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

Describe the three mechanisms of heat flow (conduction, convection, and radiation), and the factors that influence their rates.
Answer:
Just as interesting as the effects of heat transfer on a system are the methods by which it occurs. Whenever there is a temperature difference, heat transfer occurs. It may occur rapidly, as through a cooking pan, or slowly, as through the walls of a picnic ice chest. So many processes involve heat transfer that it is hard to imagine a situation where no heat transfer occurs. Yet every heat transfer takes place by only three methods:
Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.
Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.
Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body.

Conduction:
As you walk barefoot across the living room carpet in a cold house and then step onto the kitchen tile floor, your feet feel colder on the tile. This result is intriguing, since the carpet and tile floor are both at the same temperature. The different sensation is explained by the different rates of heat transfer: The heat loss is faster for skin in contact with the tiles than with the carpet, so the sensation of cold is more intense.
Convection :
In convection, thermal energy is carried by the large-scale flow of matter. It can be divided into two types. In forced convection, the flow is driven by fans, pumps, and the like. A simple example is a fan that blows air past you in hot surroundings and cools you by replacing the air heated by your body with cooler air. A more complicated example is the cooling system of a typical car, in which a pump moves coolant through the radiator and engine to cool the engine and a fan blows air to cool the radiator.
Radiation :
You can feel the heat transfer from the Sun. The space between Earth and the Sun is largely empty, so the Sun warms us without any possibility of heat transfer by convection or conduction. Similarly, you can sometimes tell that the oven is hot without touching its door or looking inside—it may just warm you as you walk by. In these examples, heat is transferred by radiation. That is, the hot body emits electromagnetic waves that are absorbed by the skin. No medium is required for electromagnetic waves to propagate. Different names are used for electromagnetic waves of different wavelengths: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.

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.

Answer:
doppler effect
Explanation:
''The Doppler effect occurs for light as well as sound. For instance, astronomers routinely determine how fast stars and galaxies are moving away from us by measuring the extent to which their light is “stretched” into the lower frequency, red part of the spectrum''

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.
What is the volume of the toy car that has a density of 3 g/mL and a mass of 75 g.
Answer:
The volume of car having density 3 g/mL and mass 75 g is 25 mL.
Explanation:
Given data:
Volume of car = ?
Density of car = 3 g/mL
Mass of car = 75 g
Solution:
The given problem will be solved through density formula.
Density:
Density is equal to the mass of substance divided by its volume.
Formula:
D=m/v
D= density
m=mass
V=volume
Now we will put the values in formula.
3 g/mL = 75 g/ v
v = 75 g/ 3 g/mL
v = 25 mL
The volume of car having density 3 g/mL and mass 75 g is 25 mL.

Explain how metallic bonding supports the properties of metals
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.

When the wedges are removed, predict which way the carts will move. Justify your prediction.
Answer:
I believe the carts will move towards each other, as positive and negative charges attract each other.
Explanation:
It is like a magnet when you put the opposite sides together. (North and South, South and North) or the plus goes to the minus and the minus goes to the plus.
If you take out the far left and right wedges, it may move a little away for a few seconds, but will move back together .
Another hypothesis is that if the sheets are flimsy, the sheets will attract each other, however, the sheets will join together at the top, but the carts will still stay at the same place.
