Answer:
461 m/s
Explanation:
Given the string length of guitar, l = 0.90 m
Frequency , f = 256 Hz
Using frequency, wavelength and velocity relation as
v=f λ
Here λ is wavelength.
Now for guitar string the length must be equal to half of wavelength, so
λ = 2l
Therefor above formula becomes as
v = f×2l
Substituting the given values, we get
v =256×2×0.90
v = 460.8 m/s = 461 m/s
Thus, the wave moving back and forth along the string with velocity 461 m/s.
Answer:
The surface charge density of the sheet is 1547.516 C/m²
Explanation:
Given;
force experienced by the proton, F = 14.0 μN
Electric field near an infinite sheet with surface charge density (σ) is given as;
E = σ/2ε₀
The force of attraction the proton experienced towards the sheet;
F = Eq
F = q(σ/2ε₀) 
where;
q is the charge of the proton
σ is the surface charge density of the sheet
ε₀ is the permittivity of free space
Therefore, the surface charge density of the sheet is 1547.516 C/m²
<span>If you apply 100.0 N of force to lift an object with a single, fixed pulley, then the resistive force is also equivalent to 100 Newtons of force. Since the weight of the object was not mentioned, it is assumed that it has already been taken into account in the 100 N value of force. This follows Newton's law of motion of equal action and reaction.</span>
The first question's answer is :
If, F=ma
Then, 15N= 2.1kg (a)
15/2.1=a
7.14=a
Therefore, acceleration = 7.14m/s^2
sorry I am not sure about the second question :-(
