A very flexible helium-filled balloon is released from the ground into the air at 20. ∘c. The initial volume of the balloon is 5

. 00 l , and the pressure is 760. Mmhg. The balloon ascends to an altitude of 20 km , where the pressure is 76. 0 mmhg and the temperature is − 50. ∘c. What is the new volume, v2 , of the balloon in liters, assuming it doesn't break or leak?

The new volume, v2, of the balloon in liters, assuming it doesn't break or leak, is 38.0546 L. To perform the calculation we will use the Boyle-Gay-Lussac law gas equation.

<h3 /><h3>What is the Boyle-Gay-Lussac law?</h3>

It is shown that the volume of the gas is inversely proportional to its pressure, while its volume is directly proportional to its temperature and constant pressure.

  • P1 x V1/T1 = P2 x V2/T2

P1= Initial gas pressure

V1= Initial gas volume

P2= Final gas pressure

V2= Final volume of gas

T1= Initial gas temperature (Kelvin)

T2= Final gas temperature

Substituting the values ​​in the formula, we have:

  • 760 x 5 / 293 = 76 x v2 / 223
  • v2 = 38.0546 L

Ingrid is participating in a relay race. While jogging at 9 km/h, she tosses a relay stick at 16 km/h to her teammate, who is st
Katena32 [7]

Answer:

16 km/h

Explanation:

The relay stick would have the same velocity relative to Ingrid as the velocity she threw it because she threw it while running 9 km/h and the question asks for how fast it is moving RELATIVE to Ingrid, who also started off moving at 9 km/h.

Sorry if explanation is bad, this one was a bit of head scratcher for me to wrap my head around ig.

Kindly :( can anyone give me an example of the chart above ?
Reil [10]
Sin(30°) =1/2 0.5

cos(30°) = (√3)/2


Note that the sin of an angle is equal to the cos of the complementary angle:

sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)

Brrunno [24]

The trial natriuretic peptide(ANP) is a hormones that will not stimulate changes that lead to an increase in arterial blood pressure.

<h3>What is a arterial blood pressure?</h3>

This refers to the force that is exerted by the blood on the arterial wall.

Hence, the hormones that will stimulate changes that lead to an increase in arterial blood pressure includes the Antidiuretic hormone (ADH), Aldosterone, Angiotensin and Epinephrine

Therefore, the Option A is correct.
