Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.10938356 × 10 −31 kg, which is only 1/1,836 the mass of a proton.
Scientists often work on projects for a long time and fail to see sources of error in their research. Which process allows an outside expert to look at the scientist's project and point to sources of error? direct funding peer review conclusive research data collection
Answer:
The correct approach is Option B (Peer Review).
Explanation:
Rather made reference to someone as a scientific peer-review, it encourages the specialist who has not been essential to the study team to analyze the study objectively and pointed out everyone's mistakes. It serves as major self-regulation for scholars and aims to make the publishing process somewhat credible. Hence, the solution to this issue is Peer Examination.Funding organizations rarely have the capabilities to recognize out mistakes, whereas definitive analysis is a method of study that helps to make a definitive statement. The gathering of data is simply a process of scientific study.Other approaches do not apply to the example mentioned. Although the one mentioned is right.

The skydiver will soon open her parachute. How will her velocity change when
the parachute first opens?
Answer:
How will her velocity change when does parachute first open?
The skydiver's weight is balanced by the air resistance. There is no resultant force and the skydiver reaches terminal velocity. When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.
When a skydiver opens their parachute, they accelerate upwards. This is not the same as saying the move upwards. Acceleration is a change in velocity. They keep feeling an upward force (while moving downward) that slows them until they get to a new terminal velocity.
What force changes when a parachute opens?
An open parachute increases the cross-sectional area of the falling skydiver and thus increases the amount of air resistance which he encounters (as observed in the animation below). Once the parachute is opened, the air resistance overwhelms the downward force of gravity.
What happens if you open the parachute too early?
You are likely to drift off the drop zone. The winds can be pretty heavy at high altitudes, and unless you steer continuously they may blow you off-course. Needless to say, the refrigeration effect of the wind and slipstream will make you feel even colder than the mere altitude. Your landing is likely to be rough.

Which ion is found in all acids
An acid is a chemical that, when added to water, releases hydrogen (H+) ions. The ion is found in all acids is H⁺ ion. Therefore, option B is correct.
What is an acid ?A Brnsted-Lowry acid or Lewis acid is a molecule or ion that has the ability to donate a proton or establish a covalent bond with an electron pair.
An acid is a chemical that, when added to water, releases hydrogen (H+) ions. A hydrogen ion is made up solely of a proton. The formulations for many acids may all be found to contain at least one H, such as hydrochloric acid.
The word "acid," which refers to the sour flavor and pungent odor of numerous acids, derives from the Latin word acidus, which meaning "sour." Examples: Because acetic acid and water are diluted, vinegar has a sour flavor.
Thus, option B is correct.

The molecular geometry of molecules is given serially as, tetrahedral,trigonal,tetrahedral,tetrahedral,linear,linear.
What is molecular geometry?Molecular geometry can be defined as a three -dimensional arrangement of atoms which constitute the molecule.It includes parameters like bond length,bond angle and torsional angles.
It influences many properties of molecules like reactivity,polarity color,magnetism .The molecular geometry can be determined by various spectroscopic methods and diffraction methods , some of which are infrared,microwave and Raman spectroscopy.
They provide information about geometry by taking into considerations the vibrational and rotational absorbance of a substance.Neutron and electron diffraction techniques provide information about the distance between nuclei and electron density.

to what direction does the rope move?
Answer:
This question appears incomplete
Explanation:
However, the direction in which the tension acting on the rope is directed is the direction the rope will move. Hence, when a rope is attached to an object, the rope will only "realistically" move in the opposite direction because the rope cannot push an object but can only pull an object, hence can only move in the direction away from the object.
NOTE: Tension can be defined as the pulling force of an object through the use of a string, chain or anything with a potential to stretch fully.

Answer:
Explanation: Because electrons are delocalized around positively charged nuclei, metallic bonding explains many properties of metals. ... Further, because the electrons are free to move away from each other, working a metal doesn't force together like-charged ions, which could fracture a crystal through the strong repulsion.
The mass of an oxygen–18 atom is 18.0042 amu. Compute the calculated mass.
Answer:
The calculated mass of one atom of oxygen-18 is approximately 2.99×10⁻²³ grams
Explanation:
The given mass of an oxygen-18 atom = 18.0042 amu
The definition of the atomic mass unit is the mass equivalent to the mass of one twelfth the atomic mass of one atom of carbon-12. The atomic mass unit is used to express the mass of an isotope of an element
1 amu = 1.66 × 10⁻²⁴ grams
Therefore;
18.0042 amu = 18.0042 × 1.66 × 10⁻²⁴ grams ≈ 2.99×10⁻²³ grams
The calculated mass of one atom of oxygen-18 ≈ 2.99×10⁻²³ grams
The atomic mass unit can be taken as the mass in grams of one mole of the substance
Therefore, the mass of one mole of the oxygen 18 atom = 18.0042 g
