Answer:
Explanation:
Given
n=5
0.3 fraction recrystallize after 100 min
According to Avrami equation

where y=fraction Transformed
k=constant
t=time


Taking log both sides


At this Point we want to compute 



taking log both sides



Rate of Re crystallization at this temperature

Answer:
(a). The velocity of the object is -2.496 m/s.
(b). The total distance of the object travels during the fall is 23.80 m.
Explanation:
Given that,
Time = 1.95 s
Distance = 23.5 m
(a). We need to calculate the velocity
Using equation of motion

Put the value into the formula



(b). We need to calculate the total distance the object travels during the fall
Using equation of motion

Put the value in the equation



The total time is


We need to calculate the distance
Using equation of motion

Put the value into the formula


Hence, (a). The velocity of the object is -2.496 m/s.
(b). The total distance of the object travels during the fall is 23.80 m.
Answer:
The mass is inversely proportional to the acceleration so the acceleration a1 is twice that acceleration a2

Explanation:
The force of friction and the kinetic force make the law of mass in moving so





The forces are the same however at the moment to determinate the acceleration


are constant because they make the same motion however the difference of mass make the acceleration difference
