Answer is Weaker. If it is talking about the objects' gravitational forces.
Answer:
the correct one is C
Explanation:
For this exercise we must use the work definition
W = F. s
Where the bold characters indicate vectors and the point is the scalar producer
W = F s cos θ
Where θ is the angles between force and displacement.
Let us support this in our case. The cable creates an upward tension and with the elevator going down the angle between them is 180º so the work of the cable on the elevator is negative.
The evade has a downward force, its weight so the force goes down and the displacement goes down, as both are in the same direction the work is positive
When examining the statements the correct one is C

Answer:
An electron in the third shell has more energy than an electron in the second shell and An electron in the first shell has more energy than an electron in the second shell.
Explanation:
- Calcium has 20 electrons.
- Calcium does not "borrow" electrons. Calcium "donates" 2 electrons.
- Calcium ion (Ca2+) has 18 electron
- Calcium has 2 valence electrons.
- The element Ca, so calcium, has 20 electrons (so it also has 20 protons) this means that it has 2 electrons in its outer orbit, its relative atomic mass is 40.
