Grade 8 SCIENCE BASELINE - 2020-2021 Question: 1-39 To bring heavy boxes down a fight of stairs. Tyrone uses a camp. He shoes the boxes down the ramp. The movement transforms ce type d energy into the fons made togos

the way that most of the energy is transformed?

potential energy into chemical energy and mechanical energy

o potential energy into light energy and mechanical energy

o potential energy into sound and chemical energy

O potential energy into heat and kinetic energy

This question is unclear, the comprehensive question is:

To bring heavy boxes down a flight of stairs, Tyrone uses a ramp. He slides the boxes down the ramp. The movement transforms one type of energy into two other forms. Which of the following describes the way that most of the energy is transformed:

ANSWER:

Potential energy into heat and kinetic energy

Explanation:

According to this question, a ramp is used to bring heavy boxes down a flight of stairs. Tyrone does this by sliding the boxes down the ramp. The ramp is in a fixed position i.e. not moving, meaning the energy in the ramp is POTENTIAL ENERGY.

However, when the boxes slide down the ramp, the potential energy transforms to energy due to motion called KINETIC ENERGY, and HEAT ENERGY, which is caused by the friction between the boxes and the ramp.

Therefore, the potential energy of the ramp is transformed to kinetic energy in the boxes and heat energy.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
