Answer:
B
Explanation:
The nucleus is made up of protons and neutrons, and electrons float around the neucleus in the electron cloud.
Some of the early planetesimals that formed the solar system still survive in the asteroid and Kuiper belts.
Asteroids are the rocky leftover planetesimals of the internal solar device. Planetesimals shape in protoplanetary disks, many develop into big planets, whilst others do no longer get that possibility. in the solar gadget, remnant planetesimals and minor planets inhabit the asteroid belt, Kuiper belt, Oort cloud, and different solid niches.
After the planets had been shaped, their gravity hurled most of the last planetesimals into the solar or into remote orbits around it. Phobos and Deimos are believed to be planetesimals that were captured through Mars gravity and became satellites. many of Jupiter's moons are believed to be planetesimals as well. Planetesimals are very precious to scientists because they are able to offer information approximately the introduction of our solar gadget
A planetesimal is small our bodies from which a planet originated in the early stages of formation of the solar system. Protoplanets are while planetesimals join together thru collisions and via the force of gravity to form larger our bodies

Answer:
The correct answer is a rarefaction.
Explanation:
Sound waves are longitudinal waves that propagate in a medium, such as air. As the vibration continues, a series of successive condensations and rarefactions form and propagate from it. The pattern created in the air is something like a sinusoidal curve to represent a sound wave.
There are peaks in the sine wave at the points where the sound wave has condensations and valleys where it has rarefactions.

Answer:
The strength of the magnetic field is 
.
Explanation:
Given that,
Length of the rod, L = 1.01 m
Speed with which the rod is moving, v = 3.47 m/s
We need to find the strength of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.265 mV across the rod. When the rod is moving with some speed, an emf gets induced and it is given by :
B is magnetic field
So, the strength of the magnetic field is .
