Answer;
C) A solenoid is created by winding current carrying wire into a coil.
Explanation;
-A solenoid is a coil of insulated or enameled wire wound on a rod-shaped form made of solid iron, solid steel, or powdered iron.
-Solenoids have a wide range of applications, for instance they are used as electromagnets, as inductors in electronic circuits, and as miniature wireless receiving antennas.
Using Newton's second law of motion, if the net force on a sled is tripled and the mass halved, the new acceleration would be 12 m/s².
The subject of this question is derived from the principle of Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This can be represented as: F=ma (Force = mass * acceleration).
Given that the original acceleration 'a' is 2 m/s², the force 'F' acting on the sled can be calculated as F=ma. But since the net force is being tripled and the mass halved, the new force would be 3F, and the new mass would be m/2.
Now we need to determine the new acceleration, which can be calculated as a = F/m. Plugging in our new values, we get a = (3F)/(m/2). This equates to a = 6F/m. Since the original force is calculated as F=ma, we can substitute this in the above equation. Hence the new acceleration is 6*2 m/s² = 12 m/s².

Answer:
Infrasound vs. Ultrasound: Infrasound is sound that is below the lower limit of human hearing, below 20 Hz, and ultrasound is above the upper limit of human hearing, above 20,000 Hz. Individuals use infrasound - this recurrence run for checking seismic tremors and volcanoes, graphing rock and oil developments underneath the earth. Infrasound is described by a capacity to get around hindrances with little scattering.
For instance, a few creatures, for example, whales, elephants and giraffes convey utilizing infrasound over significant distances. Torrential slides, volcanoes, seismic tremors, sea waves, water falls and meteors produce infrasonic waves. Symptomatic ultrasound, additionally called sonography or demonstrative clinical sonography, is an imaging technique that utilizes high-recurrence sound waves to create pictures of structures inside your body. The pictures can give important data to diagnosing and treating an assortment of ailments and conditions.
