First, we need to find the amount of winks in an hour, to simplify it so we can answer easier. Since there are 60 minutes in an hour, we can multiply 5 by 60 to find the number of winks in an hour.
5*60=300
Now multiply 300 by 8.
300*8=2,400
She winks exactly 2,400 times per day.
Hope this helps!
Actually, the
uncertainty point is when we have to estimate one place smaller than what the
graduated cylinder can accurately read. So in this case, the smallest that we
can accurately read is given by the minor marks of 0.2 mL. So if it is in
between two minor marks we can only estimate the number, therefore the
uncertainty is +/- 0.1ml.
Answer : There are basically three subatomic particles that exists; namely proton, neutron and electron.
Please refer the attached chart for the complete comparison.
- Protons are observed to be found in the nucleus of the atom. Which appears at the tiny, dense region at the center of the atom. They have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu).
- Neutrons exists in atoms of all elements they have neutrons located in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons do not have any charge they are found to be electrically neutral. The mass of a neutron is slightly greater than the mass of a proton, which is 1 atomic mass unit (amu) .
- Electron are fundamental particles which does not consist of smaller particles. They are a type of fundamental particles called leptons. All leptons have an electric charge of −1 or 0 . Electrons are observed to be extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1 , which is equal but opposite to the charge of a proton, which is +1 . All atoms have the same number of electrons as protons, so the positive and negative charges "cancel out", making atoms electrically neutral.
Answer:
synthesis
Explanation:
I believe answer is d a synthesis reaction
Hello Mate!Well, there are
many definitions and descriptions of isolated systems, and
here are some of them:
1.
It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.
2.
It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.
