Question

measure the volume of a metallic object from the readings of water level in a measuring cylinder using displacement method.Also calculate the same volume from the dimensions measured using suitable scale.Comment on the accuracies​

Answer 1

Answer:

Given that,

Force F=100dyn

Mass m=5g

Time t=10s

Initial velocity u=0

Now, the acceleration is

F=ma

a=

m

F

a=

5×10

−3

100×10

−5

a=0.20m/s

2

Now, from equation of motion

v=u+at

v=0+0.20×10

v=2m/s

v=200cm/s

Hence, the velocity produced is 200 cm/s
