If the pressure of a gas is increased then what happen to mean free path

Answer»

end here is ur ANSWER ✨The pressure of a gas increases then the mean free path DECREASES. because, as gas DENSITY increases the molecules became closer to each other. Therefore, they are more LIKELY to run into each other, so the mean free path decreases. increasing the number of molecules or DECREASING the volume causes density to increase. so, the mean free path decreases.✨ Hope it helps you ✨❤️ Thank you ❤️

How to get distance travelled by object from its speed time graph

Answer»

get the distance traveled by object from its speed by speed time graph ?Answer :-We can calculate the distance traveled by calculating the area under the graph.We have to count the number of squares for the area.If the line is a curve , then we NEED to calculate the area by calculus.Otherwise if the LINES are STRAIGHT , we can find the area by using simple geometry itself.Also we can calculate the ACCELERATION by calculating the slope of the graph.I know only this much Hope it HELPS !___________________________________________________________________

Spring balance is of least count 2 GF its pointer is at three division below the zero mark when no weight is suspended from it but when a stone is suspended from it the reading becomes 48 GF . When the same suspended force is immersed in water the reading become 40 GF calculate the actual weight of stone in air and the Apparent loss and weight of the stone when immersed in water

Answer»

ount 2gf means each division 2gfGiven 3division below zero means 6gf(spring balance below means positive)When stone suspended the READING comes to 48gf but 6gf is ALREADY extra so actual wt of stone 48-6=42gfAnd apparent loss =48-40=8gfI don't ASSURE my ANSWER
