Answer:

Hi there!

Your answer is:

In a solar eclipse, we see two types of shadows. One is the "umbra" or the darkest shadow caused by the sun. It's located in the center.

The "penumbra" in a solar eclipse is the shadow that's lighter and located on the sides of the earth. Think about it like this:

The sun and earth are in line. The darkest shadow will continue in that line. That is the umbra. The penumbra continues directly on the outside of the umbra. It's lighter that the other shadow!

A penumbra solar eclipse is when the sun, moon, and earth DONT align properly. This causes a partial eclipse, not a full eclipse. A penumbra solar eclipse is a Partial solar eclipse.

Hope this helps! To be clear, none of this is copied. This is based off of my previous knowledge on the subject and interest in phenomena such as these!

A football is inflated to 12psi at 20°C What is the new pressure in the football

Radda [10]

Answer: The new pressure is 3 psi.

Explanation:

Given: $P_{1}$ = 12 psi, $T_{1} = 20^{o}C$

$P_{2}$ = ?, $T_{2} = 5^{o}C$

Formula used is as follows.

$\frac{P_{1}}{T_{1}} = \frac{P_{2}}{T_{2}}\\\frac{12 psi}{20^{o}C} = \frac{P_{2}}{5^{o}C}\\P_{2} = \frac{12 psi \times 5^{o}C}{20^{o}C}\\= 3 psi$

Thus, we can conclude that the new pressure is 3 psi.

Reil [10]

The heat transfer formula is;
Q = m * c * Δ T >>>> (1)
where, Q is the heat transfer
m = mass (gram)
c = the specific heat capacity (J/g)
Δ T = change in temperature
∵ we have one mole of Ethanol
∴ the weight of ethanol equals its molecular weight = (2*12)+(6*1)+(16) = 46 g
we will assume that the specific heat capacity of ethanol is 2.46 J/g (from google)
ΔT = 25 - 320 = - 295 C
By substitution in (1)
∴ Q = 2.46 * 46 * (-295) = - 33382.2 J

What enables Dna to have so many variations with only 4 chemicals?

elena-s [515]

There are many combinations because it is not all about the number of chemicals, but also about the size of the strand. The longer the strand the more combinations there are and more variations and various lengths provide various results.
