Answer: yes u can use a 6.75 when measuring the pencil
In physics<span>, a </span>force<span> is said to do </span>work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). so in the proble, <span>She does NO work since the force she applies to the case is vertical and the direction of motion is horizontal. Work is the force times the parallel distance</span>
Answer:
C. Earth give me brainlest its correct! Hope this helps!
Explanation:
Answer:
The second wheel
Explanation:
The torque is given by
(1)
where I is the moment of inertia and a is the angular acceleration. If we take into account the moment of inertia of a disk and a ring ()for the first wheel) we have:
where we used that both wheel have the same mass. By replacing in (1) we obtain:
Hence, the second wheel (the disk) has a greater acceleration.
hope this help!!
