​

Answer 1

$\orange{ \dag} \widetilde{ \huge{ \bf{ \pmb{ \frak{ \color{hotpink}{ \underline{ \underline{ \colorbox{lavender}{ \color{darkviolet}{Añśwēr}}}}}}}}}} \orange{ \dag}$

Correct statement will be: “The car rounded the curve at a constant speed of 70 km/h.”

Because velocity denotes speed (magnitude) with direction. And, we know that in circular motion, the direction changes, as shown below:

So velocity will not remain constant but speed will remain constant.
