B. In a hurricane, the air is blowing over the roof of the house at a speed of 110kmh-1. The density of air is 1.2 kgm-3. a) What is the pressure difference inside and outside the house that tend to lift the roof? (2 marks b) What would be the lifting force on that roof of area 95 m2? (2 marks)​

The diagram shows a person using a piece of gym equipment to lift weight which best describe the body in terms of simple machine

Did the proton move into a region of higher potential or lower potential? did the proton move into a region of higher potential or lower potential? because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a negative charge and it accelerates as it travels, it must be moving from a region of lower potential to a region of higher potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of higher potential to a region of lower potential.because the proton is a positive charge and it slows down as it travels, it must be moving from a region of lower potential to a region of higher potential.request answerpart bwhat was the potential difference that stopped the proton? express your answer with the appropriate units.î”v î” v = nothingnothingrequest answerpart cwhat was the initial kinetic energy of the proton, in electron volts? express your answer in electron volts.ki k i = nothing ev request answerprovide feedback
