It is 3.2 because you add 2.3 and 4.1 then divide your answer by 2.

A barge floating in fresh water (rho = 1000 kg/m^3) is shaped like a hollow rectangular prism with base area A = 550 m^2 and hei

patriot [66]

Answer:

Explanation:

A )

When empty , H₀ length of barge is inside water .

volume of barge inside water = A x H₀

Weight of displaced water = AH₀ x ρ x g

Buoyant force = weight of displaced water = AH₀ ρg

B)

It should balance the weight of barge

Weight = buoyant force

Weight = AH₀ ρg

mass of barge = weight / g

weight / g = AH₀ ρ

= 550 x .55 x 1000

= 302500 kg

by doing a nuclear diffraction experiment, you measure the de broglie wavelength of a proton to be 8.29 fm. (a) what is the spee

Irina18 [472]

By the de Broglie wavelength equation, the speed of proton is <u>0.47 × </u> $10^{8}$ <u> m/s</u>.

λ = h / mv

λ = wavelength, given = 8.29 fm

h = plank's constant, given = 6.626 × $10^{-34}$

m = mass, given = 1.672 × $10^{-27}$ kg

v = velocity

Now, v = h / mλ

Put the values in formula, v = h / mλ

v = 0.47 × $10^{8}$ m/s

Therefore, the speed of proton is<u> 0.47 × </u> $10^{8}$ <u> m/s</u>.
