Answer:
Ferris Wheel is the answer
Answer:
2960 N
Explanation:
Convert rev/min to rad/s:
150 rev/min × (2π rad/rev) × (1 min / 60 s) = 50π rad/s
Sum of forces in the centripetal direction:
∑F = ma
T = m v² / r
T = m ω² r
T = (0.2 kg) (50π rad/s)² (0.6 m)
T = 2960 N
Well for example if you’re throwing a ball The force that moves the ball "up"
must overcome (be larger than) the downward force of the ball's weight.
Once the upward "force of the throw" overcomes the weight, it must then accelerate the ball upward, in order to give an initial upward speed.
Newton's formula: Fnet = ma
indicates that the acceleration (a) will equal the *excess upward force* {once the weight force is cancelled} divided by the ball's mass.
so in summary:
Fnet in Newtons will be the child's UPward force minus the ball's weight.
As per right hand thumb rule if we put our thumb of right hand along the current in the wire then curl of fingers will show the direction of magnetic field.
So here as we can see the fingers in the above case is curled such that in front position its showing towards right.
So the direction of magnetic field near the student in front position must be towards Right.
