Answer:
v = 60 m/s
Explanation:
It is given that,
A wave is represented by the equation :
We need to find the velocity of the wave
The general equation of a wave is given by :
....(1)
Equation (1) can be written as :
...(2)
If we compare equation (1) and (2) we get :
The velocity of a wave is given by :
So, the velocity of the wave is 60 m/s.
Answer:
Explanation:
As we know that
E = 1.8 kV/mm
now we know that electric field between the plated of capacitor is given as
now we will have
now we have
now we have area of the plates of capacitor
Thomson proposed the "plum pudding" model - randomly scattered positive charges and negative charges held in a sphere
Rutherford disagreed with Thomson with his gold foil experiment - proposed that at the centre of an atom was a dense, positive mass and around it were very small negative charges called electrons
Answer:
The acceleration is 3.16x10¹⁷ m/s².
Explanation:
First, we need to find the magnitude of the Coulombs force (F):
<u>Where</u>:
K is the Coulomb constant = 9x10⁹ Nm²/C²
q₁ is the charge = 20x10⁻⁹ C
q₂ is the electron's charge = -1.6x10⁻¹⁹ C
d is the distance = 1.0 cm = 1.0x10⁻² m
Now, we can find the acceleration:
Therefore, the acceleration is 3.16x10¹⁷ m/s².
I hope it helps you!
