Answer:
11060M Joules, where M is the mass of the diver in kg
Explanation:
Mass of the skydiver missing, we're assuming it's M.
It's total energy is the sum of the contribution of his kinetic energy (K)- since he's moving at 50 m/s, and it's potential energy (U), since he's subject to earth gravity.
Energy is the sum of the two, so 
Answer:
G.) The number atoms of that element in the molecule
Explanation:
F is incorrect because the coefficient represents the amount of one type of molecule, not the subscript
G is correct because subscripts represent how many atoms of that element are present in that single molecule
H is incorrect because energy is not represented in this simple type of equation
J is incorrect because it doesn't even make sense
Answer:
this measurement if feet is: 2.624672 ft
Explanation:
Notice that 80 cm can be expressed as 0.8 meters, and In order to convert from meters to feet, one needs to multiply the meter measurement times 3.28084. Therefore:
0.80 m can be written in feet as: 0.80 * 3.28084 feet = 2.624672 feet
Non metals produce something called protons they are ions
