The cat's kinetic energy is
(1/2) x (the cat's mass in kg) x (25 m²/sec²).
The unit is [joules] .
<span>NaCH is not an element, it is a compound. An element can be found and identified on the periodic table to elements. A compound is a combination of two of more elements. NaCH is composed of three elements: Na (sodium), C (carbon) and H (hydrogen), making it a compound.</span>
The atomic number gives you the number of protons element x has. Since the mass of protons and neutrons are almost similar(around 1 amu), the mass number can be thought of as the sum of protons and neutrons. so if element x whose atomic number is 40 has a mass number of 82, then we know that 42 of those must be neutrons.
The force of gravity will change the satellites direction, and therefore its velocity. To complete the sentence "<span>The force of gravity is responsible for continuously changing the velocity of a satellite." Thank you for posting your question here at brainly. I hope it helps. </span>
