scan packages and detect unusual objects.
We see objects, because:* Light from the objects reaches us. * Our eyes (and brains) are especially equipped to detect such light.
Are you talking about a reference point?
Our eyes are specifically designed to detect light. The objects reflecting the light change the property of light, including its intensity and color; this allows us to make conclusions about the objects it was reflected from.Our eyes are specifically designed to detect light.

Yes, infrared radiation can detect heat. Infrared sensors are designed to detect and measure the infrared radiation emitted by objects, including heat emitted by living organisms or warm objects.
they use sonar like bats do to detect objects that are in their path
All objects have a gravitational pull on all the other objects. even your computer monitor has a slight amount of pull on you. The reason you don't notice them is that they are so insignificant that we can't even possibly detect the pull with the best technology. lets say that your computer monitor was 5 kg, you weighed 80 kg, and you were sitting 1 meter away. the force on you would by the computer would be 0.00000002668 newtons (that's really small). the earth has a noticeable force on us, but look how big it is! so any object with mass has a gravitational pull on any other object with mass, we just can't see or feel because it is so small.

Nickel, cobalt, and iron.
Are you talking about a reference point?
the answer to that is by vibration. in the wind.
It is used to measure radiation and is commonly used to detect objects that produce nuclear radiation.
