The radioactive element radium (Ra) decays by a process known asalpha decay,in which the nucleus emits a helium nucleus. (Factoi
tamaranim1 [39]

<u>Answer:</u> The energy released in the decay process is 4.6800\times 10^{11}J

<u>Explanation:</u>

The equation for the alpha decay of Ra-226 follows:

_{88}^{226}\textrm{Ra}\rightarrow _{2}^{4}\textrm{He}+_{86}^{222}\textrm{Rn}

To calculate the mass defect, we use the equation:

Mass defect = Sum of mass of product - Sum of mass of reactant

\Delta m=(m_{Rn}+m_{He})-(m_{Ra})

We know that:

m_{Rn}=222.0176u\\m_{Ra}=226.0254u\\m_{He}=4.0026u

Putting values in above equation, we get:

\Delta m=(222.0176+4.0026)-(226.0254)=-0.0052g=-5.2\times 10^{-6}kg

(Conversion factor: 1 kg = 1000 g )

To calculate the energy released, we use Einstein equation, which is:

E=\Delta mc^2

E=(-5.2\times 10^{-6}kg)\times (3\times 10^8m/s)^2

E=-4.6800\times 10^{11}J

Hence, the energy released in the decay process is 4.6800\times 10^{11}J

Maya uses a tuning fork of frequency 250 Hz to produce transverese waves on a stretched string. Her friend justin measure the di
Goshia [24]

Answer:

The velocity of the wave is 12.5 m/s

Explanation:

The given parameters are;

he frequency of the tuning fork, f = 250 Hz

The distance between successive crests of the wave formed, λ = 5 cm = 0.05 m

The velocity of a wave, v = f × λ

Where;

f = The frequency of the wave

λ = The wavelength of the wave - The distance between crests =

Substituting the known values gives;

v =  250 Hz × 0.05 m = 12.5 m/s

The velocity of the wave, v = 12.5 m/s.

A ball is dropped from a height of 80m. The time, in seconds, it takes to reach the ground is:__________.
Aleonysh [2.5K]

Answer:

4.04 s

Explanation:

h = vi + 1/2 a t ^2

HERE  h = 80 m , vi = 0 , a =9.81 m/s^2

80 = 0 + 1/2 × 9.81 × t ^2

80 = 4.905 t^2

t^2 = 80/4.905

t ^2 = 16.30988

t = square root of 16.30988

t =  4.0385 s

t = 4.04 s

Why does a paper clip sink and a big ocean liner float? explain your answer.
slamgirl [31]

<span>Because of the density of the paperclip it sinks, but even though a boat is normally made of steal it contains an opposite force of gravity known as buoyancy. Buoyancy is the reason that a boat will float.  Boat density is less weight than the water they are in so this is one reason that they are floaters.</span>
