(b) Suppose a horizontal circular loop of wire has a diameter of 7cm and is lowered into sample of crude oil and suppose the additional force that is required to pull the loop out of the oil is 0.08N. Calculate
the surface tension of the sample of crude oil. (2 marks)​

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
