Calculate the wavelength of light with an energy of 3.60x10^-19 J *

Explanation:

from E = mc^2 and de Broglie wavelength=h/mc

combine the eqns with respect to m(considering the body is moving with the speed of light(c))

then

E= hc/de Broglie wavelength

since, c= 3× 10^ 8

h= 6.626 × 10^ -34 and E is given, substitute the values.

sorry I don't have my calculator.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
