H+ ions increase in concentration at lower ph values. what is the concentration of h+ ions at a ph = 2?
calculate how many more h+ ions there are in a solution
mol/l
at a ph = 2 than in a solution at a ph = 6. find the
concentration of h+ ions at a ph = 2 and at a ph = 6 in
andata ph-6 in what is the concentration of h+ ions at a ph = 6?
table b. then divide the concentration of h+ ions at a
mol/l
ph = 2 by the of h+ ions at a ph = 6. record your answer how many more htions are there in a solution at a
in table c.
ph = 2 than in a solution at a ph = 6?

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.

Which of these metals are magnetic?

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
