Their momenta are equal, but the 50g ball has twice as much kinetic energy as the 100g ball has.
Answer: E = 39.54 N/C
Explanation: Electric field can be determined using surface charge density:
where:
σ is surface charge density
is permitivitty of free space ()
Calculating resulting electric field:
E = 39.54
The resulting Electric Field at any point is 39.54N/C.
A golf ball less resistance-smaller object
Her potential energy is 11.25 kj
Ionic compounds are always salts forming between a metal and a non-metal
Examples include, but are not limited to
NaCl
BaF2
Cs2O
Sometimes an ionic compound can be composed of a metal + a polyatomic ion
Examples of polyatomic ions include
Phosphate PO4 3-
Chlorate ClO3-
Some ionic compounds with these polyatomic ions include
CsClO3
Ba3(PO4)2
Hope this helps. I can’t do much good if I can’t see the options.
