Answer:
Step-by-step explanation:
Work is said to be done when a force applied to an object cause the body to move in a specified direction.
Work-done = Force * Distance
Since Force = mass * acceleration due to gravity
Work-done = mass * acceleration due to gravity * distance
Given mass = 1.4kg, distance = 0.7m and g = 9.8m/s²
Workdone in lifting the book off the floor = 1.4*0.7*9.8
Workdone = 9.604Joules
- Similarly, work done in lifting a 21-lb weight book 6 ft off the ground is expressed using the same formula as above;
Given mass = 21-lb, g = 32ft/s² and distance = 6ft
Workdone = 21 * 32 * 6
Workdone = 4,032 lb-ft²/s²
Hence, work-done in lifting a 21-lb weight book 6 ft off the ground is 4,032 lb-ft²/s²
Answer:No it is not proportional
Step-by-step explanation:
The reason non proportional is not proportional is bc it's not proportional.
Answer:
-3x-6
Step-by-step explanation:
distribute the -3

Volume = length x width x height
Thus, you need to find the cubic root of 500....the number that when multiplied by itself three times = 500,
There are different ways to write this.
![\sqrt[3]{500}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B500%7D%20)
=
![\sqrt[3]{125 * 4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B125%20%2A%204%7D%20)
= 5
![\sqrt[3]{4}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B4%7D%20)
You can also show it as a decimal using a calculator = 7.94
