Water is densest at 4°C. What is that temperature on the Kelvin scale?

Answers

Answer : The temperature on the kelvin scale is, 277.15 Kelvin

Explanation :

As we are given the temperature in degree Celsius. Now we have to need to convert the temperature from degree Celsius into kelvin.

Conversion used for the temperature from degree Celsius to Kelvin :

$K=^oC+273.15\n\nK=4^oC+273.15=277.15K$

Therefore, the temperature on the kelvin scale is, 277.15 Kelvin

4 + 273.15 = 277.15K

The world's record in the 100 m dash is 9.69 seconds and in the 100 yard dash is 9.21 seconds. A) find the speed in mi/h of the runner who set the record of 9.69 seconds.
B) find the speed in mi/h of the runner who set the record of 9.21 seconds.

Answers

Speed is equivalent to the distance traveled divided by the time it takes to travel that certain distance.
To solve this problem convert the units first from meter and yards to miles. 100 metes is 0.0621371mi and 100 yards is 0.0568182 yard. 9.69s = 0.002691667 hr and 9.21s = 0.002558333

A.) 23mi/hr
B.) 22.20mi/hr

Answer:

A) The speed of the runner is 23.085 mile/hr.

B) The speed of the runner is 22.209 mile/hr.

Explanation:

$Speed=\frac{\text{Distance covered}}{\text{Time taken}}=(D)/(T)$

A) Distance covered in 9.69 seconds = 100 m

1 mile = 1609.34 m

$100 m =100* (1)/(1609.34) miles=0.062137 miles$

1 hour = 3600 seconds

9.69 s = $9.69* (1)/(3600) hr=0.002691 hr$

Speed of the runner = $(0.062137 mile)/(0.002691 hr)=23.085 mile/hr$

The speed of the runner is 23.085 mile/hr.

B) Distance covered in 9.21 seconds = 100 yards

1 mile = 1760 yards

$100 yards =100* (1)/(1760 ) miles=0.05681 miles$

1 hour = 3600 seconds

9.21 s = $9.21* (1)/(3600) hr=0.0025583 hr$

Speed of the runner = $(0.05681 mile)/(0.0025583 hr)=22.209 miles/hr$

The speed of the runner is 22.209 mile/hr.

As you go down the periodic table, the atomic radius of elements do what?

Answers

Atomic radii increase as you travel down the periodic table, due to increasing number of electron shells.

Increase. This is because more energy levels are available the lower you go in the table.

The radius of an atom of gold (Au) is about 1.35 Å.How many gold atoms would have to be lined up to span 9.5 mm ?

Answers

Answer : The number of gold atoms will be, $3.52* 10^7$

Explanation :

First we have to determine the diameter of an atom of gold.

$Diameter=2* Radius$

Given :

Radius of an atom of gold = $1.35\AA$

$Diameter=2* 1.35\AA=2.7\AA$

Conversion used : $(1\AA=10^(-7)mm)$

$Diameter=2.7\AA=2.7* 10^(-7)mm$

Now we have to calculate the number of gold atoms.

$\text{Number of gold atoms}=\frac{\text{Span length}}{\text{Diameter of an atom of gold}}$

$\text{Number of gold atoms}=(9.5mm)/(2.7* 10^(-7)mm)=3.52* 10^7$

Therefore, the number of gold atoms will be $3.52* 10^7$

Two radius of an atom is equal to the diameter. Adding up all the diameter of the atoms, it should be equal to 9.5 mm. Therefore, we simply convert the units to the same units then divide 1.35 A to 9.5 mm. We calculate as follows:

no. of atoms = 0.0095 m / 1.35x10^-9 m = 7037037 atoms

Hope this answers the question. Have a nice day.

What is measurement?

Distance is a physical quantity which is measured in meter. If a man travel then it is measured in meters that defines that how much he travel from one point to another point for all these type of things we use to measure distance.

Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance.

Kilometer is also a physical quantity which use to measure the distance 1 kilometer is equal to 1000 mtr and 1 kilometer is equal to 100000 centimeter.

For above conclusion, we easily states that the kilometer is large quantity to measure distance while centimeter is smaller quantity to measure distance. Centimeter is also a physical quantity which is use to measure distance. 1 centimeter is equal to 0.01 meter and 1 centimeter is equal to 0.00001 kilometer.

Therefore, a) 67000 b) 0.20 c) 52.8010 d) 3.17000 are the answers respectively.
