What are they wats to find the wavelength of a transverse wave

1 answer:

3 0

The wavelength can always be determined by measuring the distance between any two corresponding points on adjacent waves. In the case of a longitudinal wave, awavelength measurement is made by measuring the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

A 2.0 kg wooden block is slid along a concrete surface (μk = 0.21) with an initial speed of 15 m/s. How far will the block slide

exis [7]

Answer:

The distance is 54.6 m

Explanation:

Given that,

Mass = 2.0 kg

Frictional coefficient = 0.21

Initial velocity = 15 m/s

We need to calculate the acceleration

Using formula of frictional force

$F = \mu mg$

$F=0.21\times2.0\times9.8$

$F = 4.12\ N$

We need to calculate the acceleration

$F = ma$

$a = \dfrac{F}{m}$

$a =\dfrac{4.12}{2.0}$

$a=2.06\ m/s^2$

We need to calculate the initial velocity

Using equation of motion

$v^2=u^2-2as$

Put the value

$0=15^2-2\times2.06\times s$

$s = \dfrac{15^2}{2\times2.06}$

$s=54.6\ m$

Hence, The distance will be 54.6 m.

Difference between good and bad conductors of heat

uranmaximum [27]

Good conductors are the materials which allow electricity to pass through them easily whereas, bad conductors are the materials which do not allow electricity to pass through them. Good conductors offer less resistance to the flow of current, whereas the bad conductors do not transmit current through them.
