Answer:
d). a and c
Explanation:
According to Pascal's law, when force is applied to a fluid, the pressure will increase equally in all direction of the container. Pascal law says that the pressure is transmitted undiminised in all direction inside a closed container. And the pressure inside the closed container is constant when measured at the same height above the datum.
Hence option d is correct.
Answer:
The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units
Explanation:
mpg=36.91−3.824•Engine size
Writing as y=mx+c then
mpg=−3.824•Engine size+36.91
Where mpy represent y, -3.824 represent m, engine size represent x and 36.91 represent c
Since from the equation y=mx+c m is the slope and c is the y-intercept, therefore,
The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units
Answer:
The element that is oxidized is carbon.
Its oxidation state increased. It increased from -4 to +4
Explanation:
Oxidation is a process that involves increase in oxidation number.
The oxidation number of carbon in CH4 is -4
C + (1×4) = 0
C + 4 = 0
C = 0 - 4 = -4
The oxidation number of carbon in CO2 is +4
C + (2×-2) = 0
C - 4 = 0
C = 0+4 = 4
Increase in the oxidation number of carbon from -4 to +4 means carbon is oxidized
