Answer:
0 m/s
Explanation:
Average velocity of an object is given by the net displacement divided by time taken. Displacement is equal to the shortest path covered by the object.
In this problem, a player runs the length of the 30-meter court and back. The player does this three times in 60 seconds.
As the player runs the court and returns to the original point. It would mean that the shortest path covered is 0.
Average velocity = displacement/time
v=0/30
v = 0 m/s
Hence, the correct option is (1).
Air resistance force
tension force
spring force
frictional force
normal force
gravitational force
applied force
please give me brainly:)
The distance is the total distance she walked which is 16 meters adding the 6 meters to the corner and 10 meters to her friend's apartment. Her displacement is the distance from her original starting point so you set up a triangle with side lengths of 6 and 10 and solve for the hypotenuse which gives you a displacement of 11.66 meters.
True if you have proper stance and use your body the right way then the ball will be below your waist to allow for more control.
The resistance of the cylindrical wire is 
.
Here 
is the resistance, 
is the length of the wire and 
is the area of
cross section. Since the wire is cylindrical 
.
Comparing two wires,
Dividing the above 2 equations,
Since 
The above ratio is
We also have,
The current through the Silver wire will be 4.23 times the current through the original wire.
