A student pushes a box across the floor using 8w of power in 7 seconds how much work does the student do

Workdone = 56 Joules

Step-by-step explanation:

Given the following data;

Power = 8 watt

Time = 7 seconds

To find the workdone;

The workdone by an object or body is given by the formula;

Workdone = power * time

Workdone = 8 * 7

Workdone = 56 Joules.

452,489 to the nearest thousand is 452,000

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
