Answer:
The upper limit of metamorphism occurs at the pressure and temperature of wet partial melting of the rock in question. Once melting begins, the process changes to an igneous process rather than a metamorphic process. During metamorphism the protolith undergoes changes in texture of the rock and the mineral make up of the rock.
Explanation:
i hope this helps
P=w/t
w=15
t=3
therefore, 5 watts (b)
Mass, m=22 kg
It is given that Force, F = 88N
Acceleration, a=4 m/s 2
