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

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

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 :)

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

A Diesel engine is supplied with 6000j of chemical energy and usefully transfers 2100j what is the efficiency

efficiency = useful power out/total power in 2100/6000=0.35 could also be written as a percentage so 0.35=35%

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.
