Hehe first answer I’m way to cool
Either a or b. Depends on what X equals.
For example, question a.-
X+3, it has to be at least 1.
Answer b-
3X, has to be a little over 2. So I guess the most correct answer has to be A.
E = mc2. An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.
Answer:
See below ~
Step-by-step explanation:
Based on the Ideal Gas Equation,
Using T :
- V₁/T₁ = V₂/T₂
- 200/300 = 100/T₂
- T₂ = 100/200 x 300
- T₂ = 0.5 x 300
- T₂ = 150 K
Using P :
- P₁V₁ = P₂V₂
- 100 x 200 = P₂ x 100
- P₂ = 200 kPa
He can do this either by changing the temperature to <u>150</u> kelvins or by changing the pressure to <u>200</u> kilopascals.
