Answer:

A bomb that is dropped from a moving helicopter doesn't fall directly downward rather it follows the parabolic path as it were thrown horizontally from a height with certain initial velocity. Therefore, the bomb should be dropped from farther distance equal to the horizontal range before the helicopter reaches above the target.

Calculate the number of free electrons per cubic meter for some hypothetical metal, assuming that there are 1.3 free electrons p

boyakko [2]

Answer:

The number of free electrons per cubic meter is $7.61\times 10^{28}\ m^{-3}$

Explanation:

It is given that,

The number of free electrons per cubic meter is, 1.3

Electrical conductivity of metal, $\sigma=6.8\times 10^7\ \Omega^{-1}m^{-1}$

Density of metal, $\rho=10.5\ g/cm^3$

Atomic weight, A = 107.87 g/mol

Let n is the number of free electrons per cubic meter such that,

$n=1.3\ N$

$n=1.3(\dfrac{\rho N_A}{A})$

Where

$\rho$ is the density of silver atom

$N_A$ is the Avogadro number

A is the atomic weight of silver

$n=1.3\times (\dfrac{10.5\ g/cm^3\times 6.02\times 10^{23}\ atoms/mol}{107.87\ g/mol})$

$n=7.61\times 10^{22}\ cm^{-3}$

$n=7.61\times 10^{28}\ m^{-3}$

Hence, this is the required solution.

What is the final velocity of a dragster that travels 400 meters from the start line

krek1111 [17]

Answer:

80m/s

Explanation:

The formula for velocity is [ v = s/t ] where s = displacement and t = time.

= 400/5

= 80m/s

Best of Luck!

Why is hygiene a valued health practice in workout facilities?

MariettaO [177]

This is one method of how infectious diseases like skin infections spread. Keeping the gym clean is essential to maintaining everyone's health and safety.

<h3>Which skin illness is the worst?</h3>

Necrotising fasciitis is just a severe infection of the skin, including tissue beneath the skin, and the fascia (the fibrous tissue that divides muscles and organs), which causes necrosis, or the death of tissue. If not identified and treated promptly, the infection spreads quickly, is lethal.

<h3>A skin infection: how do you treat it?</h3>

Depending on the infection's origin and intensity, different treatments are available. It may take days or weeks for some viral skin infections to heal on their own. Antibiotics taken orally or administered topically to the skin are frequently used to treat bacterial infections.
