    Scalars
In summary, during a conversation about scalar quantities, the participants discussed various options for defining a scalar quantity. While some options were initially thought to be true, it was ultimately concluded that all options were false, except for the option that states a scalar quantity has the same value for observers with different orientations of axes.

Kindly throw me light on this!
Q: A scalar quantity is one that:
a) is conserved in a process.
b) can never take negative values
c) Must be dimensionless.
d) Does not vary from one point to another in space.
e) has the same value for observers with different orientations of axes.

I feel, everything is false.
(a) is false because mass is not conserved in nuclear reactions.
(b) is false because work done ( a scalar) can be negative.
(c) is false definitely.
(d) is false because distance varies.
(e) is false because distance depends on the frame of reference chosen, right?

But the question was given as MCQ, without answers, in a text.

One of the options is correct. You are asking one question in your post and you should reexamine that one.

You mean. the last one? oh yes. Sorry. Whatever frame of reference is chosen, distance remains constant. OH yes. Thank you. So, the correct option is answer (e) .

Indeed.
 

Related to Answer Scalar Quantity Q: Is Everything False?

1. What is a scalar quantity?

A scalar quantity is a physical quantity that has only magnitude and no direction. Examples include temperature, mass, and time.

2. What does "everything is false" mean?

"Everything is false" is a statement that implies that all statements or claims are false and cannot be proven true.

3. Can everything really be false?

This is a philosophical question that does not have a definitive answer. Some argue that there must be some truth in order for the statement "everything is false" to exist, while others argue that it is a paradox and cannot be proven either way.

4. How does this relate to science?

In science, we use empirical evidence and experimentation to determine the truth of a statement or claim. The statement "everything is false" goes against this approach, making it difficult to apply to scientific principles.

5. What are the implications of this statement?

The implications of this statement are complex and can vary depending on one's perspective. Some may argue that it challenges the concept of objective truth, while others may see it as an interesting thought experiment.
