I'm pretty sure its metals that make good conductors.
Answer:
In both nuclear and chemical reactions, two physical quantities are seen to be conserved and unchanging: the number of particles and the total charge. A constant number of particles in nuclear reactions does not imply that mass is conserved.
Explanation:
Answer:
Convection currents are caused by a temperature difference in gases and liquids. As one area becomes warmer than another the molecules have more energy and start vibrating more vigorously thus spreading out and becoming less dense. This means that the less dense parts will become more buoyant causing them to rise.
Explanation:
Answer:
3.98×10⁻¹⁹ J
Explanation:
Applying,
E = hf................. Equation 1
Where E = energy of the photon, h = planck's constant, f = frequency of the photon
From the question,
Given: f = 6.00×10¹⁴ Hz
Constant: h = 6.626×10⁻³⁴J.s
Substitute these values into equation 1
E = (6.00×10¹⁴)(6.626×10⁻³⁴)
E = 39.756×10⁻²⁰
E = 3.98×10⁻¹⁹ J
Hence the energy of the photon in joules is 3.98×10⁻¹⁹ J
