What is the kinetic energy of the mass at point P, halfway between the equilibrium point and the amplitude? P Equilibrium A. 50 J B. 200 J C. 75 J D. 100 J E. 25 J When a weight Wis hanging from a light vertical string, the speed of pulses on the string is v. If a second weight Wis added without stretching the string, the speed of pulses on this string will now be A. 4v B. 2v OC. v/v2 D. V2v E. Reset Selection 27- Question 6 of 7 2 Point Which of the following is a FALSE statement? A. The speed of a wave and the speed of the vibrating particles that constitute the wave are different entities. B. In a transverse wave the particle motion is perpendicular to the velocity vector of the wave. C. Waves transport energy and matter from one region to another. 27- Awavimbiab nantialan A spring-cart system on a frictionless surface and a simple pendulum both have the same period near Earth's surface. What happens to the period of each motion when both systems are in orbit inside the International Space Station? (Assume zero gravity in the International space Station). Your answer should not be more than 70 words. Please be concise. L A pendulum of length L swings with an amplitude and a frequency fas depicted above. If the amplitude is increased, then.. (Note that for both cases the amplitude o is small) A. the frequency will increase. B. the frequency will decrease C. the period will increase. D. the period will not change. E. the period will decrease. 26€ A mass at the end of an ideal spring vibrates with period T. If you double the mass, how must you change the force constant of the spring to achieve a period of 2T ? A. Decrease it by a factor of 2. B. Increase it by a factor of 0.2 c. Decrease it by a factor of 0.2. D. Increase it by a factor of 2. E. Decrease it by a factor of 20 274 The maximum velocity of a particle executing simple harmonic motion with amplitude 7.0 mm is 4.4 m/s. The period of oscillation is? A. 100 s B. 0.5 s C. 10 s D. 0.01 s E. 0.1 s

Answer 1

between the equillibrium and amplitude energy 5oJ kintetic since at extremum it is ou 2 ) VE 시 u= to mass it W keeping per unit length T same to 2 W and u is changed from > yo v becomes Cophi4n. O r2 3) transport Waves one is energy and not matter from another so option ce region to correct.
