Answer:
2/3
Step-by-step explanation:
The work done on the box is ...
Fd = (60 N)(10 m) = 600 N·m = 600 J
The amount of energy the box has as a result is ...
KE = 1/2mv² = (1/2)(8 kg)(10 m/s)² = 400 kg·m²/s² = 400 J
The ratio of box energy to energy input is ...
η = (400 J)/(600 J) = 2/3 . . . ≈ 66.7%
Answer:
Proprortional Value is equal to 2/3 or 2:3
Step-by-step explanation:
4/6=2/3
6/9=2/3
8/12=2/3
10/15=2/3
14/21=2/3
11/7 times 3.
Let’s make 3 as 3/1 because it’s the same thing.
It’s the same thing because 3 divided by 1 is also 3.
11 x 3 = 33
— —
7 x 1 =7
This equals 33/7.
So the answer is 33/7!
