The work done in lifting the block is 3430 J
<h3>Calculating work </h3>
From the question, we are to determine the work done in lifting the block
Using the formula,
Work done = mgh
Where m is the mass
g is the acceleration due to gravity
and h is the height
From the question,
m = 50.0 kg
g = 9.81 m/s²
h = 7.00 m
Putting the parameters into the formula,
Work done = 50.0 ×9.8 × 7.00
Work done = 3430 J
Hence, the work done in lifting the block is 3430 J

Answer:
9m³n⁴
Step-by-step explanation:
18m^5n^4 = 2×3² m^5n^4
45m^3n^6 = 3²×5 m^3n^6
GFC = 3² m³n⁴ = 9m³n⁴
Yes that is maybe cause it is right cause u super smart and u now it girl now go gettim
Answer:
The answer is 2.2
Step-by-step explanation:
To find the missing number, you need to use the opposite operation to find the value of <em>n</em>:
Original equation: 1 / <em>n </em>= 2.2
New equation: 1 * 2.2 = 2.2
