Which nucleus completes the following equation?

Physics
2 answers:
natali 33 [55]3 years ago
8 0

Answer:

_{84}^{208}Po

B is correct.

Explanation:

Given the equation

_{86}^{212}Rn\rightarrow_{2}^{4}He

According to alpha emission

Alpha emission is a radioactive decay in which the atomic nucleus emit the alpha particle and formed a new nucleus whose mass number reduced by four and atomic number reduced by two.

Therefore,

Po is the new nucleus.

_{86}^{212}Rn\rightarrow_{2}^{4}He+_{84}^{208}Po

Where, Rn = Radon

Po= polonium

Who knows the egg drop challenge
liubo4ka [24]
I know. If you're asking for ideas, I once did one and it did not break. I just took a cardboard box, filled it with thins like packing peanuts, crumpled newspaper, and put the egg inside a few layers of socks in the middle, and taped the box tightly shut. Our science teacher dropped from the roof of the school, and there wasn't even a crack on mine!

A change in the gene pool of a population due to chance is _____.
Mrac [35]
<span>The correct answer should be a genetic drift. Mutations usually occur over a relatively short period of time and usually start with a single unit that transfers the mutation when they procreate. Genetic drifts separate entire populations and in time create new species that cannot procreate with the original species from whence they came.</span>

Basketball player Darrell Griffith is on record as
Gre4nikov [31]

Explanation:

1.

We use the equation

h = \frac{gt^2}{2}, where

h is the height traveled,

g is the acceleration due to gravity and

t is the time taken to reach height h.

We can now calculate t to be

\sqrt{\frac{2*1.2 m}{9.81 m/s^2} }

= 0.495 s

Let v be the initial velocity of the player.

The player deaccelarates from v m/s to 0 m/s in 0.495 s at the rate of 9.81 m/s^2.

v = 9.81 m/s^2 x 0.495 s = 4.85 m/s

2.

The player takes 0.3 s to increase his velocity from 0 m/s to 4.85 m/s. So his average accelaration is

4.85 m/s / 0.3 s = 16.2 m/s^2

an ice skater applies a horizontal force to a 20.-kilogram block on frictionless, level ice, causing the block to accelerate uni
stiv31 [10]
The only vertical forces are weight and normal force, and they balance since the surface is horizontal. The horizontal forces are the applied force (uppercase F) in the direction the block slides and the frictional force (lowercase f) in the opposite direction.

Apply Newton's 2nd Law in the horizontal direction:
ΣF = ma
F - f = ma
where f = µmg

F - µmg = ma
F = m(a +µg)
F = (20 kg)(1.4 m/s² + 0.28(9.8 m/s²)

F = 83 N
