19. 160 g of molten silver at its melting point, 960°C, is allowed to solidify at the same temperature and gives out 16 800 J of heat. (a) Calculate the specific latent heat of silver?

And

If the mean specific heat is 230j/k. How much additional heat does it give out in cooling to -40C?

come closer and become far apart and become steam/gas

find the sum of the two horizontal vectors and the sum of the two vertical vectors

where is the

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
