As a certain object falls, its position s (in meters) above ground after t seconds is given by s(t)=20-5t^2. whats the average velocity of the object on the interval from t=1 to the time .5 seconds later? ? from t=1 to the time .1 seconds later?

Astudent is working in the lab to determine how time affect impulse the student keeps the force the same in each row but changes impact the time some data is shown witch trial has the greatest a student is working in the lab to determine how time affect impulse the student keeps the fours the same in each row but change is the impact time some data shown witch trial has the greatest impulse

Could someone . i have tried to solve myself but my calculation is off

Students in an introductory physics lab are performing an experiment with a parallel-plate capacitor made of two circular aluminum plates, each 11 cm in diameter, separated by 1.0 cm. how much charge can be added to each of the plates before a spark jumps between the two plates? for such flat electrodes, assume that value of 3×106n/c of the field causes a spark.
