What else can I help you with?
Is it possible for absolute pressure to be negative?
No, absolute pressure cannot be negative as it is always measured as a positive value above zero.
Can a diastolic blood preasure reading be zero with a systolic of 110?
In many pregnant women, the 4th phase karatkoff sound is audible even though there is no pressure in the cuff. Hence, this leads to a 5th phase karatkoff sound (diastolic pressure reading) of 0. So yes, a systolic reading of 110 and a diastolic of 0 is possible - an example would be in pregnancy.
Why will pressure or volume never equal to zero?
Pressure and volume cannot be equal to zero because absolute zero pressure and volume represent the absence of matter or particles. In reality, there will always be some amount of gas particles present, even if it is very low, which will result in a non-zero pressure and volume.
What is absolute zero pressure?
absolute pressure is calculated from a vacuum (0 psi) and atmospheric pressure is14.7psia or 14.7 psi above a vacuum 1psi on a tire pressure gauge is called 1psig = 15.7psia 10psig=24.7psia 100psig=114.7psia etc.
What is the corresponding number for the temperature of -7 degrees below zero?
-7 degrees below zero is 7 degrees above zero.-7 degrees below zero is 7 degrees above zero.-7 degrees below zero is 7 degrees above zero.-7 degrees below zero is 7 degrees above zero.
Is a quotient of zero and a negative number always zero?
Zero divided by anything is always zero.
Why is the atmospheric pressure on moon is zero?
The atmospheric pressure on the moon is essentially zero because the moon does not have a significant atmosphere. Unlike Earth, which has a dense atmosphere that exerts pressure due to the weight of the air above us, the moon lacks this gaseous envelope and thus has almost no atmospheric pressure.
What multiples always end in zero?
Anythingmultipliedby zero always ends in zero.
What is the first number above zero?
There is no first number above 0. If x was considered to be the first number above zero then x/2 would be above zero but nearer to it. And then half that number would be above zero and nearer still. And so on.
Will the opposite of zero always or never be zero?
The opposite of zero - in the sense of additive inverse - is zero.
What does blood pressure readings mean?
To push a fluid mixture such as blood through tubes pressure (force) must be applied, in the case of blood the pressure is applied by the heart. Blood pressure has two readings systolic and diastolic. Systolic pressure it the higher pressure. It actually pushes the blood through the blood vessels when the heart contracts (beats/pumps). Diastolic is the minimum pressure that happens when the heart has finished a beat and is refilling with blood for the next beat. The pressure is never zero because the vessels or tubes that carry the blood are stretched and are squeezing on the blood even when the heart is not pushing. Both the systolic and diastolic pressures are important. If these pressures get high for a short period (unless the systolic is extremely high) it's not usually a problem. But, if the systolic remains too high for long periods it stresses the heart and the vessels and over time can cause either to fail. If the diastolic is too high it never lets the heart and vessels rest/relax which can also cause failures over time.
Does a graph of a linear equation always have an x intercept?
No; if the slope is zero and it is above or below y=0 it will not have an x intercept.
