in a transistor amplifier, when the signal charges by 0.02V, the base current changes by 10MA and collector current 12IMA. if collector load RC=5Kohms and RL=10Kohms, find (1) current gain (2) input Impedance (3) A. C load (4) Voltage gain (5) power gain

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.

It is the areas with lines. this may sound a little confusing, but i hope it !

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
