c. 24 meters

d. 24 grams

What is scientific notation?

Scientific notation is a way of representing a quantity as a number having significant digits that are necessary for a specified degree and multiplied by ten to the power.

The general form of scientific notation can be written as [tex]N \times 10^{a}[/tex].

A significant digit is that digit in a number which adds to its precision. A significant includes all nonzero numbers, zeros between significant digits, and zeros represent to be significant while leading and trailing zeros are not significant digits as they exist only to represent the scale of number.

Given, using the scientific notation method we can write the scientific notation of the distance of 671,030 km.

The number 671,030 km can also be written as 6.71030 ×10⁵ km.

Therefore, the correct way to write this distance in the scientific notation of  671,030 km is 6.71030 ×10⁵ km.

Which measurement has 2 significant figures? *
0.00601 m
O
0.00600 m
0.00066 m
0.006060 m
0.006006 m

Answers

Answer:

[tex]0.00066[/tex]

Explanation:

Any number is significant if;

» It is before the decimal point. i.e; 1.000 [1 is a significant figure] and all other values will be significant. Hence the value has 4 signigicant figures.

» It is non-zero value, and when it is after a decimal point. i.e; 0.1, 0.01, 0.0001 [1 is the significant figure]. Hence each value has one significant figures.

» It is after any non-zero value, that comes after a decimal place. i.e; 0.00100 [the last two zeros are significant]. Hence the value has three significant figures.

Summary :

• 1.00 » three significant figures. ( 1 only )

• 0.01 » one significant figure. ( 1 only )

• 0.010 » two significant figures. ( 1 and last zero )

• 0.01006 » four significant figures (1, last two zeros, and 6)

• 0.00066 » two significant figures ( 6 and 6 )

problems.

Answers

By understanding conversion factors and how they are related to each other we can use dimensional analysis to solve  problems.

Dimensional Analysis is a step by step approach to solving problems in Physics, Chemistry , and Mathematics. It involves having a clear knowledge and understanding to be able to convert a given unit to another in the same dimension using  conversion factors and knowing how they are related to each other.

For instance, In Chemistry, we want to Convert 120mL to L.(note that ml stands for millilitres and ;L stands for litres)

Or first approach will be to write out the conversion factor related to our problem which is

1000ml =1L

such that 120ml = (we cross multiply))

giving us  120ml x 1L/1000ml =0.12L

This same process is applied to convert any type of dimensional analysis problems be it physics or mathematics.

Sofia is trying to find the density of a 25.0 g irregularly shaped solid. She filled a graduated cylinder with 25.0 mL of water. After adding the solid the water rises to 56.5 mL. What is the density of the solid? Does this solid float or sink in water

Answers

The volume of the solid is
56.5 ml - 25 ml = 31.5 ml
The mass of the solid = 25g
So the density is Mass/ Volume
25/ 31.5 = 0.79 g/ml

Since the solid has a lower density (0.79 g/ml) than the density of water (1g/ml) it will float on water

Answer:  Density:  0.794 g/ml.  It would float.

Explanation:  The mass of 25.0 grams displaces (56.5 - 25.0) = 31.5 ml of water, it's volume (when submerged).  Density is mass per unit volume:

25.0 grams/31.5 ml = 0.794 g/ml

Water's density is 1 g/ml, so this obect would float.  (Don't ask me why it displaced 31.5 ml.  It won't unless it is pushed down, then the volume of the finger needs to be determined and subtracted from the calculated volume.

3. If you started with a sample of 600 radioactive nuclei, how many would
remain undecayed after three half-lives?

Answers

Answer:

[tex]\boxed {\boxed {\sf 75 \ radioactive \ nuclei}}[/tex]

Explanation:

Radioactive decay occurs in unstable atom nuclei. The ratio of protons to neutrons is off, causing the instability. The nuclei release particles and radiation to change into different atoms.

The half-life is the time it takes for half of the nuclei to decay. We don't know the half-life of the sample, but we know it undergoes 3 half-lives. Therefore, the number of radioactive nuclei halves every time the sample undergoes a half-life.

We can divide the number of nuclei in half 3 times to find the amount left after 3 half-lives.

1st half-life: 600/2 = 300 2nd half-life: 300/2 = 150 3rd half-life: 150/2= 75

After 3 half-lives, 75 radioactive nuclei remain undecayed.
