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.
What else can I help you with?
What is relative velocity observer moving 3.2meters per second toward object moving toward you at 1.4meters per second?
Ans;- 4.6 meters per second. This assumes they are heading 'Directly' towards each other, and the 'Impact speed' will be the sum of their individual speeds !. But If they are approaching each other on a collision path, but at an angle, then one of the speeds will be vectored, by trigonometry to reduce its approach speed, according to the angle.
What is the apparent velocity of a star relative to another star?
The apparent velocity of a star relative to another star is the speed at which one star appears to move across the sky when observed from the perspective of the other star. This apparent motion is due to the actual motion of both stars through space and can be influenced by factors such as their distance from each other and their individual velocities.
How do you measure the true velocity of an object in the universe if the velocity of all objects in the universe are relative to each other?
If anyone ever referred to the "true" velocity of an object, he mis-spoke. All we can directly measure from the earth is an object's velocity relative to the earth. And when we have measured the velocities of several objects relative to the earth, then we can calculate the velocity of one relative to any of the others. But it's quite correct to observe that there's no such thing as the "true" or "real" velocity of anything, without reference to something else. Except for electromagnetic radiation, including light. That speed is always the same for all observers, no matter who you are, or how you're moving relative to anything else. If I'm moving north at 0.3c, and you're moving south at 0.5c, and Mr. Tompkins is moving west at 0.9c ... all relative to Dallas Texas ... and somebody in Seattle shines spotlights at all three of us, then each of us measures the light passing him at the same speed . . . 'c'. Each of us measures the same number. Makes no sense at all. But it's true.
What is absolute velocity is it the other name for the velocity of a free falling body when the net force of air resistance and gravity is zero?
Absolute velocity refers to the speed and direction of an object relative to a fixed point, regardless of any external factors. In the context of a free falling body with zero net force due to air resistance and gravity, its absolute velocity would be constant and equal to the velocity just before air resistance became negligible.
What are the two major advantages of the scientific approach over the common sense approach?
The two major advantages of the scientific approach over the common sense approach are that it relies on empirical evidence and systematic procedures to test ideas, leading to more reliable and valid results. Additionally, the scientific approach allows for replication of studies by other researchers, increasing the credibility of the findings.
How can one determine the relative velocity between two objects?
To determine the relative velocity between two objects, you can subtract the velocity of one object from the velocity of the other object. This will give you the relative velocity between the two objects.
Can the relative velocity of two bodies be greater than the absolute velocity of either?
Yes it can be!!! If two cars on a straight road head directly toward each other at a speed of 60mph (relative to the road), the velocity of one relative to the other is 120mph. This example arbitrarily uses the road as the reference for each car's speed, but there really is no such thing as "absolute velocity" and both cars would have a velocity of about 1000mph relative to the center of the Earth. According to Einstein's principles of "Relativity" all velocity is relative.
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.
What is relative velocity observer moving 3.2meters per second toward object moving toward you at 1.4meters per second?
Ans;- 4.6 meters per second. This assumes they are heading 'Directly' towards each other, and the 'Impact speed' will be the sum of their individual speeds !. But If they are approaching each other on a collision path, but at an angle, then one of the speeds will be vectored, by trigonometry to reduce its approach speed, according to the angle.
What is the difference between relative velocity and absolute velocity?
One pretty important difference is that relative velocity exists and absolute velocity doesn't. Velocity is always measured and described relative to something. There's no such thing as the "real speed" of a moving object. In fact, according to a scientist who's riding on the object, it's not moving at all. (Close your eyes right now and feel the earth move ?)
Is electron move during the flow of current?
Yes, if there is a current, there will also be a movement of electrons, or other charged particles (but quite often, the charged particles are electrons). In a typical case, the average velocity of the electrons (the drift velocity) is a fraction of a millimeter per second.
Why is velocity a vector quantity and speed is a scalar quantity?
Because it is: * A property of physical objects * Something that can be measured (or calculated from other quantities) Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.
What is Relative charges?
Relative charges refer to the charges of different particles relative to each other. For example, in an atom, protons have a relative charge of +1, electrons have a relative charge of -1, and neutrons have no relative charge (neutral). This allows us to understand how particles interact with each other based on their relative charges.
What is zero velosity?
There is no such thing as zero velocity. Only zero velocity relative to some other thing. And you may have to consider rotational velocities as well.We would only know absolute velocity if we knew the positions and velocities of all the matter in the universe. But ordinary mortal problems do not usually need this, so relative velocity is all we know about.
Can the average velocity of the body be the same as instantaneous velocity?
Yes, the average velocity of the body can be same as the instantaneous velocity at a small time interval.The values of the average and the instantaneous velocities approach each other , as the length of time interval is decreased.
What is the maximum velocity the electrons may have?
Up to 90-plus percent of the speed of light (c). According to current theory, you don't get to go faster than light, and getting to the speed of light is impossible, as mass increases rapidly as you approach c, demanding more and more energy to make up the last few percent of speed.
What is meant by thermal velocity of an electron?
It means that due to the temperature, electrons move back and forth randomly, even if there is no current. A current would imply a systematic movement of electrons, i.e., more electrons moving in one direction than in the other.
