A good baseball pitcher can throw a baseball toward home plate at 86 mi/h with a spin of 1530 rev/min. How many revolutions does the baseball make on its way to home plate

12.1 rev

Explanation:

The question seems incomplete. So for simplicity , we assume that the 60 ft trajectory is a straight line.

First, find the time it takes to get the baseball to homeplate:

t = S / V,

where S is the distance traveled

V is the velocity.

t = 60 ft / 85 mi/h

But 1 Mile = 5280 Feet

Therefore

t= 60 / (86 * 5280) =0.0001321 hours

Coverted to minutes

t=hours×60min

= 0.007928 min.

Second, to calculate the number of revolutions made:

N = t × n

t is the time in minutes

n is the number of spin/min

= 0.007928 × 1530

= 12.1300 = approx. 12.1 revolutions.

12.1 revolutions.

recent improvements in technology/telecommunication/internet have increased the pace of globalization.

explanation:

recent improvements in technology have enhanced the pace of globalization. it is not difficult to recognize that technology has created the human race one big issue. there are several aspects to technology but they all serve to meet us the further. i can beat and be friends with a fellow, thousands of miles away. technology has also bridged the knowledge gap and has presented for the ready transfer of ideas and values.

answer; all of the answers are correct;
