Answer:
Option B = 60,600 mg (correct option)
Explanation:
First of all we will have an idea which numbers are consider as significant.
1 = All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
2= Leading zeros are not consider as a significant figures. e.g. 0.02 in this number only one significant figure present which is 2.
3= Zero between the non zero digits are consider significant like 105 consist of three significant figures.
4= The zeros at the right side e.g 3400 are also significant. There are four significant figures are present.
In given options, Option A 60.6 mg have 3 significant figures.
Option B have 5 significant figures.
Option C have 4 significant figures.
Option D have 3 significant figures.
Thus option b is correct option which have more significant figures.

A volume is measured experimentally as
4.09 mL. What is the percent error, given
that the correct value is 4.13 mL?
Answer in units of %.
Answer:
The answer is 0.97 %Explanation:
The percentage error of a certain measurement can be found by using the formula
[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]
From the question
actual volume = 4.13 mL
error = 4.13 - 4.09 = 0.04
We have
[tex]p(\%) = \frac{0.04}{4.13} \times 100 \\ = 0.968523002...[/tex]
We have the final answer as
0.97 %Hope this helps you

Which of the questions would involve the investigation of kinetic energy?
A. What material makes the strongest boat?
B. How does the color of a boat affect heat absorption?
C. Do boats float higher in salt or fresh water?
D. What is the effect of a boat’s shape on its speed?
Answer:
D. What is the effect of a boat’s shape on its speed?
Explanation:
Kinetic energy can be defined as the energy possessed by an object or body due to its motion. It is the amount of work required to accelerate an object or body with a specific mass from its point of initial rest to a final velocity.
Mathematically, kinetic energy (K.E) is equal to 1/2(mv²).
Hence, the question which would involve the investigation of kinetic energy is "what is the effect of a boat’s shape on its speed?" because speed is directly related to the motion of the boat. Generally, the shape of the hull of a boat has an effect on the speed of the boat.
Answer:
What is the effect of a boat’s shape on its speed?
1.if I drove 40 miles west in 2 hours what is my velocity
2.find the time it takes for a bird that travels 15 miles per hour for 3 hours
1. v= 20 miles/hr
2. d = 45 miles
Further explanationVelocity is a vector that has both magnitude and direction
Velocity is the ratio of distance per time
Can be formulated :
[tex]\tt v=\dfrac{d}{t}[/tex]
v , m/s
d , m
t, s
1. d = 40 miles
t = 2 hr
[tex]\tt v=\dfrac{40~miles}{2~hr}\\\\v=20~miles/hr[/tex]
2. maybe you meant the distance traveled
v = 15 miles/hr
t = 3 hr
[tex]\tt d=v\times t\\\\d=15\times 3\\\\d=45~miles[/tex]

what part of the atom canot have its part acuratly determined ill give brainlest hurry
Answer:
The answer to this question would be electron.
Electron is located on the outer side of the atom and constantly moving in an orbit so its location cannot be accurately determined. The cloud around the center of the atom is drawn to picture the orbit.
Neutron and proton located in the middle of an atom in a part that called nucleus. Nucleus location is kept at the center and it doesn't move.

Which refers to the number of wavelengths that pass a fixed point in a second?
wavelength
O amplitude
frequency
O compression
Please hurry will give brainliest on 10 mins
Answer:
frequency
Explanation:
The number of wavelengths that pass through a fixed point in a second is called the frequency of the wave. It has the unit of Hertz. Hence, option C is correct.
What is frequency ?The term that refers to the number of wavelengths that pass a fixed point in a second is frequency.
Frequency is a fundamental concept in wave motion and is defined as the number of complete cycles of a wave that occur per unit time. For example, the frequency of a sound wave is measured in hertz (Hz) and is equal to the number of sound wave cycles that occur per second.
The higher the frequency of a wave, the more cycles occur in a given period of time. Wavelength, on the other hand, refers to the distance between two adjacent points on a wave that are in phase with each other, such as the distance between two crests or two troughs.
Wavelength and frequency are related, and the frequency of a wave is inversely proportional to its wavelength. As the frequency of a wave increases, its wavelength decreases.
Amplitude refers to the maximum displacement of a wave from its equilibrium position, while compression is a region in a longitudinal wave where the particles are close together. Hence, option C is correct.

B C A
Explanation:
because as you pour the blue stuff in it will straight up go to the bottom (and has less blue coloring) Then it will go to the top (lil more blue coloring) then eventually the whole jar will be blue
hope this helps you out bro
Answer:
The order is B, C, A.
Explanation:
When the liquid is first poured into the container, the entropy is still very high because there is a very large difference in color of the liquid. The more time passes, entropy becomes lower because the blue color liquid disperses through the rest of the container. So the entropy is the highest in B and lowest in A. At A the entropy is as close to 0 as it can be in this situation out of the three parts.
Is acetaminophen conductive in water?
Answer:
Yes, acetaminophen is conductive in water.
Explanation:
Have a nice day!
Acetaminophen is conductive in water and it is electrochemically active. It is used as an antipyretic drug.
What is acetaminophen ?Acetaminophen is an organic compound containing the amine functional group. One of the most popularly prescribed analgesic and antipyretic medications, acetaminophen (AC), is thought to be both effective and safe.
AC is not poisonous or harmful when used rationally, but an overdose or continued use may cause nephrotoxicity and severe hepatotoxicity. As a result, AC monitoring is crucial for drug safety.
Various conductometric measurements reported the fair conductivity shown by acetaminophen in water. The intermolecular interaction of acetaminophen in water make it conductive.
