The best answer for this question would be:

The onset of World War II

<span>It started during World War II because during the war, soldiers needed to upgrade their uniform. This is to enable them to adapt to the battlefield where the deconstruction happened and courses of history have changed.</span>

Estimate the force required to bind the two protons in the He nucleus together. (Hint: Model the protons as point charges. Assum

scoray [572]

Answer:

F = 2.30 10⁴ N

Explanation:

The force required to link two gates must be equal to or greater than the electrostatic force of repulsion, because the protons have equal charges.

F = k q₁ q₂ / r²

Where k is the Coulomb constant that is worth 8.99 10⁹ N m² / C²

In this case the proton charge is 1.6 10⁻¹⁹ C and the distance between them is approximately the diameter of the core r = 10⁻¹⁵ m

Let's calculate

F = 8.99 10⁹ (1.6 10⁻¹⁹)² / (10⁻¹⁵)²

F = 2.30 10⁴ N

The bond strength must be equal to or greater than this value

By what factor does the sound intensity increase if the sound intensity level increases from 60 db to 61 db?

tiny-mole [99]

Answer:

$\frac{I_{2}}{I_{1}} = 10^{0.1}$

Explanation:

The sound intensity level β can be mathematically defined as

$\beta(dB) = 10log_{10}(\frac{I}{I_{o} } )$

where $I_{o}$ is the reference intensity and is equal to $10^{-12}$ $W/m^{2}$ .

Now,

$\beta_{2} - \beta_{1} = 10 log\frac{I_{2} }{I_{o}} - 10 log\frac{I_{1} }{I_{o}}\\62-60= 10log(\frac{\frac{I_{2} }{I_{o} } }{\frac{I_{1} }{I_{o} } } )\\1=10log(\frac{I_{2} }{I_{1} } )\\\\\frac{I_{2} }{I_{1} }=10^{0.1}$
