Strength Meter circuits

1. A wire .5 meters long carrying a circuit of 8 amps is at right angles to a uniform magnetic field. The force on the wire is 0.4 N. What is the magnetic field's strength? 2. A wire that is 20 cm long is at right angles to a uniform magnetic field of a density of 0.3 N/amp-m. The current through the wire is 6 amps. What force acts on the wire? thanks for the equations, i was able to solve it.

You haven't been awake in class, have you? I'll leave this lot to to you except for 18B

I'm studying to be a personal training and have to make 3 programs, two with trainer and one take home, one hour each. My client is 18, just starting to play rugby for the first time and is at wing position. He is a complete beginner and has never used the gym or lifted any weights. He has decent fitness but is still far from an athletic level. he is a fast sprinter with a very slim build and has average strength. I want to: Increase his explosive speed and power, reaction time, cardiovascular fitness. Is this is a good exercise? (10 minutes not mentioned for warm up and cool down) Treadmill run pace level 7-8 with small rests of level 4 light jogging (LEG cardio) Steps with variations of faster tempo and jumps (coordination, LEG strength, explosive power) Pushup intervals of 5 with 10 second rest (upper body PUSH) 15 meter sprint back and forth when i choose (LEGS, reaction time, explosive power) Cable crossover with theroband (upper body strength PULL) Medicine ball lunge and core twist (LEG strength, coordination, CORE) This is a circuit and will be repeated once for a total of around 50 minutes, is there anything i'm missing? the client has been completely cleared by a GP and has no outstanding features/problems. Also how can i write the second PT program to be different but with the same goal? (I can do the take home one myself) Please rate. How can i deliver the same results while changing each of the exercises with others not here, adding plyometrics too. I'm having trouble writing programs. I'll make the warm up and cool down. SO: How can i change the whole exercise but get the same/similar results? want to add plyometrics too.

if your looking for explosive speed and power you are missing the heavy weight work, max strength = more power, an average strength player will need more than therabands. even wingers need to get in low at the breakdown, where are the compound lifts ? if your looking for plyo exercises, bounding and burpees are good but wingers are not usually jumping in the lineout. I don't see any back work, where is you concern for muscle balance for injury prevention ? sprint/ run routine no stopping between sprints I can't post images on here to explain some possible reaction time drills. with your medicine ball go back to back and pass to each other around body.
