Answer: 39.86 g/mol
Explanation:
Assuming this gas is at a pressure of 
and a temperature of 
, we can solve this problem with the Ideal Gas Law equation:
(1)
Where:
is the pressure of the gas
is the volume of the gas
the number of moles of gas
is the gas constant
is the absolute temperature of the gas in Kelvin
On the other hand, we know the density 
is given by a relation between the mass 
and the volume :
(2)
Then, the mass is:
(3)
Another important fact here is that the molar mass 
of an element is given by a relation between the mass of that element and the number of moles it contains:
(4)
Isolating :
(5)
Substituting (5) in (1):
(6)
Substituting (3) in (6):
(7)
Isolating :
(8)
Simplifying:
(9)
Solving with the given data:
(10)
Finally:
This is the molar mass of the gas
Answer:
The answer is option C.
Explanation:
The question is not complete, here is the complete question:
A person picks up a heavy suitcase in order to estimate its weight and reflexively drops it. Which of the following receptors has initiated this reflex?
A) Free Nerve Ending
B) Lamellae Corpuscle
C) Tendon Organ
D) Bulbous Corpuscle
The answer is option C, the tendon organ. Tendon organ, located in the skeletal muscles, takes on the role of sensing the tension in the muscle so that it can be adjusted appropriately. In this case, the weight of the suitcase was not estimated correctly so the tension of the skeletal muscle was not enough to hold the suitcase.
I hope this answer helps.
Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Answer:
Speed is directly proportional to position and inversely proportional to time.
Explanation:
Increase in speed means covering a larger distance in a small time
