<span>it is meant to distinguish the number of polyatomic ions from the number of atoms in a given polyatomic ion. an example is Ca(NO3)2</span>
Answer:
Kinetic energy is the energy of a moving body while potential energy is the energy by vutue of it's position
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
Start at the big tree, and take the instructions
one at a time:
1). Walk 15 west.
2). From there, turn around and walk 2 east.
3). From there, walk 7 more east.
Where are you from the big tree now ?
Aren't you 6 west of it ?
I mean, let's see some common sense here !
