NASA’s Apollo Mission was the ONLY mission which landed humans on the moon, which it did six times. I’m not very sure about several times, though. Hope this helped!

<span>To find the wavelength of a neutron can be calculated by using the formula
Wavelength=h/m x v
Where h is planck's constant
m=mass of neutron
v= velocity of the particle
By substituting the given values
Wavelength= 6.63 × 10–34 j s / 1.675 × 10–27 kg x 2 m/s^-1
Wavelength of a neutron=1.979 x 10^-7 m</span>
Amagat's law of additive volumes states that we can simply add up the individual volumes of each gas (provided they are at the same temperature and pressure) to get the total volume of the mixture. Conservation of volume is an acceptable assumption for gases (but not always for liquid mixtures). This works for gases since the molecules are very small and only take up a minimal amount of space in a gas.
Couloumb's law : (1/(4*pi*epsilon_nought))*((q_1*q_2)/r^2)
8.99*10^9* ((charge of a proton*charge of an electron)/(6.5*10^10m)^2)
8.99*10^9* ((1.602*10^-19)(|-1.602*10^-19|)/((6.5*10^10)^2)
=5.4608*10^-50
It is Pericarditis I believe.
