Answer : The speed of the wave is 851 m/s

Explanation :

It is given that,

Wavelength of a wave is, λ = 2.3 m

The frequency of the wave is, υ = 370 Hz

The speed of the wave is given as :

$speed=\dfrac{distance}{time}$

In case of wave, the distance is equal to the wavelength of the wave and the time taken is equal to the inverse of frequency i.e. $T=\dfrac{1}{\nu}$ .

So, $v=\dfrac{\lambda}{T}$

or $v=\nu \times \lambda$

$v=370\ Hz\times 2.3\ m$

v = 851 m/s

So, the speed of the wave is 851 m/s

A crow is flying horizontally with a constant speed of 2.70 m/s when it releases a clam from its beak. the clam lands on the roc

vovangra [49]

Part a)

in horizontal direction there is no gravity or no other acceleration

so in horizontal direction the speed of clam will remain same

$v_x = 2.70 m/s$

Part b)

In vertical direction we can use kinematics

$v_f = v_i + at$

$v_f = 0 + 2.1 * 9.8$

$v_f = 20.6 m/s$

part c)

if the speed of crow will be increased then the horizontal speed of the clam will also increase but there is no change in the vertical speed

Calculate the speed of a car that travels a distance of 2.4km in 2 minutes

hammer [34]

Answer:

72 kilometres per hour

Explanation:

The formula for calculating speed is distance/time.

So to work this out you would convert 2 minutes into hours. You would divide 2 by 60 to convert it into hours. This is because the standard unit for speed with kilometres is kilometres per hour. Then you would divide 2.4 by that.

1)Divide 2 by 60:

$2/60=0.0333333$
