Answer:
there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
10+8 = 18
5+2 = 7
18-7 = 11
a) to the right by 11N.
Answer:
Take north as y and west as -x.
distance=√(x^2+y^2)
displacement= tan theta(tan^-1) (y/x)
answers should be, (9.85m, 66.04°)
R=u^2 sin2x / g
7.8=u^2 sin2*30 /10
u=9.5m/s
