What type of instrument can detect the presence of an electrical charge?
a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.
What is the best vehicle tracking device?
If you ask the dealer if there is a tracking device which can be installed in the car, he will be able to advise you of the best type and what it can do. He would also be able to advise you in connection for value for money.

How have earthquakes been predicted in the past?
Historians believe that Chinese philosopher Chang Heng invented the first device to measure earthquakes in AD 132. It is described as a large urn with eight dragon heads popping out of it. Each head faced one of the eight principal directions of the compass- North,South,East,West,Northeast,Southeast,Northwest and Southwest. And a toadwith its mouth open squatted below each dragon head. When an earthquake hit, a ball would release from one or more of the eight dragons and fall into the toads mouth. By this, the direction of the approaching earthquqke could be determined. Reports indicate that Heng's device detected an earthquake 400 miles/ 644 km away. There were other devices like these to detect earthquakes but this was the best one. Devices to "measure" earthquakes were not very accurate in ancient times, in fact, there were hardly any such devices.
Do seismographs monitor earthquakes?
Scientists use seismographs to monitor earthquakes. Though, a seismograph merely registers an earthquake. By using at least three seismograph stations, and using triangulation, the epicentre of the earthquake is able to be plotted.
Would you be able to detect the swaves in Antarctica if an earthquake hit in northern Alaska?
No. S waves are really weak so it wouldn't last to that extent.
Are instruments able to detect the light?
Yes. Specialized instruments called photodetectors are able to sense light.
What technology had to be invented before Ernest Rutherford could perform his experiments with gold foil?
A device able to detect alpha particles and count them.
What is a device able to supply electrical energy called?
Nonconductor
How a seismograph is used?
A seismograph is located under the ground. When there is an earthquake, the ground shakes, which also shakes the pen on the seismograph, making it move along the paper, drawing lines. To know how strong the earthquake was, scientist can look on the paper. The bigger the lines, the stronger the earthquake was.
Can darkrai learn earthquake?
No, Darkrai is not able to learn Earthquake.
Can Gallade learn earthquake?
Yes, Gallade is able to learn Earthquake through the use of the Earthquake TM.
What level does grotle learn earthquake?
Grotle is not able to learn the move Earthquake by leveling or by TMs. It's evolved form Torterra is able to learn Earthquake at level 32.
How are you able to detect this HIV?

No
What is a simple way to detect EMI?
You can get an EMI detection device that will be able to locate exactly where EMI is being given off such as TV's Computers, Microwaves. A much easier way would be to look around for any medium or larged sized eletronic devices, they are most likely giving off EMI.
