Check y 1. In order for the space shuttle Discovery to reach the
minimum altitude required to orbit the Earth, it had to
accelerate from 0 to a velocity of 8000 m/s in 8.5 minutes.
a) How many seconds are there in 8.5 minutes?
b) Calculate the acceleration over this period in
m/s?, assuming it is constant.​

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
