What results from splitting an atomic nucleus

2 answers:

7 0

A uranium-235 atom absorbs a neutron and fissions into two new atoms (fission fragments), releasing three new neutrons and some binding energy. ... Several heavy elements, such as uranium, thorium, and plutonium, undergo both spontaneous fission, a form of radioactive decay and induced fission, a form of nuclear reaction.

Express the answer to 4.31x10^7 multiplied by 5.41x10^5 scientific notation.

I am Lyosha [343]

Answer:

The product of the two numbers is 2.33* 10^13

Explanation:

Given

4.31x10⁷ and 5.41x10⁵

Required

Multiply

The multiplication of the two digits is represented as thus:

$Result = 4.31 * 10^7 * 5.41 * 10^5$

This can also be rewritten as

$Result = 4.31 * 5.41 * 10^7 * 10^5$

Multiply 4.31 and 5.41

$Result = 23.3171 * 10^7 * 10^5$

Apply laws of indices

$Result = 23.3171 * 10^{7+5}$

$Result = 23.3171 * 10^{12}$

The scientific notation is always in the form: $a * 10^n$

Where $1 \leq\ a \leq 10$

So:

23.3171 can be rewritten as 2.33171 * 10

So, we have:

$Result = 2.33171 * 10* 10^{12}$

Also, apply law of indices again

$Result = 2.33171 * 10^{1+12}$

$Result = 2.33171 * 10^{13}$

It's always advisable (but not compulsory to approximate to 1 or 2 decimal places)

So:

$Result = 2.33* 10^{13}$

Hence; the product of the two numbers is 2.33* 10^13

To maintain the same amount of torque due to a mass on a balance as the mass is increased, how should the position of the mass c

olasank [31]

Answer:

the mass should be bring closer to the point about which we are finding torque

Explanation:

τ = Σr × F = rmg

where m is the mass, g is acceleration due to gravity, and r is the distance

Torque is directly proportional to -

1.mass, m , of object

2. distance, r, of the mass from the point about which we are finding the torque.

So if we increase or decrease them then the torque will also increase or decrease.

So if we increase the mass the torque will increase but since we have to maintain same torque therefore we have to decrease the distance of mass from the point about which we are finding torque.

Therefore the mass should be bring closer to the point about which we are finding torque.

Light enters air from water. The angle of refraction will be A. less than the angle of incidence. B. greater than or equal to th

Rina8888 [55]

Answer:

E. greater than the angle of incidence.

Explanation:

Snell's law states that:

$n_i sin \theta_i = n_r sin \theta_r$ (1)

where

$n_i, n_r$ are the refractive index of the first and second medium

$\theta_i, \theta_r$ are the angle of incidence and refraction, respectively

For light moving from water to air, we have:

$n_i = 1.33$ (index of refraction of water)

$n_r = 1.00$ (index of refraction of air)

Substituting into (1) and re-arranging the equation, we get

$\sin \theta_r = \frac{n_i}{n_r} sin \theta_i = 1.33 sin \theta_i$

which means that

$\theta_r > \theta_i$

so, the correct answer is

E. greater than the angle of incidence.

Suppose that 2 scientists use different measurement systems in their work. What problems might arise if they shared their data?

bixtya [17]

In assumption that there were two scientists who used different measurement systems in their research. The problems that might arise if they shared their data is obviously and primarily error. Errors are recognized and one element in every measure, system and quantity. Error was already even present in the measurement system alone a scientist used and it will furthermore aggregate, when these two different scales are combined the more error escalates in the process. There are two types: random and systematic error.
