Answer:
The box is moved at constant speed, then the change in kinetic energy is zero.
Explanation:
Let suppose that box moves at constant speed, meaning that its kinetic energy (
), measured in joules, is expressed by the following equation:
(1)
Where:
- Mass, measured in kilograms.
- Speed, measured in meters per second.
If the box moves at constant speed, then we notice that
, therefore,
. In a nutshell, if the box is moved at constant speed, then the change in kinetic energy is zero.
The date in which the Antarctic Circle has 24 hours of daylight on December 21st every year. When energy is transferred to air the particles of air become more excited and move around faster.
Answer: Neurotransmitters are being produced by neuron and stored in vesicles.
Explanation:
Neurotransmitters are secreted into the synaptic gap by exocytosis process, where the vesicles membranes fuse with the presynaptic button. The synaptic gap is usually in the order of 0.02 micron.
Several neurotransmitters include Acetylcholine, Dopamine, GABA (gamma-aminobutyric acid), Glutamate, Norepinephrine, and Serotonin.
Nitrogen
Explanation:
Adding one proton to a carbon atom makes Nitrogen.
A quick introspection on atoms:
- An atom is made up of three fundamental particles.
- They are protons, neutrons and electrons.
- The protons are positively charged and the neutrons do not carry any charges.
- Electrons are negatively charged.
The difference between an atom and another is the number of protons in them. This is the atomic number.
The periodic table of element is a list of elements arranged based on the number of protons they have. Every element on the table has unique number of protons which makes it differ from another.
- Atoms do not readily lose their protons because they are held by nuclear forces in the nucleus of an atom.
When an element gains a proton, it becomes another element.
Carbon has proton number of 6
If a proton is added to it, it becomes 7
This is the proton or atomic number of nitrogen.

The chemical formula is C6H12O6 .
This is one molecule of Glucose ... the simple sugar that plants and algae make with photosynthesis, and the 'blood sugar' in human beings like you and me.
The formula tells us that each molecule is made of 6 Carbon atoms, 12 Hydrogen atoms, and 6 Oxygen atoms.
