Answer:

Explanation:
The formula for linear expansivity, 
original length, l₁ = 123 cm = 1.23 m
final length, l₁ = 92.6 cm =0.926 m
original temperature, θ₁ = 200°C
Linear expansivity, α = 2 * 10⁻⁵ °C⁻¹
Putting these values into the formula:

Answer:
There are antiviral medicines to treat some viral infections. Vaccines can help prevent you from getting many viral diseases.
Answer:
The work done on the block by the spring as it accelerates the block is 4kx².
Explanation:
Let initial distance is x.
It was compressed three times farther and then the block is released, new distance is 3x.
The work done in compressing the spring is given by :


So, the work done on the block by the spring as it accelerates the block is 4kx².
<span>The elements of the periodic table are classified into three categories: inert gases, nonmetals and metals. Generally, inert gases do not readily gain nor lose electrons, while nonmetals are more likely to acquire electrons. Metals contain low ionization energies, which refer to the amount of energy required to free or remove an electron. These elements also have low electron affinities, or the attractive forces between an incoming electron and the nucleus of an atom. The lower the ionization energies and electron affinities of an atom are, the greater the tendency to lose electrons.</span>
