X/7 = -3 I GOT X=-21 AM I WRITE?

-1 3/4 = p - 1/2 HOW DO I FIGURE THIS OUT

How do i find the input and out put of these numbers input output 25 15 30

How do i find the input and out put of these numbers input output 25 15 30 18 35 21 40 24

Now which of these lines are functions?x=3 y=2 y=2x+5

what is genetic engineering?

give one word/term for each of the following descriptions. 1.A substance that donates electrons in chemical reaction. 2.The formula showing the simplest whole number ratio in which the atoms combine to form a compound.

one word/term. 1.3.The minimum amount of energy required to start a reaction. 1.4.The distance between the centre of a lens and its focal point. 1.5. The type of image formed on a screen when light rays converge.

add 3y-5 to y+16

IS THE PROBLEM 25/4 = Y?

do not understand fallacies

can you say but, because together in the samesentence

Thanks a lot I figured it out yesterday by byself.. Thanks a bunch anyways

apply synonym write a different sentence.use a synonym we had a nice time at the picnic.

According to Miller Index we express the vector as a set of whole numbers, so I multiply through by 3. So, I've tried the crystallographic direction of the red vector as(10-3), but it's still wrong...

manfred, your answer is WRONG

I put the answer of ongrwa and it's WRONG

as bonjo said, let's try to do together - rearrange the equation to make BE(N-N) the subject. BE(NCl) - 96.3[X(N)-X(Cl)]^2 = sqrt[BE(N-N) x BE (Cl-Cl)] BE(NCl) - 96.3[X(N)-X(Cl)]^2 = sqrt[BE(N-N) x BE (Cl-Cl)] (BE(NCl) - 96.3[X(N)-X(Cl)]^2) / sqrt [BE (Cl...

the velocity of the electron is sqrt(2E/m) where E is the bond energy for NN and m is the mass of electron. So, v = sqrt (2 x 36.49 / 0.000548597 amu) v = 72.98/0.000548597 v= 133030.25

now, we use the de Broglie equation to find the wavelength. Broglie equation: w = h / m v, where w = wavelength; h = Planck's constant in J/s; m = mass in kg; v = speed in m/s.

w = what we want to know h = 6.63 x 10^-34 J s m = 9.1 x 10^-31 kg (mass of an electron?) v = I think that I calculete not im m/s

People, I don't know if I'm in the right way... Could someone HELP too??
