It is a uniform circular motion. So the direction of velocity changes but not the magnitude. Therefore speed in considered constant. Again magnitude of acceleration does not change.
20.
Use thumb rule
21.
(b)

22.
Velocity and acceleration are in the same direction: So speed increases.
23.
Mass, length are scalars. Acceleration is a vector but magnitude of acceleration is a scalar
24.
Unit vector specifies only direction
\(\hat{A}=\frac{\vec{A}}{|\vec{A}|} \)
\(\therefore \hat{i}+\hat{j}=\frac{\hat{l}+\hat{j}}{|\hat{l}+\hat{j}|}
\)
\(\hat{i} \text { and } \hat{j} \text { are orthogonal components of vectors. }\)
