Noble gas is different from other elements because it doesn't bother to bond with other elements, noble gas doesn't bond with other elements because it has the the maximum amount of valence electrons in its outer shell.

A weightless spring is stretched 10 cm by a suspended 1-kg block. If two such springs are used to suspend the block, one spring
leva [86]

Answer:

total stretch of the double-length spring will be 20 cm

Explanation:

given data

length x1 = 10 cm

mass = 1 kg

mass = double = 2 kg

to find out

the total stretch of the double-length spring will be

solution

we can say here spring constant is

k = mg    ............1

k is spring constant and m is mass and g is acceleration due to gravity

so for in 1st case and 2nd case with 1 kg mass and 2 kg mass

kx1 = mg   .........................2

and

kx2 = 2mg   ........................3

x is length

so from equation 2 and 3

\frac{kx1}{kx2}= \frac{1mg}{2mg}

\frac{x1}{x2} = \frac{1}{2}

\frac{10}{x2} = \frac{1}{2}

x2 = 20

so total stretch of the double-length spring will be 20 cm

A polarized Light of intensity I0 is incident on an analyzer. What should the angle between the axis of polarization of the ligh
Svetradugi [14.3K]

Answer:

The the angle between the axis of polarization of the light and the transmission axis of the analyzer is 52⁰.

Explanation:

Given;

I₀  as incident light intensity

The intensity of a linearly polarized light passing through a polarizer is given by Malus' law:

I = I₀Cos²θ

where;

I is the intensity after passing through the analyzer

θ is the the angle between the axis of polarization of the light and the transmission axis of the analyzer.

If 38% of the total intensity is transmitted, then I = 38% of I₀ = 0.38I₀

0.38I₀ = I₀Cos²θ

0.38 = Cos²θ

Cosθ = √0.38

Cosθ = 0.6164

θ  = Cos⁻¹ (0.6164)

θ  = 51.95° = 52⁰

Therefore, the angle between the axis of polarization of the light and the transmission axis of the analyzer to allow 38% of the total intensity to be transmitted is 52⁰.

Which would show an example of how physical changes are reversible?
kondor19780726 [428]

Answer:

Melting tin and then cooling it into a mold

Explanation:

When you melt something, and when it cools it returns to its physical state, therefore the physical changes are reversible. For example, take chocolate. When chocolate melts its liquid, then when it's in a colder situation it becomes solid again and so on, the changes are reversible.
