Hello!
I'm just going to ignore the name of the building and just do the math
1 foot is equivalent to 0.3048 meters
if the building is 1368 feet tall, multiply it by 0.3048 to get 416.9664 meters
I hope this helps, and have a nice day!
Yes, if the mass starts at rest, <u>the change in speed will be equal the final speed</u>, because:
Δv = Vf - Vo
How Vo (Initial velocity) is equal zero, we simplificate:
Δv = Vf
Then, the change of the speed, if the mass starts at rest, will be equal to final velocity.
Greetings.
The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals
I = 6A
V = 94V
According to ohm's law ,
V = IR
R = 94 / 6
R = 15.66 ohm
