Find the true statement. use the underlined word to determine whether the statement is true or false. question 3 options: electromagnetic waves are mechanical because they require a medium to travel. electromagnetic waves are transverse because they have electric and magnetic fields that move perpendicular to the direction of energy transfer. the speed of an electromagnetic wave depends on the frequency of the wave. gamma rays are faster than radio waves. as the frequency of an em wave increases, so does the wavelength. they are directly related.

The discovery that the universe appears to be expanding led to a widely accepted theory called a.) the big bang theory b.) the doppler effect c.) hubble’s law d.) solar nebular theory e.) the seyfert theory

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
