Answer:
Explanation:
In order to solve this question we need to know that 
. Then we need to convert 4 minutes into seconds and cm into m. We can do that by multiplying the number of minutes by 60 (because there is 60 seconds in one minute) and dividing the number of cm by 100 (because there is 100 cm in one m). So.......
4min = 4 x 60s = 240s
300cm = 300/100 m = 3m
Now we know that distance = 300m, and that the time = 4min = 240s ⇒
⇒ 
What a relief ! That gives her time to step out of the way, before the ball
comes crashing down in the same place where she was standing.
V=IR
Potential Difference (v)= Current (A) * Resistance (Ω)
As V increases, R also increases.
