What is the combining of velocities known as?
The combining of velocities is known as velocity addition or relative velocity. It involves adding or subtracting the velocities of two objects moving relative to each other.
Which of the following must always be measured or described relative to something else?
Quantities such as speed, temperature, and position must always be measured or described relative to a reference point or standard in order to have meaning. For example, speed is measured relative to a specific point in time, temperature is measured relative to a chosen scale, and position is described relative to a coordinate system.
What is relative velocity for two bodies A and B with velocities Va and Vb in the same direction?
If the velocities are equal from my point of view, then I see them both moving at the same speed and in the same direction. That means that from the point of view of an observer riding on either body, the other one is standing still. Their relative velocity is zero. This is exactly the situation with a passenger and the book she's reading, both in an airliner flying west at 400 mph.
What is the relative amount of kinetic energy?
Kinetic energy is proportional to the square of an object's velocity, so the relative amount of kinetic energy depends on the velocities of the objects in question. If one object is moving faster than another, it will have more kinetic energy. The ratio of their kinetic energies will be the square of the ratio of their velocities.
What is the difference between absolute and gauge pressure?
Absolute pressure is measured relative to a perfect vacuum, while gauge pressure is measured relative to atmospheric pressure.
What is the combining of velocities known as?
The combining of velocities is known as velocity addition or relative velocity. It involves adding or subtracting the velocities of two objects moving relative to each other.
Relative intensity is measured in units abbreviated as?
Relative intensity is measured in decibels and is abbreviated dB.

What will be the relative velocity if two electrons approach each other?
The relative velocity of two electrons approaching each other would be the sum of their individual velocities. Given that both electrons have the same charge and mass, their velocities would be equal in magnitude but opposite in direction. This would result in a combined relative velocity of zero when they meet.
Relative humidity can be measured with a(an)?
hygrometer

What name for Mechanical models of solar system in which planets can be moved at their relative velocities?
Orreries or planetariums are mechanical models of the solar system that can simulate the movement of planets relative to each other at their actual velocities. These models are often used to study and visualize the dynamics of the solar system.
How are the Value of currencies around the world fixed?
It's unofficial, but most of the world's currencies are measured relative to the dollar.
What does your value of relative error mean?
The relative error measurements indicates the quality of a measurement relative to the quantity of the object being measured. To derive the relative error, divide the absolute error by the value of the object being measured.
From were is elevation measured?
Relative to Sea Level.
Which properties are measured relative to time?
frequency
What is the relative amount of kinetic energy?
Kinetic energy is proportional to the square of an object's velocity, so the relative amount of kinetic energy depends on the velocities of the objects in question. If one object is moving faster than another, it will have more kinetic energy. The ratio of their kinetic energies will be the square of the ratio of their velocities.
