What else can I help you with?
Will the value of a vector quantity changed if the reference axes are changed?
No, the value of a vector quantity will remain unchanged even if the reference axes are changed. The vector will have the same magnitude and direction regardless of the orientation of the axes.
Is a vector necessarily changed if it is rotated through a angle?
No, a vector's magnitude and direction can remain the same if it is rotated through an angle, as long as the rotation occurs around an axis that is parallel to the vector. The vector is considered unchanged in this scenario.
Does velocity stay the same when speed and direction stay the same?
Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.
Is vector necessarily changed if it is rotated through an angle?
No, a vector is not necessarily changed just by being rotated through an angle. The magnitude and direction of the vector may remain the same even after rotation.
If you move an object from the base of a mountain to the top of the mountain what remains unchanged?
The mass of the object remains unchanged, as it depends only on the amount of matter in the object.
Will the value of a vector quantity changed if the reference axes are changed?
No, the value of a vector quantity will remain unchanged even if the reference axes are changed. The vector will have the same magnitude and direction regardless of the orientation of the axes.

When a gas or liquid is heated then its mass is?
The mass remain unchanged.
When sound wave refracted from air to water what will remain unchanged?
The frequency of the sound wave will remain unchanged when it refracts from air to water.
Does velocity stay the same when speed and direction stay the same?
Yes, velocity remains the same when both speed and direction remain constant. Velocity is a vector quantity that includes both speed and direction, so as long as both are unchanged, the velocity will remain constant.
How many unchanges atoms would remain after 3 half lives if the initial sample had 600 unchanged atoms?
After 3 half-lives, half of the original sample would remain unchanged. After the 1st half-life: 300 unchanged atoms. After the 2nd half-life: 150 unchanged atoms. After the 3rd half-life: 75 unchanged atoms would remain.
Do enzymes get used up in a reaction, or do they remain unchanged and available to catalyze multiple reactions?
Enzymes remain unchanged and available to catalyze multiple reactions. They are not used up in a reaction.
Does temperature remain unchanged during vaporisation of a liquid?
yes
What colour do NaCl impart on heating?
The color remain unchanged.
What will happen if there is no physical and chemical change?
The system remain unchanged.
How did the south remain unchanged after the civil war?
the south can be racist.
When water evaporates does its mass increase?
The mass remain unchanged.
