Answer:
29.3 rad/s
Explanation:
Moment of inertia in straight position, I1 = I
He takes 2 rotations in 1.5 second
So, Time period, T = 1.5 / 2 = 0.75 second
w1 = 2 x 3.14 / T = 2 x 3.14 / 0.75 = 8.37 rad/s
Moment of inertia in tucked position, I2 = I / 3.5
Let the new angular speed is w2.
By the use of conservation of angular momentum, if no external torque is applied, then angular momentum is constant.
L1 = L2
I1 w1 = I2 w2
I x 8.37 = I / 3.5 x w2
w2 = 29.3 rad/s
No.
The flow of electrons is in the opposite side to the flow of convectional current.
Convectional current is considered to be the flow of positive charges from the positive terminal of the cell called anode to the negative terminal of the cell called cathode through the external circuit.
Electrons flow from cathode to the anode of the cell through the external circuit.
Answer: PLESSE IGNORE THIS I NEED POINTS IM SORRYY
Explanation:
Answer:
Honestly I cant understand that so please explain it someone
Explanation:
Answer:
Clockwise movement
Explanation:
Players rotate “clockwise” through each of these positions. Another way to remember it is the player in 1 serves first, the player in 2 serves next, the player in 3 serves third, and so on. The order of rotation is set at the beginning of the game and maintained throughout the game (excepting substitutions).
Hope this helps!! :))
