How to dispose of and safely store the active fission products in the spent fuel

Answer:

1) Accidents in the nuclear plants

2) Disposal of waste materials released from this power plants.

Explanation:

The use of nuclear power plant is quite efficient, but it contains radioactive elements that are highly radioactive and there occurs continuous emission of radiations that are harmful for health. There is no release of any green house gas and fossil fuels are not burnt.

The problems associated with the use of nuclear power plant are as follow-

Accidents in the plants- In these nuclear power plants, operations are carried out in a very careful manner, because the use of these radioactive elements releases harmful radiations, and accidents happens unexpectedly.
Disposal of waste materials- This nuclear plants releases a huge amount of waste materials that contains some amount of radioactive toxic element that are exposed to the environment causing harm to the various life forms. So it is still not solved how to handle and store this waste products.

A string attached to an airborne kite is maintained at an angle of 41 degrees with the horizontal. If a total of 152 m of string

satela [25.4K]

Answer:

The horizontal displacement is $Adj = 114.71 \ m$

Explanation:

From the question we are told that

The angle at which the string is maintained is $\theta = 41 ^o$

The length of string reeled in is $l = 152 \ m$

Using the SOHCAHTOA formula

We have that the hypotenuse(Hyp) is l = 152

Hence the horizontal displacement of the kite which is the Adjacent(Adj) can be evaluated as

$cos \theta = \frac{Adj}{Hyp }$

substituting values

$cos(41) = \frac{Adj}{152}$

=> $Adj = 114.71 \ m$

Technetium (Tc; Z = 43) is a synthetic element used as a radioactive tracer in medical studies. A Tc atom emits a beta particle

LenKa [72]

Answer : The de-Broglie wavelength of this electron, $0.101\AA$

Explanation :

The formula used for kinetic energy is,

$K.E=\frac{1}{2}mv^2$ ..........(1)

According to de-Broglie, the expression for wavelength is,

$\lambda=\frac{h}{mv}$

or,

$v=\frac{h}{m\lambda}$ ...........(2)

Now put the equation (2) in equation (1), we get:

$\lambda=\frac{h}{\sqrt{2\times m\times K.E}}$ ...........(3)

where,

$\lambda$ = wavelength = ?

h = Planck's constant = $6.626\times 10^{-34}Js$

m = mass of electron = $9.11\times 10^{-31}Kg$

K.E = kinetic energy = $4.71\times 10^{-15}J$

Now put all the given values in the above formula (3), we get:

$\lambda=\frac{6.626\times 10^{-34}Js}{\sqrt{2\times 9.11\times 10^{-31}Kg\times 4.71\times 10^{-15}J}}$

$\lambda=1.0115\times 10^{-11}m=0.101\AA$

conversion used : $(1\AA=10^{-10}m)$

Therefore, the de-Broglie wavelength of this electron, $0.101\AA$

Suppose you calculated the speed of light in an unknown substance to be 4.00x10^8 m/s. How could you tell if you made an error i

Mice21 [21]

Answer: You could tell if you made an error in your calculations by repeating the steps.

Speed of light is the fastest/maximum in vacuum which is equal to 3 × 10^8 m/s, therefore speed of light through any material equal to 4 × 10^8 m/s is physically and theoretically impossible and therefore incorrect.

Three resistors with the values of R_1, R_2, and R_3 are connected in parallel. Which of the following expresses the total resis

bagirrra123 [75]

Answer: Option d.)

R_eq = (1/R_1 + 1/R_2 + 1/R_3)^-1

Explanation:

Since, there are three resistors connected in parallel, the reciprocal of the total resistance of the resistor combination (R_eq) is obtained by adding the reciprocal of each resistance.

i.e 1/R_eq = (1/R_1 + 1/R_2 + 1/R_3)

So, R_eq = (1/R_1 + 1/R_2 + 1/R_3)^-1

Thus, the total resistance (R_eq) is equal to the inverse of the sum of the reciprocal of each resistance.

In terms of positive and negative charges what causes lightning?

erik [133]

Answer:

Electrostatic Discharge during the equalization of the separated positively and negatively charged electrostatic charges in the storm clouds.

Explanation:

In nature, lightning occurs during the discharge of the large charges contained in the separated positively and negatively particles in the atmosphere in the process equalizing (neutralizing) of the charges, leading to the release of instantaneous energy in the form of heat, light and sound

During a storm, as the clouds mixes by the wind with different densities, they rub each other forming electrostatic charges. The lighter positively charged particles rise to the top clouds while the heavier negatively charged particles move to the bottom. The charges continue to add up to a point where their magnitudes is large enough such that a big spark or lightening occurs between the positive and negative charges during the process of re-equalization of the charges to revert to neutrality.
