<p>I put neither bc it was moving at a constant speed</p>

62

<p>@ohmloo‌ i put both but im not sure</p>

63

<p>Definetely not both, it is caused by accelerating charged particles… </p>

<p>E = Fe/q
Fe is a force, F=ma
There was no acceleration so def no electric field </p>

<p>A 48 can get me a 65. Praise the lord.</p>

<p>Not sure about last answer</p>

66

<p>@DAIMYO how is it electrostatic?</p>

67

<p>The answer is def electric field only. Jamesjunkers is incorrect. The charged particle needs to be accelerating for a MAGNETIC field. However any charged particle will have an electric field. Electric field only.</p>

68

<p>Patickod isnt it the sun has larger mass? It asked for sun vs pluto as opposed to pluto vs moon</p>

69

<p>And diffracted waves have wavelength 1cm. The slit being smaller is irrelevant it does not change the wavelength</p>

70

<p>no it asked for sun v pluto and sun v charon</p>

71

<p>Okay, I didn’t know the field one anyway, sorry </p>

<p>No, it did not mention the sun… </p>

72

<p>What if you put mass and frequency for the last question </p>

73

<p>@Howdyyall‌ no its pluto has a larger mass bc it asked sun to pluto and sun to the charon or whatever</p>

74

<p>Howdyyall , i wasnt very sure about tnhat one</p>

75

<p>Did you guys get something REALLY small for the acceleration of pluto? I got an answer that was below 1m/s^2 and it didn’t feel right but I kept it anyway. </p>

<p>Also, do we have a definitive answer for what an electric charge moving at constant velocity produces?</p>

76

<p>@howdyyall all you had to draw was 3 curved lines right? Regardless of wavelength </p>

77

<p>Do you think the wavelength mattered for the diffraction one, or is drawing the curve good enough? </p>

78

<p>A particle doesnt need to be accelerating for a magnetic field, it just has to be moving and charged.</p>

79

<p>Also its electrostatic because a spark is produced.</p>

80

<p>does anyone remember the antibaryon MC question?</p>
