Answer:
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Explanation:
Answer:
it is because it do not produce smoke like fuel from wood.

Explanation:
Given parameters:
Mass of Gold = 12400g
Initial temperature = 23°C
Final temperature = 1064°C
Unknown:
Energy required to melt = ?
Solution:
The amount of heat required to cause this temperature change to heat the gold bar is given as;
H = m c Ф
m is the mass of gold bar
c is the specific heat capacity of gold
Ф is the heat change
Specific heat capacity of gold = 0.129J/g°C
H = m c (Ф₂ - Ф₁)
H = 12400 x 0.129 x (1064 - 23) = 1665183.6J

Answer:
When the electrons jump to a higher energy state, they release energy as electromagnetic radiation, light.
Explanation:
When the solar wind gets past the magnetic field and travels towards the Earth, it runs into the atmosphere. As the protons and electrons from the solar wind hit the particles in the Earth's atmosphere, they release energy – and this is what causes the northern lights.
