Why does the frequency of water increase as the wavelength decreases?
Oliga [24]

Answer:

Wave speed, frequency and wavelength in refraction

Explanation:

The diagram shows that as a wave travels into a denser medium, such as water, it slows down and the wavelength decreases. Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. Hope this helps :>

You throw a stone horizontally at a speed of 5.0 m/s from the top of a cliff that is 78.4 m high.
Monica [59]

a)You throw a stone horizontally at a speed of 5.0 m/s from the top of a cliff that is 78.4 m high.

from above statement we got

height = 78.4 m

since the ball is thrown, so its vertical velocity would be zero

u = 0

taking g = 9.8m/s^2

now, using the equation of motion

h = ut + gt^2/2

now putting all the values in it

we got ,

78.4 = 9.8 * t^2/ 2

by solving we got,

t = 4 sec

b) now, since along the horizontal , no force acting and accelaration is zero so

R = ut , R is RANGE

R = 5 * 4

range =  20 m

c)  vertical components of the stone’s velocity just before it hits the ground = v sin θ =

horizontal   components of the stone’s velocity  just before it hits the ground = v cos θ

The wave speed on a string under tension is 200 m/s. What is the speed if the tension is doubled?
Maksim231197 [3]

Answer:

v = 282.84 m / s

Explanation:

The speed of a wave in a wire is given by the equation

       .v = √ T /ρ

Where v is the speed of the wave, T the tension in the wire and ρ the density of the wire

 If the tension is doubled

        T = 2T₀

        v = √ (2T₀ / ρ)

        v = √2   √ T₀ / ρ

        v = √2  v₀

calculate

       v = √2  200

       v = 282.84 m / s
