Explanation:
De Broglie discovered that an electron or other mass particles can have a wavelength associated, and that wavelength (λ) is:

with h the Plank's constant (
) and P the momentum of the object that is mass (m) times velocity (v).

Answer:
<h2>
0.147136N/m²</h2>
Explanation:
Pressure is defines as force exerts by a body per its unit area.
Pressure = Force/Area
Given the total force exerted by the gas = 6.05N
Area of the rectangular container = 0.121 m * 0.201 m = 0.024321m²
Pressure of the sample = 6.05/0.02432
Pressure of the sample = 0.147136N/m²
Answer:
Coefficient of friction between the book and floor is 0.582.
Explanation:
Using the velocity formula;
v^2 = 2as
a = v^2/(2s)
a = 1.6^2/(2*0.9)
a = 2.56/1.8
a = 1.42 m/s^2
the force necessary to give the book the acceleration is
F = ma = 3.5*1.42 (m is mass of the book i.e. 3.5 kg)
F = 4.98 N
The difference in the force is the friction force, which is
Ff = 25 - 4.98 = 20 N
Ff = mgμ
where μ is coefficient of friction and g is acceleration due to gravity that is 9.8 m/s^2
μ = Ff/mg
μ = 20/(3.5*9.81)
μ = 0.582
Coefficient of friction between the book and floor is 0.582.
Answer:
m = 45 kg
Explanation:
Given that,
Mass of Jadan, m = 45 kg on Earth
Jupiter has more gravity than the Earth.
Mass of an object is the amount of matter contained inside an object. We need to tell about the mass of Jaden on Jupiter. The mass of the object remains same everywhere.It does not change in any of the location.
Hence, Jaden's mass will be 45 kg on Jupiter.
