y=\dfrac{2xz}{(z-x)}

Step-by-step explanation:

Given:

\dfrac{1}{x}=\dfrac{2}{y}+\dfrac{1}{z}

\implies \dfrac{2}{y}=\dfrac{1}{x}-\dfrac{1}{z}

\implies \dfrac{2}{y}=\dfrac{z-x}{xz}

\implies 2xz=y(z-x)

\implies y=\dfrac{2xz}{(z-x)}

When x = 5 and z = 10:

\implies y=\dfrac{2(5)(10)}{(10-5)}

\implies y=\dfrac{100}{5}

\implies y=20

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Neil will earn interest of 180

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
