Explanation:
this is the answer.....................
.
-- The net effective resistance of three 1200-ohm resistors in
parallel is (1200/3) = 400 ohms. That's what the battery sees.
-- Power = (voltage)² / (resistance)
= (12²) / (400)
= 144 / 400
= 0.36 watt .
There's no such thing as "power in the circuit".
0.36 watt is the power dissipated by the resistors.
It's the rate at which the battery must supply energy,
and the rate at which the resistors blow it off in the form
of heat, for as long as the battery lasts.
Answer:
an absorber of x-ray
Explanation:
To make x-ray detection/vision work, you will need at least two items: a source of x-ray and absorbed or x-ray.
The object you want to see itself doesn't have to be the source, but it has to absorb some of the rays instead. When doing a chest x-ray test, the medical employee will put your chest between absorber and source. The heart can absorb some of the rays so it will appear more white than lungs who made of air and won't absorb the rays.
The answer that fits in the blank is truck.
Inded, truck or trucking is moving the camera from one side to the other side to make the objects to appear closer or farther away.
There are some basic movements of the camera to record video footage: zoom, pan, tilt, dolly, truck, pedestal and rack focus.
