the bal will not change its velocity.

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

While travelling along a highway a drivers velocity is 9 m/s. In 12 seconds, the car has gone for 108 m.

Explanation:

The car travelling along the highway has a uniform velocity of 9 m/s. therefore to calculate the distance travelled by the car with the uniform velocity in 12 seconds, simple formula of velocity is to be employed.

Thereby, as we know that

$\text {velocity}=\frac{\text {displacement}}{\text {time}}$

The displacement is along the highway with uniform motion, therefore, distance=displacement

Given that,

Velocity = 9 m/s

Time = 12 s

Putting the values in the formula, we get,

$9 = \frac{d}{12}$

$d=12 \times 9=108 \mathrm{m}$

Therefore, the car travels for 108 m in the 12 seconds while travelling along highway with 9 m/s of velocity.
