I'm not entirely sure but I would think it's A.
Answer:
The pressure corresponding to the absolute zero temperature is 0.997atm.
Explanation:
To solve this question, you draw a straight vertical line with the boiling point temperature and pressure on top of the line and the freezing point temperature and pressure on the lower part. The absolute temperature somewhere in the middle of the line with the pressure to be obtained.
So, we have;
0- (-19) / 100 - (-19) = P - 0.9267 / 1.366 - 0.9267
19 / 119 = P - 0.9267 / 0.4393
Cross multiply, we have
19 * 0.4393 = 119(P -0.9267)
8.3467 = 119P - 110.2773
119P = 118.624
P = 0.997 atm
So at 0°C, the pressure of the thermometer is 0.997atm.
Answer:
a' =4.15 m/s²
Explanation:
Given that
m= 3.2 kg
F₁ = 1.9 i −1.9 j N
F₂=3.8 i −10.1 j N
From second law of Newton's
F(net) = m a
F₁ + F₂ = m x a
1.9 i −1.9 j + 3.8 i −10.1 j = 3.2 a
a = 1.78 i - 3.75 j m/s²
The resultant acceleration a'

a' =4.15 m/s²
The positive plate is made of lead grid with a lead oxide paste coating and the negative plate is porous lead. Dilute sulphuric acid is the electrolyte. The lead acid battery produced a direct current or DC during a chemical reaction that turns lead dioxide to lead sulphate and sulphuric acid to water.
