A object is 200 miles from the center of a circle and makes a circuit every 2 hours. How fast is it moving?

Tanya [424]

Answer: 628.31 miles/h

Explanation:

The equation to calculate the average speed $s$ of an object moving in a circular path is:

$s=\frac{2 \pi r}{T}$ (1)

Where:

$r=200 miles$ is the radius of the circumference

$T=\frac{1}{f}$ is the period, which has an inverse relation with the frequency $f=\frac{1 circuit}{2 h}=0.5 h^{-1}$ . Then $T=\frac{1}{0.5 h^{-1}}=2 h$

Solving the equation:

$s=\frac{2 \pi (200 miles)}{2 h}$ (2)

$s=628.31 miles/h$ (3)

Difference between boyles law, charles law, and gay-lussacs law

lesya [120]

Answer:

All these laws give the relationship between two quantities of the gas among V (volume), p (pressure) and T (temperature), keeping the third one constant - however the two quantities change for each law

Explanation:

Calling:

p = gas pressure

V = gas volume

T = gas temperature (in Kelvin)

We have:

- Boyle's law: the pressure and the volume of a gas kept at constant temperature are inversely proportional. Mathematically,

$pV=const.$

- Charles's law: the temperature and the volume of a gas kept at constant pressure are directly proportional. Mathematically,

$\frac{V}{T}=const.$

- Gay Lussac's law: the temperature and the pressure of a gas kept at constant volume are directly proportional. Mathematically,

$\frac{p}{T}=const.$

Which property of argon is used in light bulbs?

chubhunter [2.5K]

Answer:

Argon belongs to zero group, i.e., is a noble gas and thus is inert. Hence it will not react with the hot filaments. Hence it is used in fluorescent and incandescent light bulbs to stop the oxygen in the light bulbs from corroding the hot tungsten filament.
