Ohm's law says that V=IR
So you have 1.5=x*7.5
Divide 1.5 by 7.5 to get I=.2
Your current is .2Amps
Answer: Medium
Explanation: A medium is a substance through which a wave can pass. It can either be a solid, liquid or gas.
Answer:
4.08 s
Explanation:
Let the passenger took "t" time to catch the train
so in this case the total distance moved by the train + 5 m = total distance moved by the passenger
so we will have
distance moved by train is given as
![d_1 = \frac{1}{2}(0.6) t^2](https://tex.z-dn.net/?f=d_1%20%3D%20%5Cfrac%7B1%7D%7B2%7D%280.6%29%20t%5E2)
also the distance moved by passenger
![d_2 = \frac{1}{2}(1.2) t^2](https://tex.z-dn.net/?f=d_2%20%3D%20%5Cfrac%7B1%7D%7B2%7D%281.2%29%20t%5E2)
so we will have
![d_1 + 5 = d_2](https://tex.z-dn.net/?f=d_1%20%2B%205%20%3D%20d_2)
![0.3 t^2 + 5 = 0.6 t^2](https://tex.z-dn.net/?f=0.3%20t%5E2%20%2B%205%20%3D%200.6%20t%5E2)
![0.3 t^2 = 5](https://tex.z-dn.net/?f=0.3%20t%5E2%20%3D%205)
t = 4.08 s
