Answer:
The total energy of the system is0.0375 J
Explanation:
Given;
mass of the object, m = 0.4 kg
extension of the spring, x = 8.8 cm = 0.088 m
Amplitude of the oscillation, A = 4.1 cm = 0.041 m
Total energy of the system, is the sum of all the mechanical energy which include Kinetic energy and potential energy.
E = K + U
At maximum displacement, Vₓ = 0, the total energy is entirely potential.
E = U = ¹/₂KA²
F = kx
k = F/x
k = (mg)/x
k = (0.4 x 9.81)/0.088
k = 44.591 N/m
E = ¹/₂KA² = ¹/₂ x 44.591 x (0.041)²
E = 0.0375 J
Therefore, the total energy of the system is 0.0375 J
Nuclear<span> fusion occurs in the core area or center of the Sun. Here, temperatures are around 15,000,000°C. Gravity pulls all of the mass of the Sun inwards, creating pressure so intense that </span>nuclear<span> reactions take place. The nuclei of hydrogen atoms smash together and fuse to form larger atoms such as helium nuclei. Hope this helps!! :) </span>

Answer:
C.As the two objects touch, thermal energy flows as heat from the warmer block to the colder block until particles in both blocks move at the same rate and reach the same temperature.
Explanation:
Heat is the transfer of thermal energy from an object at higher temperature to an object at colder temperature.
The temperature of an object is a measure of how fast the particles in the object move: the higher its temperature, the faster the particles move, the higher the average kinetic energy of the particles in the object. As a result, the particles of the object at higher temperature tend to transfer more energy (called thermal energy) to the particles of the object at colder temperature by colliding with them: this process continues until the particles of the colder object reach the same average kinetic energy as the particles of the warmer object, and this means that the two objects have reached the same temperature.
