We are given with two measurements of the arm and an input weight. To answer this problem,we need to balance the forces and use the lengths of the arms.
209 N * 8 m = x * 1.5 m
x = 1114.67 N

it takes 1114.67 N to lift the input weight

Electrons with energy of 25 eV have a wavelength of ~0.25 nm. If we send these electrons through the same two slits (d = 0.16 mm

kupik [55]

Answer:

The spacing is 5.15 μm.

Explanation:

Given that,

Electron with energy = 25 eV

Wave length = 0.25 nm

Separation d= 0.16 mm

Distance D=3.3 m

We need to calculate the spacing

Using formula of width

$\beta=\dfrac{\lambda D}{d}$

Put the value into the formula

$\beta=\dfrac{0.25\times10^{-9}\times3.3}{0.16\times10^{-3}}$

$\beta=5.15\times10^{-6}\ m$

$\beta=5.15\ \mu m$

Hence, The spacing is 5.15 μm.

Fitness can be achieved only through

Iteru [2.4K]

Fitness is more accurately described as habit, so it is achieved only through A. frequency<span>. In order to achieve results in fitness, one must be consistent with exercise and nutrition. Not only is this the means to achieving fitness, this is also the way that fitness is maintained. </span>
