Answer:

Young's modulus of this tendon is $9.03\times 10^6\ N/m^2$ .

Explanation:

Given that,

Length of the tendon, l = 19 cm

It is stretched by 4.5 mm, $\Delta l=4.5\ mm$

Force, F = 11.3 N

Average diameter, d = 8.2 mm

Radius, r = 4.1 mm

The formula of Young's modulus of this tendon is given by :

$Y=\dfrac{Fl}{\Delta l A}\\\\Y=\dfrac{11.3\times 0.19}{4.5\times 10^{-3}\times \pi (4.1\times 10^{-3})^2}\\\\Y=9.03\times 10^6\ N/m^2$

So, the Young's modulus of this tendon is $9.03\times 10^6\ N/m^2$ . Hence, this is the required solution.

A closed container initially holds 50 monatomic Aparticles that have a combined energy of 480 units. After 100 monatomic B parti

Molodets [167]

Answer:

"8 units" is the appropriate answer.

Explanation:

According to the question,

Throughout equilibrium all particles are of equivalent intensity, and as such the integrated platform's total energy has been uniformly divided across all individuals.

Now,

The total energy will be:

= $480+720$

= $1200 \ units$

The total number of particles will be:

= $50+100$

= $150$

hence,

Energy of each A particle or each B particle will be:

= $\frac{1200}{150}$

= $8 \ units$

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?

melomori [17]

By using the Ohms law, we can calculate the current.

Ohms law,

$\frac{V}{I} = R$

Here, V is potential difference, and R is the resistance.

Given, $V=120 V$ and $R = 30 ohm$ .

Therefore, putting the given values in above relation , we get

$\frac{120V}{I} = 30 ohm$

or $I=\frac{120}{30} = 4 A$

Thus, the current is drawn by a television 4 Ampere
