It would have 20 protons, 20 neutrons, and 20 electrons. Protons and electrons are USUALLY (I say usually because of the different types of atoms) the same as the atomic number. To find neutrons you take the atomic mass minus the atomic number. 40-20=20
Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.
<span>Gravity assists the marble, leading to conservation of energy. The
stored energy is release as momentum, the output of energy is constant.</span>
Answer:
Location A
Explanation:
Coastal areas have milder temperatures since they are close to water and water retains heat better than land (it's harder to warm it up and harder to cool it down). Due to this property of water, the location with the least temperature fluctuation would be the answer. Location A has the smallest range between the highest and lowest annual temperatures, making A the best answer choice. I hope I helped and that it's not too late for you.
Answer:
The answer is letter D
Explanation:
<em>The set point is the weight range in which your body is programmed to function optimally. Set point theory affirms that an indivual's body will fight to mantain that weight range. Evebody is biologically and genetically determined to weigh within a certain weight range. Set points will vary for each individual person. </em>
<em>Scientists estimate that the average person has a set point range about ten to twenty pound rage at which your body will be comfortable and not resist attempts to change.</em>
Nicotinamide adenine dinucleotide (NAD+) and flavin adenine dinucleotide (FAD+) are two cofactors that are involved in cellular respiration. They are responsible for accepting "high energy" electrons and carrying them ultimately to the electron transport chain where they are used to synthesize ATP molecules.
