Since the object is dropped from some height so its initial speed must be zero
acceleration of the object is due to gravity
so we can use kinematics to find the time it will take to drop by x = 22 m
Now the speed after 2.12 s will be given as
so above is the speed and time
Answer:
mercury and alcohol
ii) used to test temperatures
Answer:
Its is dividing by 2
Explanation:
It starts with 100 them it goes to 50, 25, 12.5 so its a cycle of dividing by 2
