Answer:
C. 500 watts
Explanation:
power is defined as the rate of work done
When a force causes a object to move, work is being done on the object by the force.

<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.
Answer:
The atomic mass of an element is the average mass of the atoms of an element, according to google. Sum of protons and neutrons in nucleus is the mass number and multiply by 1 amu gives you the mass of the atom
Answer:
12750m/s
Explanation:
V=lf
Where l is wavelength sorry can't draw it
So v=8500*1.5=12750m/s
1. Momentum is the product of mass and velocity:
(4 kg)·(8 m/s) = 32 kg·m/s
(Note: the units of kg·m/s tell you this.)
2. Momentum is the product of mass and velocity, so two objects with different masses can have the same momentum if ...
<em>the object with the smaller mass has a greater velocity</em>.
