1. The density of a substance can be found by : Density = Mass /(Volume)". The density
of water is 1.0 gram/cm'. If a container in the shape of a cube is filled with 1 m of
water, what would be the mass of the water in kilograms?. (Hint: Convert cubic
centimeters to cubic meters and grams to kilograms). 1 kilogram=1000 grams, and 100
cm= 1 m.
2. A rectangular container measuring 20 cm x 20 cm x 30 cm is filled with water. What is
the mass of this volume of water in kilograms and in grams? (Use the information given
in question 1.)
3. Use the following formula for converting Farenheit to Celsius Scale of temperature to
answer the question that follows.
T'F = (9/5) Tc + 32
The normal human body temperature is usually taken as 98. 6"F. What is the equivalent
temperature on the Celsius scale?
4. Consider a sound wave with a speed of 344 m/s and frequencies of (a)( 20 Hz and (b)
20kHz. Find the wavelength of each sound wave. (Hint: v = 1/T = af )
5. The speed of radio waves is same as the speed of the light in vacuum, which is
3X10 m/s. What is the speed of radio waves produced by a station with an assigned
frequency of 600 kHz?
6. The speed of sound in air at 20°C is 344 m/s. What is the wavelength of a sound wave in
air at 20°C with a frequency of 22 MHz.? (1 Mega=10° ).
7. What is the period of wave motion for a wave with a frequency of 5.0 kHz?
8. Waves moving on a lake have a speed of 2 m/s and a distance of 1.5 m between
adjacent crests. (a) What is the frequency of the waves? (b) Find the period of the wave
motion.
9. Compute the wavelength of an X-ray with a frequency of 10"Hz. Use the speed of light.
10. During a thunderstorm, 4.5 second elapses between observing a lightning flash and
hearing the resulting thunder. Approximately, how far away in kilometers and miles was
the lightning flash? (1 km =0.62 miles)
