Volume of an irregular object is measured by using a mmeasuring cylinder​

true

Explanation:

take water in a measuring cylinder then put that object whatever the inch will come that's it's volume

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
