- where you live?(11.8) KN A 41. 4.000times 10^3 L of propane gas is held in a tank at 25^circ C The tank has a moveable diaphragm to keep the pressure constant at 200 kPa. If the temperature falls to -5^circ C on a cold winter day,what volume will the gas occupy? (11.8)T/I
- 4. In experiments physicists routinely accelerate protons to speeds quite close to the speed of light. The mass of a proton is 1.67times 10^-27kg and the proton is moving with a speed of 0.99 c (a) Calculate the proton's momentum according to Newton's definition. (b) Calculate the proton's relativistic momentum. (c) Determine the ratio of the relativistic momentum to the Newtonian momentum. 5.The relativistic momentum of a particle of rest mass m and speed v is equal to 5mv.Calculate the speed of the particle.14. A An electron with a speed of 0.999c has a momentum that is equal to the momentum of a ship with a mass of 4.38times 10^7 kg moving at a certain speed Determine the speed of the ship. 7. If you were travelling on a spacecraft at 099c relative to Earth,would you feel compressed in the direction of travel? Explain your answer.Ku 8. Why do we not notice the effects of length contraction in our everyday lives?For example, why do cars not appear shorter when they drive past us at high speeds?
- 2) At what distance from Earth's surface is the acceleration due to gravity 7.33m/s^2 (9.97times 10^5m)
- The loudness of a sound is related to the logarithm of the ratio of the measured intensity, I, to a reference intensity, I_(0) The loudness, L, of a sound is measured in decibels, dB, and can be determined using the formula L=10log_(10)((I)/(I_(0))) If the intensity of the sound of a rocket launching is 4500 times that of a jet engine and the rocket has a loudness of 170 dB. then the loudness of the jet engine, to the nearest decibel, is square
- Question 31 (1 point) PRC4A17-A1-8 -3-7 A uniform bar 1.1 metres in length and having a cross sectional area of 11.5cm^2 is subject to a loading of 9000 Newtons Calculate the stress produced in kPa. square A I
