Is instantaneous velocity a vector quantity?
YES!!! Because velocity is speed in a given direction(vector). e.g 30 mph is a scalar quantity, but '30 mph in a northerly direction' is a vector quantity, because it has direction.
What is formula for aceleration?
There are, of course, several formulae that involve acceleration. The basic definition of acceleration is: acceleration = delta velocity / delta time, that is, to get average acceleration, divide the difference of velocity by the time that passed. The same formula also gives you the instant acceleration, if the acceleration is constant. If you want to get instantaneous acceleration, and the acceleration changes, then you need calculus: acceleration = dv / dt (that is, take the derivative of the velocity).
What is the definition of instantaneous velocity?
Instantaneous velocity:Suppose the velocity of the car is varying, because for example, you're in a traffic jam. You look at the speedometer and it's varying a lot, all the way from zero to 60 mph. What is the instantaneous velocity? It is, more or less, what you read on the speedometer. I'm assuming you've got a good speedometer that isn't too sluggish and can change its reading quite quickly. Your speedometer is measuring the the average velocity but one measured over quite a short time, to ensure that you're getting an up to date reading of your velocity.So if you measure the displacement of the car over a time , you can use that to determine the average velocity of the car. What we want is to take the limit as goes to zero.Most of the time we'll be working with instantaneous velocity, so we'll just drop the instantaneous, and call the above vthe velocity.To justify that such a limit exists is something that you've hopefully had to grapple with already. For physics problems, this limit does indeed exist and gives the derivative
What is the mathematical equation of velocity?
v = Δdt / Δt Average velocity = Total displacement / time If you want to be more specific: v = ds/dt Instantaneous velocity = derivative of displacement with regard to time
Might pasting in excel with relative references ever produce the wrong result?
Yes. It depends on the formula and what you want the formula to do. So it is easy to have the wrong formula and paste it, or have the correct formula initially, but when it is pasted elsewhere it does not use the correct values. Normally if you have your worksheet set up correctly then once the initial formula is correct, pasting it to the right place should not cause any problems.
What is the formula for the angular velocity?
There are several, what is it that you want to calculate? The "natural" units for angular velocity are radians/second. The relationship between linear velocity and angular velocity is especially simple in this case: linear velocity (at the edge) = angular velocity x radius.
What is the correct way to write magnesium oxide?
Did you want the formula? If so it is MgO.
What is the formula for aceleration?
The first answer is backward. Acceleration = (final velocity - initial velocity)/total time. For deceleration the formula is the same, the answer will just be negative.Agreed. In physics, there is no "deceleration", only negative acceleration.a = Δv / ΔtThere is no equation for "deceleration" as suggested below.Deceleration=(original velocity-final velocity)/TimeDeceleration In MotionDeceleration = inital speed - final speed / total time taken
Which of these is the correct formula for nitrogen tribromide?
If you want to ask questions about "which of these", then I suggest that you make sure that there is something that is following.
In Microsoft Excel you want to use this if statement ife8yescorrectfalse how do you make the if statement cell blank if there is no text in cell e8?
If the word Yes is in E8, the following formula will put Correct in the cell that the formula is in, or else leave it blank, which is done by have a two sets of double quotes with no gap between them after the final comma. =IF(E8="Yes","Correct","") You can exchange the Yes with whatever you are testing for and the Correct with whatever you want to put in the cell. Another thing you can do is use the IsBlank function to test if the cell is empty. If it is empty it will leave the cell with the formula blank or will put the word Correct in, no matter what is in the cell E8 if it is not blank. That may not be exactly what you want to do, but this would be the formula. =IF(IsBlank(E8),"","Correct") If you want to allow numbers to be in the cell, but no text you could use the IsText function: =IF(Not(IsText(E8)),"","Correct") Probably the first formula or a slight variation of it is what you are looking for.
Where should a service valve be installed to an instantaneous electric water heater?
The 100%correct answer is as close as possible , because you don’t want to run around the building to close the tab .
An easy way to verify that a formula references the cells that you want it to reference is to use Excel's?
Range finder. Double clicking on the formula activates the range finder and you can see what cells are in the formula. This can help you see if the correct cells are in the formula.
