When a straw with liquid is covered by a finger and raised, the liquid does not leak from the straw. Explain this using ideas of pressure exerted by particles.

Take your finger away from the straw and the downward force of the air pressure on the liquid will be the same as the upward force. These two effects cancel each other out leaving gravity as the dominant force causing the suspended liquid to drop out the bottom.

lol I don't know think u could help me with my mathematics

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down
