Julian tests four springs and records the results in the table.

a 3 column table with 4 rows. the first column is labeled spring with entries w, x, y, z. the second column is labeled force applied in newtons with entries 20, 60, 40, 50. the last column is labeled displacement in meters with entries 0.5, 0.3, 0.4, 0.1.

which lists the springs in order of increasing spring constant?

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?

When you jump from an elevated position you usually bend your knees upon reaching the ground. by doing this, you make the time of the impact about 10 times as great as for a stiff-legged landing. in this way the average force your body experiences is a) less than 1/10 as great. b) more than 1/10 as great. c) about 1/10 as great.d) about 10 times as great.

In an experiment, how can i change human errors? be specific.
