5.Calculate the wavelength of a 95×106 (Hz) radio wave with amplitude E0=5.42.00 (Volt/m). (A) 4.24 (m) (B) 3.16 (m) (C) 5.12 (m) (D) 2.55 (m)

11. Consider the track shown in Figure 3. The track AB is one quarter of a circle of radius R=3.0(m) and is frictionless. The horizontal track from B to Chas a length of d=4.0(m) and a coefficient of kinetic friction =0.23. The track CD under the spring is frictionless. The track CD forms an angle θ=30° with the horizontal plane. A block with a mass of m=2.2(kg) is released from rest at point A. After sliding m along the track, it compresses the spring by 0.35 (m) and comes to rest at a distance 0.8 (m) from C. Determine the stiffness constant k for the spring. spring. (A) 610 (N/m) (B) 591 (N/m) (C) 554 (N/m) (D) 732 (N/m)

(A) 4.24 (m)
(B) 3.16 (m)
(C) 5.12 (m)
