Answer:
Momentum, 
Explanation:
The wave function of a particle is given by :
![y=exp[i(kx-\omega t)]](https://tex.z-dn.net/?f=y%3Dexp%5Bi%28kx-%5Comega%20t%29%5D)
...............(1)
Where
x is the distance travelled
t is the time taken
k is the propagation constant
is the angular frequency
The relation between the momentum and wavelength is given by :
............(2)
From equation (1),
Use above equation in equation (2) as :
Since, 
So, the x-component of the momentum of the particle is 
. Hence, this is the required solution.
Answer:
f =ma = 0.015 * 55 = 0.825 N
so yeah that's ur ans
<u>Answer:</u> The weight of the object is 29.4 N
<u>Explanation:</u>
To calculate the weight of the object, we use the equation:
where,
m = mass of the object = 3 kg
g = acceleration due to gravity = 
Putting values in above equation, we get:
Hence, the weight of the object is 29.4 N
Answer:
Gravity, Friction, Air resistance, magnetism, static electricity
Explanation:
<span>The question is how does an insulator stops the flow of electricity. The correct option is C. This is because insulators are objects whose internal electric charges do not flow freely. They impede the flow of electrons from one atom to another atom, thus restricting the flow of electricity. Insulators are electrically inactive and the are used to stop the flow of electric current. </span>
