Frying a pancake is an example of a)conduction because the metal of the frying pan conducts heat to the pancake.
Answer:
The sun is mainly made up of 75 percent hydrogen and 25 percent helium by mass; the sun's is also composed of less than 0.1 percent various metals and elements, including neon, iron, oxygen and carbon. These atoms form hot plasma that is interwoven with the sun´s magnetic fields.
Hope i helped :)

Answer:
the kinetic energy of the particle is 3.872 x 10⁻¹³ J
Explanation:
Given;
mass of helium, m = 6.64 x 10⁻²⁷ kg
speed of light, c = 3 x 10⁸ m/s
3.6% of speed of light, c = 0.036 x 3 x 10⁸ m/s = 1.08 x 10⁷ m/s
The kinetic energy of the particle is calculated as;
K.E = ¹/₂mc²
K.E = ¹/₂ x (6.64 x 10⁻²⁷) x (1.08 x 10⁷)²
K.E = 3.872 x 10⁻¹³ J
Therefore, the kinetic energy of the particle is 3.872 x 10⁻¹³ J
