Answer:
Step-by-step explanation:
Work can be found by multiplying the force by the distance traveled in the direction of the force.
The force is 45 Newtons.
The distance traveled is 1 meter.
Substitute the values into the formula.
Multiply.
1 Newton meter is equal to 1 Joules.
Therefore our answer of 45 Newton meters is equal to 45 Joules.
The work done is <u>45 Joules.</u>
Answer:
20 liters of the 40% solution
60-20=40 liters of the 70% solution
Step-by-step explanation:
40%x+70%(60-x)=60%(60)
0.4x+0.7(60-x)=0.6(60)
0.4x+42-0.7x=36
-0.3x+42=36
-0.3x=-42+36
-0.3x=-6
0.3x=6
3x=60
x=60/3
x=20 liters of the 40% solution
60-20=40 liters of the 70% solution
check: 0.4*20=8
0.7*40=28
8+28=36 and 0.6*60=36 also
Answer:
-60
Step-by-step explanation:
If the worker is descending, he is going down. The change in his position could be marked on a graph by translating the original point down by 60 units. Aka -60 units.
