The final speed of the  green ball : 8.5 m/s

<h3>Further explanation</h3>

Given

mass of Croquet ball = 0.5 kg

v₁= 10 m/s

v₁'= 1.5 m/s

Required

the final speed

Solution

The law of conservation of momentum

m₁v₁ + m₂v₂ = m₁v₁ '+ m₂v₂' (1=red croquet ball, 2=green croquet ball)

v₂=0 (at rest)

Input the value :

\tt 0.5\times 10+0.5\times 0=0.5\times 1.5+0.5\times v_2'\\\\5=0.75+0.5v_2\\\\4.25=0.5v_2\rightarrow v_2=8.5~m/s

_______________ are filled with special absorbing elements that move up and down between the uranium rods to keep the atoms from
d1i1m1o1n [39]

Answer:

The correct answer is - control rods.

Explanation:

Control rods are filled with special absorbing agents such as boron, cadmium, silver, and others to absorb as many neutrons as to control the fission reaction by moving them up and down in between uranium rods.

These control rods are used to prevent the nuclear reaction from getting out of control in the nuclear plant or reactor by absorbing the neutrons and prevent uranium to convert.

How many atoms are in 1.65 mol of potassium
cluponka [151]

Answer:

<h2>9.93 × 10²³ atoms</h2>

Explanation:

The number of atoms of potassium can be found by using the formula

<h3>N = n × L</h3>

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 1.65 × 6.02 × 10²³

We have the final answer as

<h3>9.93 × 10²³ atoms</h3>

Hope this helps you
