86 Km/h convertir a (m/min)

Physics
1 answer:
gogolik [260]3 years ago
5 0

Answer: 1433.3 m/min

Explanation:

For 86 Km/h converted to a (m/min), convert kilometers to meters, and hour to minutes

So, 86 Km/h means 86 kilometers per 1 hour

- If 1 kilometer = 1000 metres

86 kilometers = 86 x 1000 = 86,000m

- If 1 hour = 60 minute

1 hour = 60 minutes

In m/min: (86,000m / 60 minute)

= 1433.3 m/min

Thus, 86 Km/h convert to 1433.3 m/min

The energy levels of one‑electron ions are given by the equation En=(−2.18×10−18 J)(Z^2/n^2) where Z is atomic number and n is t
Alexxandr [17]

Answer:

\lambda=4.86*10^{-7}m

Explanation:

Using the given equation, we calculate the energy associated with the excited state n_i=8 and n_f=4

E_n=\frac{-2.18*10^-18J(Z^2)}{n^2}

Helium has an atomic number (Z) equal to 2, for n=8:

E_8=\frac{-2.18*10^{-18}J(2^2)}{8^2}\\E_8=-1.36*10{-19}J

For n=4:

E_4=\frac{-2.18*10^{-18}J(2^2)}{4^2}\\E_4=-5.45*10{-19}J

When an electron jumps from an energy level with greater energy E_i to one with lower energy E_f the wavelength of the emitted photon is given by:

\lambda=\frac{hc}{E_i-E_f}

h is the Planck constant and c the speed of light in vaccum. So, we have:

\lambda=\frac{hc}{E_8-E_4}\\\lambda=\frac{6.63*10^{-34}J \cdot s(3*10^8\frac{m}{s})}{-1.36*10{-19}J-(-5.45*10{-19}J)}\\\lambda=4.86*10^{-7}m

If there are 1,600 meters in a mile, find the speed of sound in this experiment in units of "miles / hour"
atroni [7]

Answer:

v = 771.75 mile / h

Explanation:

The speed of sound is v = 343 m / s  at T= 20C

the transformation ratios are

     1 mile = 1600 m

     1 h = 3600 s

Let's reduce

    v = 343 m / s (1 mile / 1600 m) (3600 s / 1 h)

    v = 771.75 mile / h
