A train moves with a constant velocity for 15s for 155m. How fast is the train moving?
1 answer:
Answer: 10.3m/s
Explanation:
In theory and for a constant velocity the physics expression states that:
Eq(1): distance = velocity times time <=> d = v*t for v=constant.
If we solve Eq (1) for the velocity (v) we obtain:
Eq(2): velocity = distance divided by time <=> v = d/t
Substituting the known values for t=15s and d=155m we get:
v = 155 / 15 <=> v = 10.3

I think the answer would be C
Answer:
Given: V=12 V
I=2.5 mA
Let the resistance be R
By Ohm's Law,
V=IR
12=2.5×10−3R
R=4.8×103 Ω
