The answer to this question would be:
<span>2. The exponents need to be the same so the leading numbers can be added or subtracted.
3. The result has the same number of decimal places as the least precise number.
</span>The exponent is the 10^x that used in scientific notation. .When adding 12.3* 10^5 with 34.56 * 10^4, you need to make the exponent same first. In this case, it would become 12.3* 10^5 + 3.456 * 10^5= 15.756* 10^5
The decimal place could be rounded up to the least precise number. I'm not sure with the significant figures but it seems to use the biggest one.
Answer:
Interphase: the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
Mitosis: Mitosis is a process where a single cell divides into two identical daughter cells (cell division). The major purpose of mitosis is for growth and to replace worn out cells.
Cytokinesis: Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. ... Mitosis and each of the two meiotic divisions result in two separate nuclei contained within a single cell.
Explanation:
I learned about this and it was pretty confusing. But once you start learning this more, you'll definitely get it! :D
Answer:
The options are not given, here are the options.
metal
a. Metal
b. a metalloid
c. a non-metal
d. a gas
The correct option is C.
Non metal
Explanation:
Henry should classify it as non metals because non metals are substances or elements that are poor conductors of heat and electricity they break easily I .e meaning they lack the ducibility of metals, meaning they cannot be stretched, they are brittle, they are not shiny and does not reflect light, they have high electronegativities that is they have atoms that can hold electrons to what they have.
Answer: 5m
Explanation:
Given that:
Wavelength (λ)= ?
Frequency of wave (F) = 60MHz
[If 1 MHz = 1,000,000 Hz
60MHz = 60 x 1,000,000 = 6 x 10^7Hz]
Speed of wave (V) = 3 x 10^8 m/s
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.
So, apply the formula V = F λ
Make λ the subject formula
λ = V/ F
λ = 3 x 10^8 m/s / 6 x 10^7Hz
λ = 5m
Thus, the wavelength of an electromagnetic wave is 5 metres.
