Given E=2050 N/C
charge of an electron = 1.6×10^-19 C
USING E = F/Q , electric field = force ÷ charge
2050 = F ÷ (1.6×10^-19)....
make F subject of formula and get the answer
shm
displacement is A*sin 2pi f t
vel =( A*2*pi*f*)*cos 2 pi f t
accn =-( A*2*pi*f*)^2*sin 2 pi f t
accn = (0.01*2*3*5)
accn = (0.01x30)^2=9
I'm guessing <span>10.6% based on the following information:
</span>
Mass soln = <span>density×volume=1.06×875=927.5<span>g
</span></span><span><span>M<span>NaCl/</span></span><span>Msoln</span></span>×100=<span>%M
which means this:
</span>
%M=98.6927.5×100=10.6
