The frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.
f = v / l
so the wavlength
l = v / f
where f is the frequency
v iss the linear speed
l is the wavelength

l = ( 5100 m/s ) / ( 2.2 Mhz ) ( 10^6 hz / 1 Mhz )
f = 0.0023 m
f = 2.3 mm

If 3.61 m3 of a gas initially at STP is placed under a pressure of 2.67 atm , the temperature of the gas rises to 37.9 ∘C. What
Pavel [41]

Answer: 1.54m^3

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas at STP = 1 atm

P_2 = final pressure of gas = 2.67 atm

V_1 = initial volume of gas = 3.61m^3

V_2 = final volume of gas = ?

T_1 = initial temperature of gas at STP = 0^oC=273+0=273K

T_2 = final temperature of gas = 37.9^oC=273+37.9=310.9K

Now put all the given values in the above equation, we get:

\frac{1atm\times 3.61m^3}{273K}=\frac{2.67\times V_2}{310.9K}

V_2=1.54m^3

Thus the final volume will be 1.54m^3

Describe how a unique position of the sun , earth, and moon creates a lunar eclipse
Serggg [28]
A eclipse of the sun can only occur at a new moon when the moon passes between earth and sun. If the moons shadow happens to fall upon earths surface at a time, you'll see some portion of the suns disk covered or aka eclipsed by the moon.. I hope that helps

Who developed a unit of electric potential and electromotive force
ehidna [41]

Answer:

Alessandro Volta

Explanation:

  • Alessandro Volta composed a letter to his amigo, Sir Joseph Banks at the Royal Society of London, in March 1800. In it, Volta drew an image of his voltaic heap, an exacting heap of 24 copper and zinc plates, in addition to cardboard circles absorbed salt. Volta at that point associated copper wires to both the top and base to utilize it as power source.  
  • The voltaic heap and wires would at that point, in principle, charge something helpful, similar to a light or a little engine, however since neither existed in 1800, Volta put the two wires on the tip of his tongue. His tongue, wet with salivation, was a decent conductor and finished the circuit. Volta gave himself a decent stun, accordingly demonstrating he had made another sort of battery, or electrochemical vitality source.  
  • While researchers presently don't prescribe putting live wires on your tongue, Volta was respected for his commitments to science and we named the volt (V), or the unit of measure for electric potential, in his respect.
