Answer:
A) electron
Explanation:
Matter consists of atoms. Each atom consists of three particles:
- The proton: the protons are located inside the nucleus of the atom. They have a mass of , and they have positive electric charge (). Protons are not fundamental particles, but they actually consists of three quarks (which are instead fundamental particles), in particular of 2 up quarks and 1 down quark.
- The neutron: neutrons are also located inside the nucleus. They have no electric charge, and their mass is similar to that of the proton (slightly larger). Neutrons consist of three quarks as well, in particular of 2 down quarks and 1 up quark.
- The electron: electrons are located outside the nucleus. They have a mass much smaller than protons (about ) and they have a negative electric charge, opposite to that of the proton (). The electron is a fundamental particle.
Therefore, the subatomic particle having a negative charge is
A) electron

<h2>Comet:</h2>
It is a celestial body constituted by ice, dust and rocks that orbit around the Sun, after having been altered by the Oort cloud; following different trajectories that can be highly eccentric elliptical (periodic trajectories), parabolic or hyperbolic.
One of the main characteristics of a comet is that it travels quite fast, on its way around the Sun and has a long tail, which always go in the opposite direction to the Sun (due to the radiation pressure of sunlight).
<h2>Asteroid:
</h2>
It is a small rocky body (smaller than a planet and larger than a meteoroid). Most of these bodies are orbiting between Mars and Jupiter in the region known as the asteroid belt; while others accumulate at Jupiter's Lagrange points, and others cross the orbits of the planets.
<h2>Meteoroid:
</h2>
It is a fragment of the celestial body that moves through space, which is smaller in size to an asteroid. If it gets to enter the atmosphere of the Earth, it will start to burn by friction with it (combustion) and it will be called a meteor, while if it hits the surface, it will be called a meteorite.
The kinetics formula that applies to this problem is
1. To find height, we use 1/2mv12−mg∗μ∗h sin θ = mgh where μ is equal to 0.20, v is 11 m/s and <span>θ is 40 degrees. we cancel mass, h is equal to 5.47 meters.
2. The final speed is from 2(ug</span>) * h sin <span>θ </span><span> = vf2
</span>2(0.2*9.8) * <span>sin 40 * 5.47= vf2 ; vf is equal to 3.71 m/s.

The area between the thorajand pelvis in humans constitutes the part of the body
known as the SPINE
Use f = uN to find the coefficient of friction. We know friction (6.0 N) and the normal forces (18 N), so plug them in to the equation which gives us 6 = u18. Solving for u: <span>u = 0.33</span>
