Answer:
A = 10 m amplitude
m = 3 kg mass of object
Vm = 5 m/s
w A = Vm where w = omega
w = 2 * pi * f
2 * pi * f 10 = 5
f = 5 / (20 * pi) = .0796 / sec
Answer: a) 112.88 * 10^3 N/C; b) The electric field point outward from the center of the sphere.
Explanation: In order to solve this problem we have to use the gaussian law so we use a gaussian surface at r=0.965 m and the electric flux is equal to Q inside/εo
E* 4*π*r^2= Q inside/εo
E= k*Q inside/r^2= 9*10^9*(6.53+5.15)μC/(0.965)^2=122.88 * 10 ^3 N/C
Using land according to its capability. protect the soil surface with some form of cover. control runoff before it develops into an erosive force
That waves travel faster than the wave lenght!
