Freezing, as at the begginning they could slide past one another so the substance was a liquid and then it turned into a solid where the particles are even closer together and they have strong attractions between them
You don't say what the insulators are insulating from ... heat or electricity.
Here are some of each:
Heat insulators:
-- Air (between the inner and outer bottles of a thermos bottle)
-- Wood (around the handle of a frying pan)
-- Cloth (an oven mitt)
Electrical insulators:
-- rubber
-- plastic
-- wood
-- cloth
-- air
Explanation:
Part (1) :
A worker pushes a box in a factory. We know that the Newton's third law of motion tells that there exist an equal and opposite reaction when a force is applied to an object. Here, the magnitudes of the forces are equal when a worker pushes a box.
Part (2) :
When some contents are removed, and now when pushed the box slides across the floor at constant speed. Then the Newton's third law will be followed. So, the magnitudes of the forces are equal.
Part (3) :
When the worker pushes harder, and the box accelerates. So, the force exerted by the worker on the box is greater.
Answer:Chemical energy
Explanation:, Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.
Answer:
Modulation
Explanation:
Modulation is the the process whereby a waveform has one or more of it's properties varied. Amplitude, frequency and phase are all properties of a waveform which can be varied hence Modulation is the process of sending data over a signal by varying either its amplitude, frequency or phase.
