Answer:
My best friend lol cuz since quarantine i didn't see her
Answer:
3.1 m/s
Explanation:
The total distance she has to run is the addition of the three lengths:
47 + 63 + 76 = 186 meters.
She needs to cover it one minute (60 seconds). Therefore her speed must be:
186 m / 60 s = 3.1 m/s
If it is a true or false question then it is true
A- electric forces only - WHEN The force exerted on a stationary charged object is nonzero.
B- magnetic forces ONLY - The magnitude of the force depends on the charged object's direction of motion.
C- both electric and magnetic forces - The force is proportional to the magnitude of the charge of the object on which the force is exerted.
D- neither electric nor magnetic forces- The force exerted on a moving charged object is zero.
(vi)- The force exerted on a charged object is proportional to its speed- magnetic forces only
