An arrow strikes a target causing an internal energy increase of 40.48j...
Here we know that internal energy of arrow has been increased by 40.48 J as it is striking to the target
so here by energy conservation we can say
initial kinetic energy of arrow = final internal energy of the arrow
so here we have
so here since increase in the internal energy is 40.48 J
so the kinetic energy will be given as
first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
