Answer:
2ohms
Explanation:
the net resistance is given by
1/R=1/R1 +1/R2,we are supposed to find R
thus by making R the subject ....
R=R1•R2/R1+R2
R=3•6/3+6
R=18/9 =2Ohms
For calculating any of these, you can use the relationship of mass, volume & density as:
Density = mass / volume

Answer with explanation:
If a electric charge is at rest or moving in an electric field in space it experiences an electric force mathematically given by

The force on the charge is independent of motion of the charge. Thus the charge is accelerated in an electric field.
As compared to electric field a magnetic field can only exert force on moving charge and not a stationary charge and the force is mathematically given by

where
v is the velocity vector of the charge.
The type of environment that the Organisms lived in is usually in shallow sea or the sea floor.
Both of them are deposited in deep marine environment and accumulated by floating organisms
Total Mechanical Energy = Kinetic Energy + Potential Energy
Here, K.E. = 500 J
P.E. = 1500 J
Substitute their values,
E = 1500 + 500
E = 2000 J
In short, Your Answer would be 2000 Joules
