Answer:
Conduction is the transfer of heat energy by direct process.
Radiation is the transfer of heat energy with electromagnetic waves
Explanation:
There are two types of change in matter: physical change and chemical change. ... This is called the Law of Conservation of Matter. It states that matter can never be created or destroyed, only changed and rearranged.
Answer:
37.5 m/s
Explanation:
Using the law of conservation of energy, potential energy equals kinetic energy hence
Therefore
where g is the acceleration due to gravity, m is the mass of the object, h is the height and v is the speed of the roller coaster
Taking g as 9.81 then
