Answer:
Explanation:
From A to B
distance traveled with velocity in time
from B to C
distance traveled is 0.5 d with and
velocity for half-half time
divide 1 and 2 we get
Now average velocity is given by
taking common
Answer: Less than 4 ohms
Explanation:
We have three resistors with the following resistance:
Now, when the resistors are connected in parallel, the total resistance is calculated as follows:
Isolating :
Rewriting with th known values:
Finally:
Hence, the correct option is less than 4 ohms.
