The perfect elastic Collision ball will hit the door first because the clay is heavier and will take more time
Some substances look alike and the density can help you determine which is which. It also helps to tell which is heavier than the other.
Answer:
20 mA
Explanation:
We have given that the transformer convert 120 V to 12 V means it is a step down transformer
The turn ratio of the transformer is given as
here
is primary voltage and
is secondary voltage
As the voltage decreases from primary to secondary so current will increase from primary to secondary
We have given output current that is secondary current so primary that is input current will be less
So input current
