Answer:

Explanation:

consider the radio wave which is electro magnetic wave used for radio communication.

  1. the wave propagates for air or vacuum.
  2. the wave presented by air is a transverse wave
  3. the radio wave speed is constant that is, equals to the speed of light as it is now electromagnetic waves.
  4. now the general relationship between frequency, speed and wavelength is given by

                         c = v/lander

               lander = c/v

Alekssandra [29.7K]

Answer:

Explanation:

Rate of flow of liquid through a tube can be expressed by the following expression

V = π P r⁴ / 8ηl

P is pressure difference between end of tube = 618 Pa

r , radius of tube = .5 x 10⁻²

η is viscosity of liquid flowing = .63  

l is length of tube = .10 m

V = 3.14 x 618 x (  .5 x 10⁻² )⁴ / (8 x .63 x .10 )

= 240.64 x 10⁻⁸ m³ /s

mass = 240.64 x 1260 x 10⁻⁸ kg / s

= 3.03 x 10⁻³ kg /s

= 3.03 gram /s .

Lolliguncula brevis squid use a form of jet propulsion to swim—they eject water out of jets that can point in different directio
romanna [79]

Answer:

a) t = 0.25 s,  b)  x = 0.075 m

Explanation:

a) For this exercise we will use kinematic relationships in one dimension

         v = v₀ + a t

in the problem they indicate the initial velocity v₀ = 0.15 m / s, the final velocity v = 0.45 m / s and the acceleration of the squid a = 1.2 m / s²

          t = \frac{v -v_o}{a}

       

we calculate

         t = \frac{0.45 - 0.15}{1.2}

         t = 0.25 s

b) We can also find the distance traveled during this acceleration

         v² = v₀² + 2a x

         x = \frac{v^2 -v_o^2 }{2a}

let's calculate

         x = \frac{0.45^2 - 0.15^2 }{2 \  1.2}

         x = 0.075 m
