Pick out the only vector quantity in the following list:
Temperature, pressure, impulse, time, power, total path length, energy, gravitational potential, coefficient of friction, charge.
Impulse : Impulse is given by the product of force and time. Since force is a vector quantity, its product with time (a scalar quantity) gives a vector quantity.
Unit vector does not have any .......
What is vector ? How it can be represented ?
Position of a particle in a rectangular-co-ordinate system is $(3, 2, 5)$. Then its position vector will be
A scalar quantity is one that
If a unit vector is represented by $0.5\hat i + 0.8\hat j + c\hat k$, then the value of ‘$c$’ is
