In this graph, what is the displacement of the particle in the last teo seconds? A. 0.2 meters
B. 2 meters
C. 4 meters
D. 6 meters

B

Explanation:

Displacement is a vector quantity. it is the distance covered in a specific direction.

Whereas, Velocity = displacement/time

Make displacement the subject of formula

Displacement = velocity × time

From the graph, velocity is constant which is equal to 1 m/s

Displacement in the last two seconds will be velocity multiply by 2. Since time = 2s. Therefore,

Displacement = 1 × 2 = 2 m

So, the particle displacement in the last two seconds will be 2 metres

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
