If the wavelength of an s-wave is 23,000 m, and its speed 4500 m/s, what is its frequency?
wolverine [178]

Answer:

5 metre.

Explanation:

Wavelength = Velocity / Frequency

= 23,000/ 4,500

= 5 metre.

Two billion people jump up in the air at the same time with an average velocity of 7.0 m/sec. If the mass of an average person i
faust18 [17]

Well first of all, you must realize that it depends on how the jumpers are distributed on the earth's surface.  If,say, one billion of them are in the eastern  hemisphere and the other billion are in the western one, then the sum of all of their momenta could easily be zero, and have no effect at all on the planet.  I'm pretty sure what you must have in mind is to consider the Earth to be a block, with a flat upper surface, and all the people jump in the same direction.

average mass per person = 60 kg.
jump velocity = 7 m/s straight up and away from the block, all in the same direction
one person's worth of momentum = (m) (v) = 420 kg.m/s
sum of two billion of them = 8.4 x 10¹¹ kg-m/s all in the same direction

Earth's "recoil" momentum = 8.4 x 10¹¹ in the opposite direction = (m) (v)

Divide each side by 'm' :     v = (momentum) / (mass) =

The Earth's "recoil" velocity is   (8.4 x 10¹¹) / (5.98 x 10²⁴) = 

                                                               1.405 x 10⁻¹³ m/s =

                                              <em> 0.00000000014 millimeter per second

</em>
I have no intuitive feeling for this kind of thing, so can't judge whether
the answer is reasonable.  But my math and physics felt OK on the
way to the solution, so that's my answer and I'm sticking to it.

a battery is connected to a resistor. as charge flows, the chemical energy of the battery is dissipated as _________.
balandron [24]

As charge flows, the chemical energy of the battery is dissipated as the time of charge flow increases.

Electric power is defined as the rate at which electric energy is dissipated.

The power of the current flowing through the circuit is calculated as follows;

P = IV

P = I x IR

P = I²R

where;

  • <em>P is the power dissipated</em>
  • <em>I is the current flowing in the circuit</em>
  • <em>R is the resistance of the circuit</em>

The electric energy is given as;

E = Pt

E = I²Rt

Thus, we can conclude that as charge flows, the chemical energy of the battery is dissipated as the time of charge flow increases.
