When you start your computer, the hard disk begins to spin. It takes 5.00 seconds of constant angular acceleration to reach full speed, at which time the computer can begin to access it. If you wanted the disk drive to reach full speed in only 2.00 seconds, how much more torque would the disk drive’s motor have to exert on it during the starting process (Find the ratio of the two torques)?

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures

365.25 earth days are in the year of a light year
