9x102: 3x1012
Answer:
3 × 10¯¹⁰
Explanation:
9×10² ÷ 3×10¹²
The above expression can be simplified as follow:
9×10² ÷ 3×10¹²
Recall:
9 = 3²
9×10² ÷ 3×10¹² = 3²×10² ÷ 3×10¹²
Recall:
a^m ÷ a^n = a^(m – n)
3²×10² ÷ 3×10¹² = 3^(2 – 1) × 10^(2 – 12)
= 3¹ × 10¯¹⁰
Recall:
a¹ = a
3¹ × 10¯¹⁰ = 3 × 10¯¹⁰
what does it mean to be in the path of totality science
Answer:
The track of the Moon's shadow across Earth's surface is called the Path of Totality. This path is typically 16,000 kilometers (about 10,000 miles) long but only 160 kilometers (100 miles) or so wide. In order to see the Sun totally eclipsed by the Moon you must be in the path of totality.

What is the total number of sp2-hybridized carbon atoms present in the fluorophore used in the experiments
Answer:
9
Explanation:
The structure of fluorophore used in the experiments has been drawn in the attachment. And from the drawing counting we can say that there are 9 sp2-hybridized carbon atoms present. Fiuorophores are a fluorescent chemical compound that can re-emit light upon light excitation. Normally used to produce absorbance and emission spectra.
Are spirit filled thermometers safer than mercury filled ones?
Answer:
Yes they are safer.
Explanation:
As far as I know Spirit filled thermometers contain alcohol which is much less toxic than mercury. Mercury is a heavy metal and is therefore fairly toxic similarly to lead.
I hope this helps let me know if anything is unclear.
Your question has been heard loud and clear.
Yes , spirit filled thermometers are safer than mercury ones , actually they are made to be safer than the mercury.
In a spirit filled thermometer , it is precise and also there really is no risk of the stuff (usually alcohol or organic liquid) exploding if the thermometer glass breaks unlike the mercury thermometer , where if the glass breaks , there is a high risk of the mercury ball intoxicating the air and endangering lives.

Which of the following is a chemical property? Select one: a. The air pressure at sea level is higher than that in Denver, Colorado. b. Water boils at 100°C. c. The rusting of the joints of a metal children’s swing set.
Answer:
c. The rusting of the joints of a metal children’s swing set.
Explanation:
By definition, chemical property describes the ability of a substance to undergo a specific chemical change.
In the definition above, the key words are; "Chemical change".
Generally, chemical changes are irreversible. This means we just have t observe the options and pick the one that contains an irreversible change.
Upon doing ths, the correct option is;
c. The rusting of the joints of a metal children’s swing set.
This is because rusting is a chemical change and is irreversible.

.239cal=J joules. How many joules J are in 450cal?
Answer:
1.89
Explanation:
238cal = J joules
450cal = xJ joules
[tex] \frac{450}{238} = \frac{xj}{j} [/tex]
1.89 = x
450cal = 1.89J joules

One gallon is equal to 16 cups. One cup is equal to 8 ounces. Assume you have 10.24 ounces of milk. Convert this value to gallons. show work
Answer:
There 0.08 gallon in 10.24 ounces of milk.
Explanation:
It is given that,
1 gallon = 16 cups ....(1)
1 cup = 8 ounces ....(2)
We need to convert 10.24 ounces of milk to gallons.
From equation (2)
1 ounce = 1/8 cup
10.24 ounce = [tex]\dfrac{1}{8}\times 10.24=1.28\ \text{cup}[/tex]
From equation (1),
1 cup = 1/16 gallon
1.28 cup = [tex]\dfrac{1}{16}\times 1.28=0.08\ \text{gallon}[/tex]
So, there 0.08 gallon in 10.24 ounces of milk.

6.02 x 1023
Significant figures
Answer:
It depends on the number of significant figures you are changing to
Explanation:
6.02×1023=6158.46
1 sig fig = 6000
2 sig fig = 6200
3 sig fig = 6160
4 sig fig = 6158
5 sig fig = 6158.5
6 sig fig = 6158.46
When solving significant figures you have to consider the number after each number like in the case of changing to two sig fig the number following one is five and when the number is up to or greater than five you add a value of one to the number before it. But in a case where the number is less than five you just leave it like that like in the case of changing to one sig fig

Water flows over Niagara Falls at the average rate of 2,400,000 kg/s, and the average height of the falls is about 50 m. Knowing that the graviatational potential energy of falling water per second = mass (kg) x height (m) x gravity (9.8 m/s2), what is the power of Niagara Falls? How many 15 W LED light bulbs could it power?
Answer:
1) The power of Niagara Falls is 1.176 × 10⁹ W
2) The number of 15 W LED light bulbs it could power is 78.4 × 10⁶ light bulbs
Explanation:
1) The Niagara falls water mass flow rate = 2,400,000 kg/s
The height of the fall = 50 meters
The gravitational potential energy = Mass (kg) × height (m) × gravity (9.8 m/s²)
The power = The energy converted per second = Mass flow rate (kg/s) × height (m) × gravity (9.8 m/s²)
Therefore;
The power of Niagara Falls= 2,400,000 kg/s × 50 m ×9.8 m/s²= 1.176 × 10⁹ W
The power of Niagara Falls = 1.176 × 10⁹ W
2) The number, n, of 15 W LED light bulbs it could power is given by the relation;
n × 15 W = 1.176 × 10⁹ W
∴ n = 1.176 × 10⁹ W/(15 W) = 78.4 × 10⁶ light bulbs
The number of 15 W LED light bulbs it could power = 78.4 × 10⁶ light bulbs.

Which statement best describes a physical change? 1. Changes can occur to certain chemical properties of the substance, but the overall shape of the substance will remain the same. 2. Changes can occur to certain physical properties of the substance, but the overall shape of the substance will remain the same. 3. Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same. 4. Changes can occur to chemical properties of a substance, but the chemical composition of the substance remains the same.
3. Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same.
A physical changes the physical properties of a substance, but not the chemical composition. If it changed the chemical composition, it would be a chemical change. Typically a physical change can be reversible. Therefore, some typical examples of a physical change are:
- melting
- transition to a gas
- textural change
- change in shape
- change in size
Answer:
Its 3. Changes can occur to physical properties of a substance, but the chemical composition of the substance remains the same.
