The main reason why bells are made up of metals instead of wood is because metal is much more dense than wood, meaning that it resonates at much stronger frequencies. Wood has far too much air in it to make loud noises when struck.
Answer:
λ = 6.602 x 10^(-7) m
Explanation:
In a double-slit interference experiment, the distance y of the maximum of order m from the center of the observed interference pattern on the screen is given as ;
y = mλD/d
Where;
D is the distance of the screen from the slits = 6.2 m
d is the distance between the two slits = 0.046 mm = 0.046 x 10^(-3) m
The fringes on the screen are 8.9 cm = 0.089 m apart from each other, this means that the first maximum (m=1) is located at y = 0.089 m from the center of the pattern.
Therefore, from the previous formula we can find the wavelength of the light:
y = mλD/d
So, λ = dy/mD
Thus,
λ = (0.046 x 10^(-3) x 0.089)/(1 x 6.2)
λ = 6.602 x 10^(-7) m

The weight of the load is (mass) x (gravity).
The work done to lift it is (weight) x (distance) = (mass) x (gravity) x (distance)
The power is (work)/(time) =
(mass) x (gravity) x (distance) / (time) =
(500 kg) x (9.8 m/s²) x (12 m) / (1 sec) =
(500 x 9.8 x 12 / 1) (kg-m / sec²) (m) / (sec) =
(500 x 9.8 x 12 / 1) newton - meter / sec =
(500 x 9.8 x 12 / 1) joule / sec =
58,800 watts
= <em>58.8 kW</em>
= about 78.8 horsepower
