This is alpha decay not beta decay. 

<span>Fermium 257 decays by ALPHA decay into 253 Cf which has an atomic number of 98 </span>

<span>So your reaction is </span>

<span>257Fm --> 253Cf...+ 4He </span>
<span>100................98.........2 </span>


<span>Interestingly Californium does undergo beta decay. </span>

<span>253Cf ---> 253Es + e- </span>
<span>98...............99 </span>

<span>Hope this helps.</span>

An fm radio station broadcasts at 98. 6 mhz. What is the wavelength of the radiowaves?.
victus00 [196]

The wavelength of the radio waves is 3.04 cm.

<h3>Calculation:</h3>

λf = c

λ = c/f

where,

λ = wavelength

c = speed of light

f = frequency

Given,

f = 98.6 MHz = 98.6 × 10⁶

c = 3 × 10⁸

To find,

λ =?

Put the values in the formula,

λ = c/f

λ = 3 × 10⁸/98.6 × 10⁶

  = 0.0304 × 10²  m

  = 3.04 cm

Therefore, the wavelength of the radio waves is 3.04 cm.

What does Newton's third law describe?
Vesnalui [34]

Answer:

Newton's third law is: For every action, there is an equal and opposite reaction.

Explanation:

The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
