Your skin is your largest organ and a crucial part of several bodily functions. Not only is it the flexible, self-healing barrier that supports the immune system, but it's also part of the integumentary system, the network of dead epidermal cells --hair, fingernails and toenails -- that helps slough off cellular waste material. Sweat glands in the skin also play active roles in the excretory system, or the organs and glands that flush out toxins and excess minerals from the body.
Dead skin cells are a form of bodily waste that facilitates the growth of new epidermal cells. Every minute, you lose 30,000 to 40,000 dead skin cells, all of which are replaced immediately by fresh skin tissue [source: KidsHealth.org]. The body does an excellent job of sloughing off skin cells through normal activity, but regular bathing is definitely a plus.
Answer:
The answer is 1722 e⁻
Explanation:
Let's make a rule of three:
9.708×10⁻³¹ kg is the mass of 1 e⁻
1.672 ×10⁻²⁷ kg (which is 1 p⁺), how many e⁻ does it contain.?
1.672 ×10⁻²⁷ kg / 9.708×10⁻³¹ kg
The answer is 1722 e⁻
Answer:
Explanation:
The given number is 6.02 × 10⁹. It is written is scientific notation.
As you see it has two parts:
- The first part are the digits with the decimal point after the first digit. This part is called mantissa. The mantissa can only have one digit, between 1 and 9, before the decimal point.
- The second part is a power of 10. The exponent can be either positive or negative.
If the exponent is negative means that the decimal point must be moved to the left and if the exponent is positive means that the decimal point must be moved to the right.
In the number 6.02 × 10⁹ the exponent is 9, so you must move the decimal point 9 places to the right:
- 6.02 × 10⁹ = 6.02 × 1,000,000,000 - 6,020,000,000,
