Answer:
Vrms is 149.7266 m/sec

Explanation:
The root means square velocity of a gas can be calculated as follows:
Vrms = \sqrt{ \frac{3RT}{M}}
where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg

Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec

Hope this helps :)

Why do you Think you weight less on Uranus than earth even though it is more massive planet ? 
Phantasy [73]

Answer:

You would weigh less on Uranus than on Earth because Uranus is far less mass-ive and dense than the Earth. This means that there is less gravity. Therefore, you would weigh less.

Explanation:

Even though Uranus is bigger, it is less massive; that is, there is less mass that makes up the planet. The volume of the planet might be larger, but the actual amount of mass isn't.

By the way, you couldn't stand on Uranus. It's made of gas!

: How much energy is required to heat an iron nail with a mass of 25.5 grams from 65°C until it becomes red hot at 720°C?
Evgen [1.6K]

Q = mct  

-Q= energy in Joules  

-m = mass in grams  

-c= specific heat capacity in J/g degree C  

-t = delta temperature in degrees Celsius  

So,  

Q = m c t  

Q = (7 grams)(0.448J/g C)(750 C - 25 C)  

Q = 2273.6 J  

Your final answer = 2273.6 Joules

Which chemical agent will you use to modify the frog heart rate?
Leto [7]
There are different chemical agents which are used to study the heart rate of frog. Generally Ringer's solution is used to study frog's heart simulation. At different temperature, frogs heart speeds up or slows down while using Ringer's solution at experiment. Ringer's solution is mixture of salt solution which comprises of NaCl, KCl, CaCl2 and Na2CO3. Sometimes other chemicals like MgCl or antibiotics are also used as addition in Ringer's solution. 
This solution is chiefly used to study in vitro experiments on organs and tissues like frog's heart.

Ringer's solution at 23 degree Celsius for normal heart rate
Ringer's solution at 32 degree Celsius, heart rate speed up and 
Ringer's solution at  5 degree Celsius, heart rate slows down.

other chemicals also have significant effect in heart rate,
For example, Calcium ion in excess will slow down the heart rate, Atropine increases heart rate and digitalis slows down the heart rate.
