Answer:
W = 20 J
Explanation:
Given that,
The mass of a loaded sack, m = 1000 g = 1 kg
It falls down from the floor of a lorry 200 cm high, h = 2 m
We need to find the work done by the gravity. The work done by an object under the action of gravity is given by :
W = mgh
Substitute all the values,
W = 1 × 10 × 2
= 20 J
Hence, the required work done by gravity is equal to 20 J.
I've had a similar question on an assignment myself, so I'm going to assume it had the same idea.
When you organize them in such a way, the pattern that emerges tells you elements organized by atomic weight have the same number of valence electrons.
Hope this helps!
It should be true: electrons low from negative toward positive to negative toward positive because opposite charges attract each other.
I hope this was correct
