Answer 1

7000degrees/sec

Explanation:

The question is not properly structured. Here is the correct question.

A pitcher's arm rotates at a speed of 7 degrees per millisecond (degrees/ms) . At what speed does the pitcher's arm rotate in degrees/s?

Before we proceed, you must know that we will be applying the following conversion;

1 milliseconds = 10⁻³secs

Given

Speed of pitcher's arm in degree per milliseconds = 7deg/ms

Required

We are to express in degree/sec

Using the conversion formula above;

`7deg/ms = (7^0)/(1millisecs) \\\\converting \ to \ deg/s\\7deg/ms = (7^0)/(1millisecs) * (1)/(10^(-3)s)\\7deg/ms = (7^0)/(10^(-3)s)\\`

`7deg/ms = 7^0 * 1/0.001s\\7deg/ms = 7^0 * 1000/s\\7deg/ms = 7000^0/sec\\`

Hence the value in degree/sec is 7000degrees/sec
