Is absolute zero point measured by interval or ratio scale?
Ratio
What are the direction of two vectors when their resultant is zero?
opposite
Two vectors have nonzero magnitudeunder what conditions will their difference be zero?
Their DIFFERENCE will be zero if and only if they have the SAME direction.
How many seconds is 10 trillion years?
Zero. There was no time measured that long ago.
What is the definition of x coordinate?
In the system of Cartesian coordinates in geometry, the x-coordinate is the location in the horizontal direction (nominally left and right) while the y-coordinate is in the vertical direction (up and down). The line along which x values are measured is the x-axis. An x-coordinate to the left of center (zero) is negative, and to the right is positive. (In three dimensions, the x and y form a horizontal plane and the z coordinate is measured along the vertical axis.)
Is absolute zero measured in kelvins?
Yes, absolute zero is zero degrees Kelvin.
Does the phrase direction of zero vector have physical significance?
No. the zero vector has no direction, therefore it has no significance.
What is the temparature of absolute zero measured in celsius?
Zero Kelvin is -273.15oC
If a vector has constant direction then?
There is almost never an "IF". All non-zero vectors have a constant, specified direction. Only a zero-vector has a direction which is unspecified.
When two equal and opposite vectors are added their resultant vector has zero magnitude what is the direction of this resultant?
The zero-vector has no direction.
Can a body have acceleration without velocity?
Yes. Velocity is speed per unit of time with a direction vector telling you which way the object in question is moving. Acceleration is a change in velocity - in any part of velocity. If something like, say, a rock is in deep space (a zillion light years from anything) and it's moving along unaffected by any gravity or other forces, it has some velocity (some speed in a given direction, or is moving at some distance per unit of time in a given direction), but it isn't changing speed or direction. If something is moving without changing its speed or its direction (either of which requires a force to act on the object - to accelerate the object), it has zero acceleration. Such an object is said to have a constant velocity and will have zero acceleration. Certainly if an object is not moving, it has zero velocity and zero acceleration, but that's probably not what is being asked. It has velocity (zero) and no acceleration. To recap, an object can have a non-zero velocity and zero acceleration.
What is the name of the zero line from which latitude is measured?
The equator
Can an object change its direction when the magnitude of its velocity is zero?
If the velocity is zero, the object is not moving. So if it moves at all, it is changing direction.
How can amplitude be measured?
It can be measured from zero to the highest value vertically.This can be done with specific meters depending what you are measuring
What is the acceleration from 0 to 2s?
-- Its magnitude is 1/2 of [ (the speed at 2 seconds) minus (the speed at zero) ]. -- Its direction is 1/2 of [ (the direction at 2 seconds) minus (the direction at zero) ].
What is the temperature of absolute zero measured C?
-273 C
What is the conductivity of chloroform?
I measured it to be zero, but need some confirmation.
