impulse= force ×time
1) 0.1×200=20
2) 5×5.5=27.5
3) 10×2=20
4) 25×0.8==20
so the answers are 1,3,4
<h3>hope it helped :-)</h3>
I think the answer is C) 1/8, I’m sorry if it’s wrong
The answer is (B.) lattice energy
The d-block elements are found ingroups 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 of the periodic table; d-block elements are also known as thetransition metals. The d orbital is filled with the electronic shell “n-1.”
If the element is neutral, this means that there are precisely Z electrons, and the overall electronic charge is −Z . And thus the net ELECTRIC charge of the ATOM is Z+(−Z)=0 , i.e. zero
