PLEASE PLEASE HELP!!

QveST [7]

Explanation:

(1) We have,

Wavelength of a wave is 2 meters

Frequency of a wave is 6 Hz

It is required to find the velocity of a wave. The velocity of a wave is given by :

$v=f\lambda\\\\v=2\times 6\\\\v=12\ m/s$

So, the velocity of a wave is 12 m/s.

(2)

Number of waves passing are 100

Time taken to pass the wave is 5 seconds

The frequency of wave is given by total number of waves passing per unit time. So,

$f=\dfrac{100}{5}\\\\f=20\ Hz$

Frequency of a wave is 20 Hz.

There is a maximum depth at which a diver can breathe through a snorkel tube because as the depth increases, so does the pressur

hammer [34]

Answer: $59.78\times 10^3\ Pa$

Explanation:

Given

Diver is at a depth of $h=6.1\ m$ inside the water $(\rho=10^3\ kg/m^3)$

As we go down pressure increases due to the weight of liquid column above us

Pressure difference is given by $P=\rho \times g \times h$

Where $\rho$ =density of liquid

h=depth

g=acceleration due to gravity

So external-internal pressure difference is

$\Delta P=10^3\times 9.8\times 6.1$

$\Delta P=59.78\times 10^3\ Pa$
