Answer:
electron λ = 12.5 nm
, bullet λ = 1.11 10⁻³³ m and golf ball λ = 4.7 10⁻³⁴ m
Explanation:
The Broglie wave duality principle states that all matter has wave and particle properties, it is expressed by the equation
p = h / λ
Where lam is called broglie wavelength
Let's use the definition of momentum
p = mv
Let's calculate the wavelengths
-Electron
mv = h /λ
λ = h / mv
λ = 6.63 10⁻³⁴ / (9.1 10⁻³¹ 5.81 10⁶)
λ = 1.25 10⁻¹⁰ m
λ = 12.5 nm
This is the X-ray region
-bullet
λ = 6.63 10⁻³⁴ / (1.90 10⁻³ 313)
λ = 1.11 10⁻³³ m
It is too small, only particle characteristics are observed
-Golf ball
λ = 6.63 10⁻³⁴ / (4.50 10⁻² 31.3)
λ = 4.7 10⁻³⁴ m
Too small, only particle characteristics are visible
Answer:
Colour
Malleability
Ductility
Lustre
Conductivity
Softness
Explanation:
Color : Silver-White.
Malleability : Capable of being shaped or bent.
Ductility : Easily pulled or stretched into a thin wire.
Luster : Has a shine or glow.
Conductivity : Good transmission of heat or electricity.
Softness : Soft enough to be cut with a knife.
<span>System B: The amorphous silicon solar modules have an efficiency of 6%. The dimensions of the solar modules amount to 0.5m by 1.0m. The output of each module is 30 Wp. The modules cost 20€ each. The advanage of the amorphous silicon solar modules is that they perform better on cloudy days in which there is no direct sunlight. Installed in the Netherlands, this system gives, on a yearly basis, 10% more output per installed Wp than the multicrystalline silicon modules. </span>
<span>System A: The efficiency of the multicrystalline silicon module amounts to 15%. The dimensions of the solar module are 0.5m by 1.0m. Each module has 75 Wp output. The modules cost 60€ each.

Potential energy = mass x g x height.
height = potential energy/mass x g
acceleration due to gravity on earth is 9.8 m/s
filling in your variables gives us:
490/50 x 9.8 = 1 meter
