Question

The velocity - time graph of a particle is not a straight linr. It's acceleration is
a) negative
b) constant
c) zero
d) variable ​

Answer 1

Answer: d) variable

Explanation: If acceleration would have been constant then the velocity would be increasing in a definite manner, thus producing a straight line going upwards diagonally, but since v-t graph is not a straight line then its acceleration has to be variable i.e. increasing or decreasing.

Answer 2

Answer:

constant

Explanation:

because in the question of bar graph it is mentioned in itwe have to write consent + variable this form constant variable Plus from velocity
