Fused quartz possesses an exceptionally low coefficient of linear expansion, 5.50 × 10 − 7 ( ∘ C ) − 1 . Suppose a bar of fused

EastWind [94]

To solve this problem it is necessary to apply the concepts related to thermal linear expansion. Mathematically this concept can be expressed under the Equation:

$\Delta L = L_0 \alpha \Delta T$

Where,

$L_0 =$ Initial Length

$\alpha =$ Thermal Expanssion constant

$\Delta T =$ Change in Lenght

Our values are given as

$L_0 = 2.99m$

$\alpha = 5.50*10^{-7} ( \∘C )^{-1}$

$\Delta T = T_2-T_1 = 213-20$

Replacing at our equation we have,

$\Delta L = L_0 \alpha \Delta T$

$\Delta L = (2.99) (5.5 x 10^{-7}) (213 - 20)$

$\Delta L = 0.317*10^{-3}m\approx 0.317mm$

Therefore the expantion of the bar is 0.317mm

A 12 ohm resistor and a 24 ohm resistor are connected in parallel across a 6.0 V battery. The correct statement from the followi

Gala2k [10]

Answer:

d. the voltage difference between the ends of each resistor is the same.

Explanation:

A resistor is a circuit component that offers opposition to the flow of current. Resistors may be connected in series or in parallel.

Resistors in parallel are connected at common junctions. The potential difference (voltage difference between the ends of each resistor) is the same for each resistor in a parallel connection while the current across each resistor is different.

Genrish500 [490]

Answer:

v = 0.0251 km/h

Explanation:

Given that,

The average distance from its center of mass of 1000 meters.

The time taken is 24 hours and 57 minutes to complete one orbit

We need to find the orbital velocity of the spacecraft OSIRIS-REx.Let it is v. SO,

$v=\dfrac{2\pi r}{t}$

Putting all the values,

$v=\dfrac{2\pi \times 100}{24\ hours\ and\ 57\ minutes}\\\\v=\dfrac{2\pi \times 100}{(86400+3420)}\\\\v=0.00699\ m/s$

or

v = 0.0251 km/h

So, the average orbital velocity is 0.0251 km/h.
