goldfiish [28.3K]3 years ago
3 0

Answer:

43.28\frac{lbf}{in^3}=43.28\times 27460.68\frac{kg}{m^3}=1188498.44\frac{kg}{m^3}

Explanation:

Here the given values corresponds to the density of a substance

The density of a substance in standard SI unit is given as Kg/m³.

Given value = 43.28lbf/in³

also

we know,

1 lbf = 0.45kg

1in = 0.0254 m

thus,

\frac{1lbf}{1in^3}=\frac{0.45kg}{0.0254^3m^3}=27460.68\frac{kg}{m^3}

therefore,

43.28\frac{lbf}{in^3}=43.28\times 27460.68\frac{kg}{m^3}=1188498.44\frac{kg}{m^3}

A charged particle is observed traveling in a circular path in a uniform magnetic field. If the particle had been traveling four
8090 [49]

Answer:

The new radius of the trajectory of the particle is four times the previous radius

Explanation:

In order to know what is the radius of the trajectory of the charged particle, if its speed is four times as fast, you take into account the following formula, which describes the radius of a charged particle in a magnetic field:

r=\frac{mv}{qB}          (1)

If the speed of the particle is for time as fast, that is, v' = 4v, you obtain, in the equation (1):

r'=\frac{mv'}{qB}=\frac{m(4v)}{qB}=4\frac{mv}{qB}=4r

The new radius of the trajectory of the particle is four times the previous radius

The energy levels the electron can occupy in the Be3+ ion can be calculated using the energy level equation. Calculate the frequ
hram777 [196]

Answer:

1.32×10^16 hz

Explanation:using Rydberg equation:

1/λ = RH •Z^2[ (1/n1) - (1/n2) ]

RH = Rydberg constant = 1.097 x 10^7 m-1)

n1 and n2 = energy levels (n2 >n1)

Z = atomic number = 4

Substitute

1/λ = 1.097×10^7 • 4^2[ (1/2) - (1/4) }

λ = 2.28 × 10^-8m

From the equation of light

C= fλ

C=3×10^8m/s

f = 3×10^8/2.28×10^-8

f = 1.32×10^16 hz
