What couple is needed to hold a small single-turn coil of area 5 cm2 in equilibrium, when it carries a current of 10 a and is placed with its axis at right angles to a field of flux density 0.15 t. what couple would be required if the coil had 20 turns?

1 - wave length

2 - amplitude

3 - crest

4 - trough

explanation:

duh.

hi i’m sorry to call us today so we will get back with y’all and we will have to do it haha omg was the day

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
