...Assignment no. 4 (due: October 8, 2013, Tuesday, 11.59 PM)
A look into the centripetal acceleration of Earth
Because of the centripetal forces due to Earth’s rotation, a plumb bob might not hang exactly vertical, along a line orthogonal to the Earth surface and directed to the centre of the Earth, as if it was affected only by the force of gravity. Consider a bob located at a latitude of = 35o North with respect to the Equator. You are asked to determine:
a) The centripetal...

Any Single disturbance is called a pulse
A series of pulses is called a wave
In the case of the impatient student, his disturbance was parallel to the direction of the
wave itself. Also called a Longitudinal Wave
WAVES
• Waves can transmit two things
○ Can transmit energy
Ex. Light waves from the sun heat the earth
○ Can transmit information
Ex. Radio wave
When the motion of the...

Abstract
This experiment measures the study of motion by observing the force of gravity acting solely upon an object, and also measures reaction time. If an object is in free fall, the only force acting upon it is gravity. The object used in this experiment was a golf ball that provided some acceleration when dropped. A sensor positioned underneath a table recorded the golf ball’s pattern of motion,...

...designed to reduce the forces on the body if there is a collision. These safety devices are mostly made based on the physics principle of force and momentum, which is
This relationship says that if momentum is transferred over a longer period of time, the force involved is less. If the force of a collision can be reduced, then the chances that someone would get hurt in an accident are lower.4 Since momentum cannot be transformed to another form of energy, it is...

Procedure:
Activity 1:
1. Fill a 400-mL beaker with 300 mL of water and begin heating
2. Mass 8 grams of lauric acid to the nearest 0.01 g, record the mass, and transfer the acid to the culture tube.
3. Clamp the culture tube to a ring stand
4. Heat the lauric acid in the water bath to a minimum of 70 degrees Celsius or until liquefied.
5. Move the clamp/tube assembly out of the water.
6. Place the thermometer in the lauric acid. Stir gently with the thermometer...

...wavelengths) of these radiations can
tell us a lot about the molecule, atom, and nucleus under study.
Since diffraction-grating spectrometers and other types of radiation spectrometers are widely used in all sciences
you should be familiar with the basic physics of such device
What does diffraction look like?
When light diffracts off of the edge of an object, it creates a pattern of light referred to as a
diffraction pattern.
If a monochromatic light source, such as a...

...1. Properties of light
Reflection
The speed of light is measured through the equation: v = λ f. However, it turns out that when light is reflected off a surface its speed stays the same. This was first proven by Sir Isaac Newton. Under the assumption of perfectly elastic collision, the laws of reflection follow from the laws of motion. To demonstrate, consider a particle traveling towards a flat frictionless surface whose horizontal and vertical velocity components are: VX and VY. When the...
