Answer:Consider a rechargeable lithium cell that is to be used to power a camcorder. Construct a problem in which you calculate the internal resistance of the cell during normal operation. Also, calculate the minimum voltage output of a battery charger to be used to recharge your lithium cell. Among the things to be considered are the emf and useful terminal voltage of a lithium cell and the current it should be able to supply to a camcorder.
Explanation:
Answer:
Explanation:
As we know that the magnitude of electric field intensity is given as
now we know that intensity of the wave is given as the product of energy density and speed of the wave
so intensity is the energy flow per unit area per unit of time
so the energy that flows through the area of 0.0259 m^2 in 11.7 s is given as
What humans looked like and tools they used and the animals that have been alive through the centuries.
