- QUESTION 1 Mass is a key part of "weight". In terms of formula, what is the relationship between mass and weight? Weight is a force, so it is equal to mass times an acceleration. On earth, this "acceleration" is g=9.8 m/s^wedge 2 Weight is a force so it is equal to mass divided by an acceleration. On earth this "acceleration" is g=9.8m/s^wedge 2 Weight is equal to mass; if your mass is 80 kg, so is your weight. Weight and mass are related conceptually, but there is no specific formulaic relationship between the two. They are both fundamental properties of matter.
- Which of the following best describes the result of how dry magnetic particles should be applied on the surface being examined per MT-1? a. A thick coating settles on the surface being examined. b. A heavy, concentrated coating settles on the surface being examined. c. A heavy, uniform dusting settles on the surface being examined. d. None of the above
- 11. How much work would you have to do to carry that weight back up to the original height?
- 4.A fire truck emitting a 450 Hz signal passes by a stationary detector. The difference in frequency measured by the detector is 58 Hz. If the speed of sound is 345m/s how fast is the fire truck moving?
- 35. A 62-kg runner starts from rest and reaches a speed of 7.2m/s in 2.3 s with negligible air resistance.The runner then runs the remainder of the race at a constant speed of 7.2m/s under the influence of a constant alr resistance of 28 N. a) Find the average power needed to accelerate the runner. b) Find the average power needed to sustain the constant speed of 7.2m/s for the remainder of the race.
