Answer:
Part A:
The proton has a smaller wavelength than the electron.
<
Part B:
The proton has a smaller wavelength than the electron.
<
Explanation:
The wavelength of each particle can be determined by means of the De Broglie equation.
(1)
Where h is the Planck's constant and p is the momentum.
(2)
Part A
Case for the electron:

But 


Case for the proton:


Hence, the proton has a smaller wavelength than the electron.
<em>Part B </em>
For part b, the wavelength of the electron and proton for that energy will be determined.
First, it is necessary to find the velocity associated to that kinetic energy:


(3)
Case for the electron:

but


Then, equation 2 can be used:

Case for the proton :

But 


Then, equation 2 can be used:

Hence, the proton has a smaller wavelength than the electron.
Answer:
The mass of the box:
m = 60 kg
Explanation:
Given:
F = 150 N
g = 10 m/s²
_________
m - ?
Coefficient of friction wood on wood:
μ = 0.25
Friction force:
F₁ = μ*m*g
Newton's Third Law:
F = F₁
F = μ*m*g
The mass of the box:
m = F / ( μ*g) = 150 / (0.25*10) = 60 kg
Answer:
D. provide the most compelling evidence of cause-and-effect relationships.
Explanation:
Explanation:
The newton's laws of motion are:
First law:
"A body will remain in its state of rest or of uniform motion along a path unless it is acted upon by an external force. ".
This is popularly called the law of inertia.
Second law:
"the acceleration of a body is produced by a net force that is inversely proportional to the mass of the body".
Third law:
"action and reaction forces are equal and opposite in direction".

Answer:
An object changes position if it moves relative to a reference point. The change in position is determined by the distance and direction of an object's change in position from the starting point (displacement). Direction • Direction is the line, or path along which something is moving, pointing, or aiming.
