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.

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 :)

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%

Physics

Good day . I’ve been asked to calculate theoretical deflection My load = 0.981 N , length =560mm , youngs modulus = 207GN/m^2 , breath = 19.36, depth=3.07. Someone please assist me . My answer was incorrect.

deflection can be calculated by taking the double integral of the Bending Moment Equation, M(x) divided by EI (Young's Modulus x Moment of Inertia).
