Direction. Velocity is a vector that describes both speed and direction, while speed is a scalar that describes only speed regardless of direction.
B Yea that should be the right answer
Answer:
6.5454 m
Explanation:
Let the distance from the wire carrying 3 A current is x
Then the distance from the the carrying current 8 A is 24-x
We know that magnetic field due to long wire is given by
It is given that magnetic field is zero at some distance so
Here
So
Answer:
if somthing is warm or if somthing moves it usally has energy
25 volts
Explanation:
Use Ohm's law to find the potential drop:
V = IR
= (0.5 A)(50 ohms)
= 25 volts
