Gravity is not unique to the earth, since every object in the universe pulls on every:Read the answer and worked solution →Run the force gatesRead the answer and worked solution →Force bingoRead the answer and worked solution →Two friends push a heavy box from the same side, applying forces of 30 N and 40 N in the same direction. What is the net force on the box?Read the answer and worked solution →A gardener lifting a bucket uses the force produced by her body, called:Read the answer and worked solution →Because muscles must touch the object they move, muscular force is classed as a:Read the answer and worked solution →Based on the tabulated speed-of-sound data for various media, what is the speed of sound in fresh water at 20 degrees Celsius?Read the answer and worked solution →A sound wave has a frequency of 2000 Hz and a wavelength of 0.4 m. What is its speed?Read the answer and worked solution →A tuning fork oscillates at 512 Hz, and sound travels at 345 m/s. How many wave peaks reach the eardrum of a person sitting near the fork in 2 seconds?Read the answer and worked solution →How is the intensity of a sound wave defined?Read the answer and worked solution →A wave carries 10 W of power through an area of 5 square meters. What is the intensity of the wave?Read the answer and worked solution →An 87.0 dB sound has an intensity five times as great as an 80 dB sound. What difference in sound intensity level does a factor of 5 in intensity correspond to?Read the answer and worked solution →What sound intensity level, in decibels, corresponds to the reference intensity I0 = 10^-12 W/m^2, the threshold of human hearing?Read the answer and worked solution →Two sound waves have frequencies of 250 Hz and 280 Hz. What beat frequency do they produce when superimposed?Read the answer and worked solution →A piano tuner compares a piano string with a 256 Hz tuning fork and hears 2 beats per second. What are the possible frequencies of the piano string?Read the answer and worked solution →A closed-pipe resonator has a length of 0.672 m, and the speed of sound is 344 m/s. What is its fundamental frequency?Read the answer and worked solution →Through which state of matter does sound travel fastest?Read the answer and worked solution →A bat produces a sound with a frequency of 17,250 Hz and a wavelength of 0.019 m. What is the speed of this sound?Read the answer and worked solution →Dogs can hear frequencies up to 45 kHz. What is the wavelength of a 45,000 Hz sound wave traveling through air at 0 degrees Celsius?Read the answer and worked solution →Two waves with frequencies f1 and f2 are superimposed. What formula gives the beat frequency f_B?Read the answer and worked solution →

Worked practice questions

Gravity is not unique to the earth, since every object in the universe pulls on every:

  1. Opposing star
  2. Other object
  3. Orbiting moon
  4. Oceanic tide
Show answer and solution

Correct answer: B. Other object

1. Small and large bodies alike take part. 2. The pull is universal, not the earth's alone. 3. So every object pulls on every other object. _Source: syllabus Science Class VIII, Chapter 8, Force and Pressure._
