Cathode-Ray Oscilloscope OBJECTIVE: To learn how to operate a cathode-ray oscilloscope. APPARATUS: Cathode-ray oscilloscope‚ multimeter‚ and oscillator. INTRODUCTION: The cathode-ray oscilloscope (CRO) is a common laboratory instrument that provides accurate time and aplitude measurements of voltage signals over a wide range of frequencies. Its reliability‚ stability‚ and ease of operation make it suitable as a general purpose laboratory instrument. The heart of the CRO is a cathode-ray tube

PRINCIPLE OF CAUSATION Every criminal action can be divided into actus reus‚ mens rea and causation. Actus reus compacts with the ‘guilty act’‚ mens rea with the ‘guilty mind’ and the causation compacts with the consequences of the actus. In crimes‚ which require consequence like murder‚ causation is a essential and imperative element. The absence of causation between the actus and the consequence may render a verdict untenable in spite of the existence of the necessary mens rea and actus reus

1. How do you calibrate an Oscilloscope? In order to calibrate the Oscilloscope‚ we connected the BNC alligator into the channel we wanted to calibrate (Channel 1). We clipped the red probe to the calibration knob‚ and we saw a 2 volt VPP signal. The desired output from the oscilloscope was a 1000 Hz calibration frequency. The 1000 Hz frequency is the standard frequency for most of the oscilloscopes. After we clipped the red probe‚ we saw a square wave signal. The first thing we calibrated was the

vertices as shown in the figure: Sine (sin) Function of an acute angle of a right triangle is equal to the ratio of the length of the opposite leg to the length of the hypotenuse. Cosine (cos) Function of an acute angle of a right triangle is equal to the ratio of the length of the adjacent leg to the length of the hypotenuse. Tangent (tan) Function is equal to the ratio of the length of the opposite leg to the length of the adjacent leg. The reciprocal of the sine function is the Cosecant (csc)

result of a perpendicular with the half-side is the area."[14] Aryabhata discussed the concept of sine in his work by the name of ardha-jya. Literally‚ it means "half-chord". Later in the 12th century‚ when Gherardo of Cremona translated these writings from Arabic into Latin‚ he replaced the Arabic jiab with its Latin counterpart‚ sinus‚ which means "cove" or "bay". And after that‚ the sinus became sine in English.[15] [edit] Indeterminate equations A problem of great interest to Indian mathematicians

Neighbour Principle: You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour- Who‚ then‚ in law‚ is my neighbour? The answer seems to be - persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected when I am directing my mind to the acts or omissions that are called in question Donoghue v Stevenson Neighbour Principle: You must take reasonable

converting the linear motion of a slider into rotational motion or vice-versa. The piston or other reciprocating part is directly coupled to a sliding yoke with a slot that engages a pin on the rotating part. The shape of the motion of the piston is a pure sine wave over time given a constant rotational speed.

Acoustic Theory and Synthesis Frequency: Frequency means the number of cycles per second and depending on the amount of cycles per second determines how high or low pitched the sound is and the time that it takes to complete one cycle is called the period. Frequency is measured in Hertz (Hz). And An average human is able to hear sounds between 20Hz and 20‚000Hz. As the cycles per second increases‚ the smaller the wavelengths become‚ therefore there is a higher frequency which will cause
