Answer:c
Explanation:
When the direction of current is towards the observer then the magnetic field around it will be in the form of concentric circles and its direction will be anti-clockwise when viewed from the observer side.
Whenever current is flowing in a current-carrying conductor then the magnetic field is associated with it and direction of the magnetic field is given by right-hand thumb rule according to which if thumb represents the direction of current then wrapping of fingers will give the direction of the magnetic field
they are miles per hour(mph),kilometers per hour(km/h),meters per second(m/s)
Answer:
C.
Explanation:
Ultraviolet light shining on the minerals will cause them to give off visible light.
Answer:
20 m/ s
Explanation:
change in velocity = 4m/ s


initial velocity = 0m/ s
- let velocity after 10s be v

cross multiplying

so the velocity after 10s will be 20m/s
