Because it is not a good conductor of heat. so the answer is D.
F(in) x d(in)= F(out)x d(out)
A machine has a mechanical advantage of 5.
F(out )= 5xF(in)300 newtons
F(in) = 300 N
F(out)= 5xF(in) = 5x300 N
= 1500 N
Work in = Work out = 3000 N x m3000
N x m = F_in x d_ind_in = 3000 Nxm / F_in = 3000 N x m / 300 N = 10 m3000 Nxm = F_out x d_out d_out = 3000 Nx m / F_out = 3000 N x m / 1500 N = 2 m
Based on the options given, the answer is two waves subtract from each other. Destructive interference happens when two waves meet each other however with different frequencies cancel each other out.

Both the employment rate and labor force participation rate would be higher
