State and explain 5 laboratory rules

• Know locations of laboratory eyewash stations, fire extinguishers and the emergency exits in case of emergencies, and wash exposed areas such as hands before leaving the lab. This is to ensure all traces of chemicals are removed inside and not taken out. • Avoid skin and eye contact with any chemicals to avoid getting hurt - be attentive and careful but report any incidents so experienced indi... more

Physics and Technology

Physics Generating New Technology: Newton's law of motion helped in the development of rockets. Bernoulli's principle helped in the development of an airplane's wings. The concept of thermodynamics helped in the development of heat engines. The heating effect of electric current helped in the development of incandescent bulbs and vacuum diodes. The chemical effect of electric current is used in el... more

How is the conservation of energy apply to a pendulum swinging

In the rest position (at equilibrium) before the pendulum is swinging its KE = 0 and the GPE = 0. As the pendulum moves upwards it gains both KE and GPE and at its max height GPE = maximum, but there is a small moment when at the max height the pendulum does not move, so even though as the pendulum climbed upwards it gained KE, right at the top where it halts for just a split second, whilst GPE... more

Physics

Different between potential difference and current

Current: The rate of flow of charges Potential difference: Work done to move a unit charge between two points in an electrical circuit. in very very very simple terms: Current: how quickly the charges (electrons) are moving in a circuit Potential difference: how much energy is needed to move these charges between 2 points in a circuit. Any more questions? Feel free to message me :)

Physics

A space shuttle has an acceleration of 29 m/s2 . The initial velocity is 2 m/s. Calculate the velocity of the shuttle after 8 seconds.

Given Data: Acceleration = a = 29 m/(s)^2 Initial Velocity = Vi = 2 m/s Time = t = 8 sec Final Velocity = Vf = ? Solution: According to Newton’s First Law of Motion, Vf = Vi+at -------eq(1) Put the values from given data in eq(1), we get, Vf = 2+(29)(8) = 234 m/s

How do physics and technology are connected with each other?

Physics has vast applications and one of them is in the field of technology. An example would be the technologies such as nuclear reactors which can be utilised to generate huge amounts of energy are based on the principles of nuclear physics.

Physics in relation to Technology

I would say Physics is integrated into technology. Anything to do with movement of objects, SUVAT. Even when we think about data movement that is via waves travelling to a satellite and back via networks built on circuits etc etc. Many technologies require the use of Physics, programming , mathematics biology chemistry. What we have technology wise is continuously in development with the use of Ph... more
