A light bulb converts electrical energy into light energy and also some thermal energy. The amount of electrical energy is 50 Joules before the conversions.

Answers

Answer 1

Answer: If the amount of electrical energy is 50 Joules before the conversions, then it would be 50 Joules after the conversion.

According to law of conservation of energy, we cannot create or destroy energy so it remains constant

Hope this helps!

What is the main cause of erosion

Answers

Erosion is mainly caused by water, wind, and gravity.

Erosion is caused by human activities like excessive construction, agriculture, surface mining and forestry. Removing the vegetative cover accelerates erosion, which is often caused by grazing, logging or cultivating. In some cases, it can be removed by pests like pigs, rabbits and goats.

15 POINTS! What are some differences and similarities between Electromagnetic and Mechanical waves?

Answers

Elecromagnetic waves can travel through a vacuum, but a mechanical wave cannot.Mechanical waves can only exist in a medium, such as air or water. Electromagneticwaves behave like waves and particles, but mechanical waves only behavelike waves.

The difference between newtons first law of motion and newtons third law of motion

Answers

The difference is two laws of motion.

Answer : Newton's first law of motion (also known as Law of Inertia) describes about the tendency of an object to resist change from its state of rest / motion / direction (inertia).

Whereas, Newton's third law of motion tells us that forces exists in pairs. It talks about the action & reaction forces, which are equal in magnitude but opposite in direction.

In this way, Newton's third law of motion is different from Newton's first law of motion.

Which statement describes between a cup if cold water and a cup of boiling water

Answers

The thermal energy keeps these two changing their temperature over time.

The surrounding temperature (environment) clearly effects the cold water AND the boiling water.

Eventually, both would reach an equilibrium in temperature.
