'C' is the only true statement on the list.
Step-up voltage transformers have a lower number of turns
in the primary than in the secondary winding.
For rotational equilibrium of the door we can say that torque due to weight of the door must be counter balanced by the torque of external force

here weight will act at mid point of door so its distance is half of the total distance where force is applied
here we know that

now we will have


so our applied force is 72.5 N
Answer:
Add the two speeds together.
Then, divide the sum by two. This will give you the average speed for the entire trip. So, if Ben traveled 40 mph for 2 hours, then 60 mph for another 2 hours, his average speed is 50 mph.
TRUE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I think its inductance. If its not then I think its none of the above
