Explanation:
Close proximity to the equator leads to very mild winters. Hotter climate year round and snow being extremely rare
The discovery of Uranus, Neptune, most asteroids, the moons of
any planet other than Earth, Pluto, and all the other dwarf planets,
required the invention and use of telescopes. Those objects are all
too dim to be seen with a bare naked human eye.
Saturn is bright and plainly visible with your eyes, if you know when
and where to look, and what you're looking at.
The particles that are usually in a much higher energy usually comes from the magnetic field of the Earth in which it is trapped consisting the Van Allen radiation belts. In addition to that, these radiation belts are somewhat essential because it protects satellites orbiting the Earth from the Sun's high energy radiation.
The height of stairs a 60 kg student would have to run in order to burn off 1 Calorie of food energy will be 7.1 meters.
<h3>What is potential energy?</h3>
The potential energy is due to the virtue of the position and the height. The unit for the potential energy is the joule.
Given data;
Mass of student,m = 60 kg
Energy,E = 4190 J
Height of stairs,h=?
The potential energy is mainly dependent upon the height of the object. The potential energy is found as;
Potential energy = mgh
E=mgh
h=E/mg
h= 4190 J / (60 kg× 9.81 m/s²)
h = 7.1 metre
Hence the height of the stairs will be 7.1 meters.
