A changed electroscope will discharge near a radioactive material because the radioactive material emits ionizing radiation (such as alpha and beta particles) that can ionize air molecules around the electroscope. This ionization causes the charge on the electroscope to leak away, resulting in discharge.
What else can I help you with?
What are the 2 ways how electroscope maybe changed?
Electroscope can be charged by conduction, where it comes into direct contact with a charged object transferring charge, or by induction, where a charged object is brought close to the electroscope inducing a separation of charges within it.
How can the current through a material be changed?
The current through a material can be changed by varying the voltage applied across the material. By adjusting the voltage, you can increase or decrease the current flowing through the material. Additionally, changing the resistance of the material can also impact the current flowing through it.
How is electrical energy changed to light energy in a circuit?
Either by the current heating a fine wire until it glows in the incandescent lamp, by an electrical discharge exciting agas or flourescent material in gas-discharge and flourescent lapms respectively, or by a quantum effect in the light-emitting diode.
Are materials changed when phyical properties are measured?
No, measuring the physical properties of a material does not change the material itself. The properties being observed, such as mass, volume, density, or color, are characteristics of the material and do not alter its composition.
How much the temperature of a material is changed by heat energy depends?
The change in temperature of a material due to heat energy depends on the specific heat capacity of the material. Different materials have different specific heat capacities, which determine how much heat energy is needed to raise their temperature by a certain amount.
What are the 2 ways how electroscope maybe changed?
Electroscope can be charged by conduction, where it comes into direct contact with a charged object transferring charge, or by induction, where a charged object is brought close to the electroscope inducing a separation of charges within it.
How the radioactive decay rate be changed?
The rate cannot be changed.
Has polonium and radium changed at all?
Being radioactive and unstable elements they are continuously changed.
Is there any way to change the average amount of radiation emitted from a radioactive substance?
No, the average amount of radiation emitted from a radioactive substance is inherent to the substance's decay process and cannot be changed. The rate of decay is measured by the substance's half-life, which is a fixed characteristic of the radioactive material.
Does the process of radioactive decay fall under the study of chemistry or physics or is it a combination of both?
Radioactive decay falls under chemistry, because the chemical properties of the substance are changed during radioactive decay.
How is the original rock material changed to igneous rock?
The original rock material changed to igneous rocks is the lava .,.,,., "I LOVE MY ANSWER'',..,
How do some nuclei change?
Atomic nuclei are changed by nuclear reactions or radioactive disintegration.
How has americium changed over time?
As all radioactive elements, isotopes of americium continuously decay.
Can transparent material can be changed into translucent and opaque and why?
yes, they can be changed by increasing the density of their molecules
How can the current through a material be changed?
The current through a material can be changed by varying the voltage applied across the material. By adjusting the voltage, you can increase or decrease the current flowing through the material. Additionally, changing the resistance of the material can also impact the current flowing through it.
How have hats changed in shape style and material over the years?
has hats changed over the years
What is SMART used for?
a smart material is a type of material used that can be changed by some of its own probities
