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

Explanation:

asking the goog might u get an answer

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
