During conduction heat is transferred by the movement of currents within a fluid true or false

Electrons are extremely important to what area of technology? a) anti-aging research b) household product development c) electronics d) drug discovery

What is the energy in joules of a mole of photons associated with visible light of wavelength 486 nm?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
