Web15 aug. 2024 · Answer: The source of electricity in a torch depends on what type of torch we are using. Mostly the torches get energy from the batteries we place in them and thus the energy is chemical energy. In some cases as seen now, the torches are run from solar energy and thus the energy is solar energy. Web17 okt. 2024 · k = (4.90 N)/ (0.01 m) k = 490.5 N/m. Now that the spring constant is known, the potential energy can be calculated using the formula above. If the spring in the example above is extended 20 mm from the equilibrium position, the potential energy can be calculated as follows: PE = 1/2kx2. PE = 1/2(490.5 N/m) (20 mm)2.
Web23 apr. 2024 · Mechanical Energy to Thermal Energy. Mechanical energy is energy associated with the motion and position of an object. When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy. … Web17 jul. 2024 · Energy stored in an electric field - Means the Potential Energy (electric) in that space. You do not even need to know volume for energy stored in electric field. It has three equations. PE = (1/2) C [V (net)^2] where C is capacity and V is 'electric potential'. I am sure you can find the other two online.
