which of the following statment is true
a, a scalar is the one that is conserved in a process.
b, a scalar is the one that can never take negative values.
c,a scalar is the one that does not vary one point to another in space.
d, scalar has the same value for observers with different orientation of the axis
Answers
Answer:
Explanation:
I think option b is correct becoz scalar quantities dont need any direction to be explained..positive nd negative values are assaigned to physical quantities due to their respective direction..negative means opposite direction so scalar dont need it..hope it helps :)
Answer:
(a) False, because several scalar quantities do not remain conserve in a process. For example, energy being a scalar quantity is not conserved in an inelastic collision.
(b) False, because few scalar quantities can take negative values. For example, temperature being a scalar quantity can take negative values such as -10°C, -33°C etc.
(c) False, because several scalar quantities have dimensions. For example, mass, density, speed and pressure etc. all have dimensions.
(d) False, because few scalar quantities vary from one point to another point in space. For example, density, temperature, charge density etc. vary from one point to another point in space.
(e) True, as orientation of axes does not change the value of a scalar quantity. For example, mass, density etc. are independent of the orientation of axes.
