Use the equation for work (W = Fd) to calculate the work done by each robot. Remember: F(force)= N(newtons)
d(distance)= m(meters) Your answer for work is in Joules (J)

1. Robot 1 applies 20 N of force to lift 2 building blocks 3 m.
J
2. Robot 2 applies 30 N of force to lift 3 building blocks 3 m.
J
3. Robot 3 applies 10 N of force to lift 1 building block 2 m.
J
4. Robot 4 applies 30 N of force to lift 3 building blocks 2 m.
J

Step-by-step explanation:

lololololol

i dont know

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
