A bob of mass of 0.18 kilograms is released from a height of 45 meters above the ground level. What is the balue of the kinetic energy gained by the bob at the ground level?

Answers

K.E = mgh at bottom

K.E = 0.18*10*45

K.E = 81J

K.E at the bottom will be equal to P.E at hight.

If a gas occupies 22.4 L at 0.265 atm, then what will the pressure be in atmospheres if the gas occupies 35.52 L? Assume all othervariables are held constant
A)0.167 atm
B)0.437 atm
C)0.886 atm
D)149 atm

Answers

Answer:

The new pressure is 0.167 atm

The correct answer is option A

Explanation:

Step 1: Data given

Volume of the gas = 22.4 L

Pressure of the gas = 0.265 atm

The volume increases to 35.52 L

Step 2: Calculate the new pressure

P1*V1 = P2*V2

⇒with P1 = the initial pressure = 0.265 atm

⇒with V1 = the initial volume = 22.4 L

⇒with P2 = the new pressure = TO BE DETERMINED

⇒with V2 = the increased volume = 35.52 L

0.265 atm * 22.4 L = P2 * 35.52 L

P2 = (0.265 atm * 22.4 L) / 35.52 L

P2 = 0.167 atm

The new pressure is 0.167 atm

The correct answer is option A

If you bend a straight chain of carbons, do you make a different structure? Why or why not?

Answers

You only create a new structure of you add or remove atoms. The atoms in carbon chains are able to spin on their own and bend into different shapes all the time but the atoms never break or form any new bonds.
