Answer:
(b) The electrons, because they have the smaller momentum and, hence, the larger de Broglie wavelength
Explanation:
de Broglie wavelength λ = h / m v
Since both electrons and protons have same velocity , momentum mv will be less for electrons because mass of electron is less .
for electron , momentum is less so . Therefore de Broglie wavelength λ will be more for electrons .
Amount of diffraction that is angle of diffraction is proportional to λ
Therefore electrons having greater de Broglie wavelength will show greater diffraction.
Answer:
Explanation:
Required
The units of A and B
From the question, we understand that:
This implies that each of 
and 
will have the same unit as 
So, we have:
The unit of t is (s); So, the expression becomes
Divide both sides by 
Answer: An aquifer is a body of saturated rock through which water can easily move. Aquifers must be both permeable and porous and include such rock types as a sandstone.
Explanation: However, if these rocks are highly fractured, they make good aquifers.
Constant velocity means the netto force = 0, therefore F(gravity) = F(astronaut).
175N divided by 87,5kg = 2.00kg/N
Answer:
<h2>151.8 N</h2>
Explanation:
The force acting on the blimp can be found by using the formula
<h3>f = p × a</h3>
p is the pressure
a is the area
3000 cm² = 0.3 m²
From the question we have
f = 506 × 0.3
We have the final answer as
<h3>151.8 N</h3>
Hope this helps you
