Answer:
The frequency does not depend on the amplitude for any (ideal) mechanical or electromagnetic waves.
In electromagnetism we have that the relation is:
Velocity = wavelenght*frequency.
So the amplitude of the wave does not have any effect here.
For a mechanical system like an harmonic oscillator (that can be used to describe almost any oscillating system), we have that the frequency is:
f = (1/2*pi)*√(k/m)
Where m is the mass and k is the constant of the spring, again, you can see that the frequency only depends on the physical properties of the system, and no in how much you displace it from the equilibrium position.
This happens because as more you displace the mass from the equilibrium position, more will be the force acting on the mass, so while the "path" that the mass has to travel is bigger, the mas moves faster, so the frequency remains unaffected.
Answer:150N
Explanation:
Total mass=mass of skate board + mass of rider
Total mass(m)=46kg + 4kg
Total mass(m)=50kg
Acceleration(a)=3m/s^2
Force(f)=mass x acceleration
Force=50 x 3
Force=150N

Answer:
The average velocity is 8 unit per sec
Explanation:
Given as :
The Distance x = 20 - 4t² unit
Change in time Δt = ( 2 - 0 ) s = 2 s
Let the velocity = V unit/s
∴ V = 
Or, V = - 8t unit/s
Now velocity at t = 0
V1 = - 8 × 0 = 0 unit/s
And velocity at t = 2 sec
V2 = - 8 × 2 = - 16
So, Average velocity = 
= 
= -8
Or, 
= 8 unit/sec
Hence The average velocity is 8 unit per sec Answer
<span>.when 2 elements are connected in a parallel connection the voltage across them must be same
</span><span>when 2 voltage sources are connected they must have same potential difference across them which is not possible unless they are of same value and in the other case(different value sources) it is same as the greater valued voltage source since it overtakes the other one
</span>
Which means that there is no use in connecting both of them in parallel
hope this helps
