A rod made up of certaon metall which had coefficiebt of volume expansion is 33×10^-6 per celsius degrer.The rod is 100 meter lo
Irina-Kira [14]

Answer:

100.11 m

Explanation:

Given:

Coefficient of volume expansion, \alpha_{v}=33\times10^{-6} /°C.

Initial length of rod, l=100 m

Change in temperature, ΔT=(90-(-10))=100 °C

We know that,

\alpha_{v}=3\alpha_{L}\\\alpha_{L}=\frac{\alpha_{v}}{3}\\\alpha_{L}=\frac{33\times10^{-6}}{3}=11\times10^{-6} /°C

Here, \alpha_{L} is the coefficient of linear expansion.

Now, we know that,

Change in length (Δl) is given as,

\Delta l=\alpha_L\times L\times\Delta T

Plug in all the values and solve for l.

This gives,

\Delta l=11\times10^{-6}\times 100\times100\\\Delta l=0.11 \textrm{ m}

Therefore, the length of rod after expansion is L+\Delta l=100+0.11=100.11 m.

Suppose mass and radius of the planet are half and twice that of earth's respectively. If acceleration due to gravity of the ear
stich3 [128]

Answer:

The acceleration due to gravity of that planet is, gₐ = 1.25 m/s²

Explanation:

Given that,

Mass of the planet, m = 1/2M

Radius of the planet, r = 2R

Where M and R is the mass and radius of the Earth respectively.

The acceleration due to gravity of Earth, g = 10 m/s²

The acceleration due to gravity of Earth is given by the relation,

                                       g = GM/R²

Similarly, the acceleration due to gravity of that planet is

                                        gₐ = Gm/r²

where G is the Universal gravitational constant

On substituting the values in the above equation

                                        gₐ = G (1/2 M)/4 R²

                                             = GM/8R²

                                             = 1/8 ( 10 m/s²)

                                             = 1.25 m/s²

Hence, the acceleration due to gravity of that planet is, gₐ = 1.25 m/s²

Which statement best describes the overall function of the human respiratory system? A. The heart pumps blood containing carbon
alex41 [277]

Answer:

C

Explanation:

<em>During respiration, oxygen diffuses into the lung (carbon dioxide diffuses out), gets into the blood, and is transported around the body. The hemoglobin of the blood distributes the oxygen to the various cells and carbon dioxide from these cells diffuses into the blood. The blood travels back to the lung where the carbon dioxide is exchanged for oxygen once again. The carbon dioxide is eventually exhaled out of the nose.</em>

The correct option is C.
