Calculate its average speed in meters per second
Answer:
5.77 m/s
Explanation:
Speed= Distance/Time
Distance= 40+ half of 40= 40+20= 60 m
Time= 8.8+1.6=10.4 s
Average speed= 60/10.4=5.769230769 m/s
Approximately, the average speed is 5.77 m/s
Answer:
the motion of an object in a circular path , in a fixed orbit
Answer:
Mechanical Advantage = Output Force/Input Force
Velocity Ratio = Driving Gear/Driven Gear
Explanation:
Answer:
Part a)
Direction of force is along the motion of charge
Part b)
direction of electric field is along the direction of motion
Explanation:
Part a)
As we know that the change in electric potential energy is equal to the work done by electric field
now from the equation of work done we know that
Direction of force is along the motion of charge
Part b)
As we know the relation between electrostatic force and electric field given as
direction of electric field is along the direction of motion
