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 lines are parallel to a given line through a given point?
zero
How many seconds is 10 trillion years?
Zero. There was no time measured that long ago.
What is the direction of zero vector?
The zero vector has no direction because it has a magnitude of zero. It is represented by a point at the origin in a coordinate system, with no specific direction.
Does the phrase direction of zero vector have physical significance?
No, the zero vector has no direction as it does not have magnitude or point in any specific direction. It represents a point in space with no displacement.
What is the temparature of absolute zero measured in celsius?
Zero Kelvin is -273.15oC
When the velocity of a particle is constant its acceleration is also constant?
When the velocity of a particle is constant, it means there is no change in speed or direction. Therefore, its acceleration is zero because acceleration is the rate of change of velocity. If the velocity is constant, there is no change to be measured, so the acceleration is constant at zero.
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.
Is absolute zero measured in kelvins?
Yes, absolute zero is measured as 0 Kelvin on the Kelvin scale. At this temperature, particles have minimal thermal energy and cease all motion.
Can an object change its direction when the magnitude of its velocity is zero?
No, an object cannot change its direction when the magnitude of its velocity is zero. This is because velocity is a vector quantity that includes both magnitude and direction. If the magnitude of the velocity is zero, it means the object is not moving at all and therefore cannot change direction.
What is the name of the zero line from which latitude is measured?
The equator
What is true about velocity of a moving car?
The velocity of a moving car is a vector quantity that includes the speed and direction of the car's motion. It can be positive, negative, or zero, depending on the direction the car is moving. It is typically measured in units such as meters per second or miles per hour.
Can an obeject be in equilibrium if the only torques acting on it produce clickwise rotation?
No, for an object to be in equilibrium, the net torque acting on it must be zero. If all torques are producing clockwise rotation, there will be a net torque causing the object to rotate in that direction, not in equilibrium.
Can a body have acceleration without velocity?
Yes, a body can have acceleration without velocity. This can occur if the body is changing its direction or speed while its velocity is zero at a particular moment. For example, a car at rest that suddenly accelerates forward experiences acceleration without velocity initially.
What is the temperature of absolute zero measured C?
-273 C
