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>

The planet Saturn has a mass that is 95 times Earth's mass and a radius that is 9.4 times Earth's radius. What is the accelerati
ziro4ka [17]

Answer:

10.55111 m/s²

Explanation:

M = Mass of Saturn = 95\times 5.972\times 10^{24}\ kg

r = Radius of Saturn = 9.4\times 6.371\times 10^6\ m

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

Acceleration due to gravity is given by

g=\dfrac{GM}{r^2}\\\Rightarrow g=\dfrac{6.67\times 10^{-11}\times 95\times 5.972\times 10^{24}}{(9.4\times 6.371\times 10^6)^2}\\\Rightarrow g=10.55111\ m/s^2

The acceleration due to gravity on Saturn is 10.55111 m/s²

Real springs have mass. How will the true period andfrequency
Ad libitum [116K]

Explanation:

An perfect mass less spring, attached at one end and with a free mass attached at the other end, will have a distinct frequency of oscillation depending on its constant spring and mass. On the other hand, a spring with mass along its length will not have a characteristic frequency of oscillation.

Alternatively, based on its spring constant and mass per length, it will now have a wave Speed. It would be possible to use all wavelengths and frequencies, as long as the component fλ= S, where S is the spring wave size. If that sounds like longitudinal waves, like solid sound waves.

Why do plants produce their own food
Serhud [2]

Because way back, when there were some kinds of plants that made
their own food, and other kinds of plants that depended on dinosaurs or
people to bring them food, guess which ones starved and became extinct,
and which ones lived and are still among us today.

g What is the specific heat of silver? The molar heat capacity of silver is 25.35 J/mol⋅∘C. How much energy would it take to rai
disa [49]

Answer:

38.6 J

Explanation:

c = molar heat capacity of silver = 25.35 J/(mol °C)

m = given mass of silver = 9.00 g

M = Molar mass of silver = 108 g

n = Number of moles of silver

Number of moles of silver are given as

n=\frac{m}{M}

n=\frac{9}{108}

n = 0.0833

Q = Energy needed to raise the temperature

ΔT = Change in temperature = 18.3 °C

Energy needed to raise the temperature is given as

Q = n c ΔT

Q = (0.0833) (25.35) (18.3)

Q = 38.6 J
