water droplets into a spherical shape, even though they can be easily distorted. Hence, option d is correct.

A student jogs for a mile when their heartbeat starts racing and the student feels too fatigued to keep jogging. The student stopped to rest in response to the body's —
A. external stimulus of fatigue.
B. external stimulus of traveling a mile.
C. internal stimulus of sweating.
D. internal stimulus of a increased heart rate.
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.

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.
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.
