Answer:
endothermic energy or chemical energy
Explanation:
An endothermic process increases the enthalpy H of the system, during which the closed system (usually) absorbs thermal energy from its surroundings.
Chemical energy is the form of potential energy in which energy is stored in chemical bonds. The breaking of chemical bonds absorbs energy, while the formation of new bonds releases energy.
Answer:
In statics condition and if is a body is over plane surface N = mg
In all cases which a body is on a ramp force N will be smaller than mg, and depending on the level of the ramp (bigger the ramp smaller force N)
Explanation:
See annex (Figure 1)
We can see with the help of force diagram the relation between N force and mg
Lets look first the body on the ramp assuming there is not movement
The sum of forces alog y axis = 0
mg* cos∠ BAC = N (normal force)
So N is always a fuction of mg and of the cosine of the inclination angle, and the cosine of angle varies from value 1 when the angle is 0 (look the case where the block is on the surface without inclination N = mg ).
And as the inclination increase the value of cosine will become smaller and so will N force which is directly proportional of cosine of the inclination angle
Therefore we can say that force N is always minor than mg unless in extreme case where the block is over the surface in which case N takes its maximum value N = mg
