Answer:
Explanation:
Since the cardinal and ball have the same kinetic energy, it is possible to determine the ratio between speeds. (c for cardinal, b for baseball)
The ratio is obtained by multiplying each side by 
:
The value of this ratio is:
Answer and Explanation:
Using Gauss's law,
If r>a
then charge enclosed in all the three cases is same as Q.
So Electric field for all three is same.
So {1,1,1}.
(b) r<a,
Charge enclosed in case of shell is zero since all charge is present on the surface. So E = 0.
Charge enclosed by incase of point charge is Q.
Charge enclosed in case of sphere is Qr3/a3 which is less than Q.
So ranking {2,3,1}
It would be very chaotic... For example anything that was not attached to the Earth will probably go flying off into space in a straight linear line. If gravity disappeared the Earth's atmosphere would float into space so other planet's atmospheres would also flow into space. Planets will break apart into pieces and go off in space since planets are held together by gravity.
Imagine gravity is a string... Once you let go that string or quote-unquote "turn off" gravity everything will go flying into linear lines out into the vastness of the cosmos. I hope this helps if you need any more examples for have any other questions please let me know. Have a blessed day. :')
