Answer:
- c) 62.5 mA
- c) 9 seconds
Step-by-step explanation:
1. resistance is multiplied by 20/5 = 4, so current is multiplied by 1/4.
(1/4)(250 mA) = 62.5 mA . . . . matches choice C
__
2. distance is multiplied by 144/16 = 9, so time is multiplied by √9 = 3. The time it takes to fall 9 times as far is ...
3 × 3 seconds = 9 seconds . . . . matches choice C
Answer:
x=11/2
Step-by-step explanation:
1/2x-4=7+1/6x
1/2x-1/6x=7+4
6*1/2x-1/6*6=11 As 6 is the Lcm and we have to multiply it to the fractions.
3x-x=11 As 6 divided by 2 is 3 and 3 multiplied by x is 3x.
2x=11
x=11/2 OR 5 1/2
