Answer:

Mechanical waves.

Explanation:

A mechanical wave is a perturbation on the mechanical properties of the material medium (position, velocity, pressure, etc. ) in which it propagates.

Mechanical waves need a source that creates the perturbation and, a physical medium in which perturbation propagates, the medium can be a gas, a liquid or, a solid.

Some examples are sound, earthquakes and, waves on a guitar string.

Answer:

here given is a weight

then force becomes mg

that is F=Mg

=4*9.8

then by using the formula

We repeat the experiment from the video, but this time we connect the wires in parallel rather than in series. Which wire will n

iragen [17]

Answer:

The copper wire (resistance 0.1 Ω )

Explanation:

In a parallel connection, the same voltage is maintained across all the resistors but the current varies.

The larger the magnitude of the resistance, the smaller the current flowing in the circuit and the smaller the heat dissipated by the resistor.

Hence the copper wire dissipates the greatest heat.

Calculate the time required (in years) for water to penetrate a layer of clay that is 40 cm deep when exposed to a hydraulic gra

guapka [62]

Answer:

The time required to penetrate the 40 cm clay layer is 126.82 years

Explanation:

Given:

Hydraulic gradient = 1 $\frac{cm}{cm}$

Permeability of clay $K = 1 \times 10^{-8}$ $\frac{cm}{sec}$

Time required to penetrate 40 cm clay layer,

$= \frac{40}{K}$

$= \frac{40}{1 \times 10^{-8} }$

$= 40 \times 10^{8}$ sec

But we have to find time in years,

$= \frac{40 \times 10^{8} }{24 \times 60 \times 60 \times 365}$ years

$= 126.82$ years

Therefore, the time required to penetrate the 40 cm clay layer is 126.82 years
