show and describe how torque is calculated. First show the derivation symbolically

What is the torque about the pivot point shown by the 10.0 N force, in N•m? (Pay attention to the sign.) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 8.0 N 10 N -130° 25 cm 75 cm

Given the two vectors r and F shown above, choose the direction of the resulting torque vector. left swer Tries 0/2 right in Discussion Senc out up

Looking for a solution that involves all torques. How to calculate it using torque? Thank you

Arithmetic question. Write only the final value of the answer.   Suppose you did the rotational dynamics labs with a 200g solid sphere. The sphere was placed at rest at the 100cm mark on the track which is inclined at 150 angle with the table. What is the translational kinetic energy in (J) of the sphere as it leaves 0 mark of the track? Write your answer with TWO decimal places.

What is the direction of the torque for each of the following situations?   right is in the positive x-direction left is in the negative x-direction up is in the positive y-direction down is in the negative y-direction     r vector is up, F vector is down.   r vector is down, F vector is to the right   r vector is to the right, F vector is also to the right.   r vector is to the right, F vector is down.   r vector is to the right, F vector is up.   r vector is up, F vector is to the left   1. Positive (out of the page, counterclockwise) 2. Negative (into the page, clockwise) 3. Zero
