What else can I help you with?
A person exposed to radiation has no chance of survival. true or false?
False. The chances of survival for a person exposed to radiation depend on the type, dose, and duration of exposure. Treatment and medical interventions can help improve survival rates for individuals exposed to radiation.
3 All nuclear radiation consists of charged particles true or false?
False, neutrons are not charged and gamma rays aren't charged particles.
Why is there a false peak at diagram of Electron emission in electron gun?
A false peak in the diagram of electron emission from an electron gun often arises due to the presence of secondary electrons. When primary electrons strike the cathode material, they can cause the emission of secondary electrons, which may create an apparent increase in current or intensity at certain energy levels. Additionally, factors such as the thermal energy of the emitted electrons and variations in the electric field can contribute to this misleading peak. This phenomenon can lead to misinterpretation of the actual emission characteristics of the electron gun.
Do medium size stars become black holes true or false?
False. Only the most massive stars will become black holes.
What are the answers to Pearson Prentice worksheet convection and the mantle?
1.convection 2.radiation 3.conduction 4. 5. 6.false 7.true 8.true 9.false 10. False
What is always false about thermal black body radiation?
One common misconception about thermal black body radiation is that it depends on the material of the object emitting the radiation. However, in reality, thermal black body radiation only depends on the temperature of the object, not its material composition.
Tue or false radiation is the direct transfer of energy by electromagnetic waves?
True, radiation is the direct transfer of energy by electromagnetic waves, which can occur through processes like heat transfer in the form of infrared radiation or light emission in the form of visible light.
Is it true or false that the frequencies of radiation increase as the wavelengths increase?
False. The frequencies of radiation decrease as the wavelengths increase. This is because frequency and wavelength are inversely proportional in the electromagnetic spectrum.
Is it true or false that rough surfaces exert more friction than smooth surfaces?
True. Rough surfaces have more irregularities and asperities that create more contact points with another surface, resulting in higher friction compared to smooth surfaces.
Is it true or false that rough surfaces exert more friction than smooth surfaces.?
True. Rough surfaces have more irregularities and bumps that create greater resistance against motion, leading to higher levels of friction compared to smooth surfaces.
A person exposed to radiation has no chance of survival. true or false?
False. The chances of survival for a person exposed to radiation depend on the type, dose, and duration of exposure. Treatment and medical interventions can help improve survival rates for individuals exposed to radiation.
Can a polyhedron have either flat or curved surfaces?
false
Are animals are not affected by radiation true or false?
false. All animals are affected by radiation. Some can withstand more than others like cockroaches.
True or false cellular phones produce radiation?
True - they work by using microwave radiation.
Cancer is cause by radiation true or false?
true
3 All nuclear radiation consists of charged particles true or false?
False, neutrons are not charged and gamma rays aren't charged particles.
A person exposed to radiation has no chance of survival?
false because sunlight has radiation and all living things like humans has radiation
