Answer:
2.4 × 10 ²¹ N/C
Explanation:
The lead-196 nucleus has 82 proton
Q ( charge on the nucleus ) = 82e where e = 1.602 × 10⁻¹⁹ C
Q = 82 × 1.602 × 10⁻¹⁹ C = 1.314 × 10⁻¹⁷ C
vp ( volume of proton ) = 4/3π r³
V, volume of lead nucleus = 4/3πR³
4/3πR³ = 196 × 4/3π r³
R = ∛(196r³) = 5.81 r = 5.81 × 1.20 ✕ 10⁻¹⁵ m = 6.97 × 10⁻¹⁵ m
magnitude of the electric field = KQ/R² = 8.99 × 10⁹ × 1.314 × 10⁻¹⁷ C / (6.97 × 10⁻¹⁵ m )² = 2.4 × 10 ²¹ N/C
Answer:
false
Explanation:
the planet saturn rotates around the sun at 21,637mph
the planet mars rotates around the sun at 53,979mph
half the speed of mars is 26,989.5mph
Answer:
Isotopes
Answer:
The number of neutrons can vary, but not protons. This is called an isotope. An example is deuterium, an isotope of hydrogen with an extra neutron, but the same number of protons.
