Question

ous fluid flowing from 22 A horizontal pipe nar orizontal pipe narrows from a diameter of 10 to 5 cm. For a nonviscous fluid flowin the larger diameter to the smaller, A) the velocity and pressure both increase. the velocity increases and the pressure decreases. c) the velocity decreases and the pressure increases. D) the velocity and pressure both decrease. - either the velocity or the pressure changes but not both. 23 A particle moving with a simple har e moving with a simple harmonic motion has its maximum displacement of +18 cm at • The frequency of the motion is 10 - At a time t=0.65 s, the position of the particle is A) +18 cm B) zero C) -13 cm D) -18 cm E) +7.3 cm 24 A particle moving with a simple harmo moving with a simple harmonic motion has its maximum displacement of +18 cm at · The frequency of the motion is 10 -1. At a time t = 0.65 s, the position of the particle is A) +18 cm B) zero C) -13 cm D) -18 cm E) +7.3 cm 25 A particle is oscillating with simple harmonic motion. The frequency of the motion is 10 Hz and the amplitude of the motion is 5.0 cm. As the particle passes its central equilibrium position, the acceleration of the particle is A) 100 cm/s? D) zero B) 1.6 x 10 cm/s? E) 3.2 x 10 cm/s c) 4 x 10 cm/s?
