Answer:
It will increase to 5ᵒC.
Explanation:
Tom has a meter stick which is marked off in centimeters (cm). he measures a distance three (3)
times and gets measurements of: 11.52m, 11.51m, and 11.51m. a later calibration of the stick
shows it to be actually 1.001m long (1mm too long). tom's friend bill also has a meter
stick but
it's marked off in millimeters (mm). he measures the same distance three times also, and gets:
11.452m, 11.451m, and 11.451m. a later calibration of his stick shows it to be 1.05m long (5 cm
too long)
a.
whose measurements are more precise, tom's or bill's?
b. whose measurements are more accurate?
a. The measurement done by Bill is more precise than Tom. Because all the measurements done by Bill are measured up to mm and which are very close to each other, but for Tom's measurement value measured up to cm.
b. The measurement done by Tom is more accurate than Bill's measurement. Because the actual scale of meter scale is close to 1.001m, which is off by 1mm, but Bill's meter stick is 1.05m, which have errors in centimeters.
What is meter scale?Length is one of the fundamental units in system of measurement. The SI unit of the length is meter. The meter scale is apparatus for measurement of the length of any object. Example: The length of square is 5 meters. Here, 5 is magnitude of the length and meter is the unit of length. 1 meter of meter scale is divided into 100 centimeters. Meter scale is used to measure the Length.
Note: The meter scale reading does not change with the temperature and other physical quantities. The scale used for measurement should not be affected by the physical environment, it should be available easily. Thus, to make any device for measurement of physical quantity above criteria should be kept in mind.

A solution is made by mixing 11.g of water and 72.g of acetic acid hch3co2. calculate the mole fraction of water in this solution. round your answer to 2 significant digits.
The Mole fraction of Water in this solution is 0.34
We know that,
Mole Fraction of Water = No. of moles of Water / Total number of moles of the solution
No. of moles = Mass / Molar mass
Given that,
Mass of Water = 11g
Mass of Acetic acid = 72g
Molar mass of Water = 18.015 g/mol
Molar mass of Acetic acid = 60.052 g/mol
No. of moles of Water= 11 / 18.015= 0.611 moles
No. of moles of Acetic acid = 72 / 60.052= 1.199 moles
Total no. of moles = 0.611+ 1.199 = 1.81 moles
Mole fraction of chloroform = 0.611 / 1.81 = 0.338
In a solution containing at least 2 components, the number of moles of one component divided by total number of moles in that solution is called Mole fraction.

Tides are strongest when the:________
a. sun is setting
b. earth, moon, and sun are in line.
c. body of water is very large.
d. moon and sun are at right angles to the earth.
Tides are strongest when the earth, moon and sun are in line.
What are tidal waves?A tidal wave is a periodically occurring shallow water wave brought on by the ocean's gravitational interactions with the Sun, Moon, and Earth. Despite the fact that tides have nothing to do with tsunamis, the phrase "tidal wave" is frequently used to describe them. A storm surge, storm flood, tidal surge, or storm tide is a tsunami-like occurrence of rising water that frequently occurs along coastlines during low-pressure weather systems like cyclones. It is calculated as the increase in water level over the average tidal level and excludes waves.

The area of an equilaterla triangle is increasing at a rate of 5 m^2/hr. find the rate at witch the height is chganging when the areai is:_________
The rate at which the height is changing is ( 5 / x ) m / hr
We know that,
Area of an equilateral triangle A = [tex]\sqrt{3}[/tex] [tex]x^{2}[/tex] / 4
h = [tex]\sqrt{3}[/tex] x / 2
Where,
x = Side
h = Height
Given that,
dA / dt = 5 [tex]m^{2}[/tex] / hr
h = [tex]\sqrt{3}[/tex] x / 2
Differentiate both sides with respect to t
dh / dt = ( [tex]\sqrt{3}[/tex] / 2 ) ( dx / dt )
dx / dt = ( 2 / [tex]\sqrt{3}[/tex] ) ( dh / dt )
A = [tex]\sqrt{3}[/tex] [tex]x^{2}[/tex] / 4
Differentiate both sides with respect to t
dA / dt = ( [tex]\sqrt{3}[/tex] / 4 ) ( 2x ) ( dx / dt )
5 = ( [tex]\sqrt{3}[/tex] / 4 ) ( 2x ) ( 2 / [tex]\sqrt{3}[/tex] ) ( dh / dt )
dh / dt = ( 5 / x ) m / hr
Rate of change of height is defined as the rate at which height of an object changes with respect to time. It is represented as dh / dt
Therefore, the rate at which the height is changing is ( 5 / x ) m / hr

Unshielded twisted-pair cable capable with a specification of 100 mhz/100 mbps is also called category ________.
Unshielded twisted-pair cable capable with a specification of 100 MHz/100 maps is also called category of switch.
What is Unshielded twisted-pair cable?The unshielded turned pair link is 100-ohm copper link that is constitutive of unshielded curved matches which range somewhere in the range of two to 1,000 and 800. They have no metallic covering on top of the contorted wires. This enjoys the benefit of making the link more modest in distance across. One normal use for protected wound pair links is to involve it in outrageous cold circumstances. Many individuals know that critical exploration is being led in very chilly region of the world. Truth be told, turned pair links have tracked down a great deal of utilizations in the media communications industry prior to getting well known in the PC organizing industry.
