A kangaroo jumps up with an initial velocity of 36 feet per second from the ground (assume its
starting height is O feet). Use the vertical motion
model, h = –16t2 + vt +s, where v is the initial
velocity in feet per second and s is the height in
feet, to calculate the amount of time the kangaroo
is in the air before it hits the ground again. Round
your answer to the nearest tenth if necessary.
Time in air:seconds

What is the difference between electrically neutral objects and electrically charged objects

Agymnast dismounts off the uneven bars in a tuck position with a radius of 0.3m (assume she is a solid sphere) and an angular velocity of 2rev/s. during the dismount she stretches out into the straight position, with a length of 1.5m, (assume she is a uniform rod through the center) for her landing. the gymnast has a mass of 50kg. what is her angular velocity in the straight position?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
