Answer:

True

Explanation:

Transmutation is known as the change of substance from one to the other substance by radioactive decays or nuclear reaction process.

The beta decay is the radioactive process in which proton is converted into neutron then there is decrease in proton number this beta decay is called positron emission beta plus decay.

If the neutron is changing into proton which means there is an increase in proton number these decay is called beta minus decay.

Therefore, by the above discussion it can be say that a radioactive decay or can say that nuclear reaction which result in a nuclei with greater than or lesser proton that the initial nuclei is called transmutation.

A 3 Hz wave has a wavelength of 0.4 m. Calculate the speed of the wave (in m/s).
anyanavicka [17]

The speed of the wave with the given frequency and wavelength is 1.2m/s.

Given the data in the question;

  • Wavelength of the wave; \lambda = 0.4m
  • Frequency; f = 3Hz = 3s^{-1}
  • Speed of the wave; v = \ ?

<h3>Wavelength</h3>

Wavelength is  the distance over which the shapes of waves are repeated. It is the spatial period of a periodic wave.

It is expressed as;

\lambda = \frac{v}{f}

Where v is velocity/speed and f is frequency.

Now, we can easily get the speed of the wave by substituting our given values into the expression above.

\lambda = \frac{v}{f} \\\\0.4m = \frac{v}{3s^{-1}}\\ \\v = 0.4m * 3s^{-1}\\\\v = 1.2ms^{-1}\\\\v = 1.2m/s

Therefore, the speed of the wave with the given frequency and wavelength is 1.2m/s.

In a given lightning flash, the potential difference between a cloud and the ground is 2.86 times 109 V and the quantity of char
Nadya [2.5K]

Answer:

Explanation:

decrease in energy of the transferred charge

= Voltage x charge

= 2.86 x 10⁹ x 23.1

= 66.067 x 10⁹ J

the final speed of the automobile be V

1/2 m v² = 66.067 x 10⁹

v² = 66.067 x 10⁹ x 2 / 1519

= .08698 x10⁹

= 87 x 10⁶

v = 9.32 x 10³ m / s
