A thin disk rotates about an axis that goes through its center perpendicular to its plane. The disk is rotating clockwise and speeding up. What can be said about the angular speed and acceleration of the disk? Angular speed is positive, angular acceleration is negative Angular speed is negative, angular acceleration is positive Angular speed is positive, angular acceleration is...
Rolling and slipping: A relative motion approach Mech Name HW-45 6. A cylinder of radius R is placed on top of a wooden board. They are initially at rest. The board is then pulled to the right by a constant horizontal force of magnitude F on a frictionless surface, The cvlinder is observed to roll counterclockwise without slipping cylinder wooden...
1. Determine the future value on a savings of $5,000 for 6 years (N) compounded quarterly, at 3% per annum. 2. Determine and compare using same information on #1 above but compounded monthly 3. You have an opportunity to invest your $25,000.00, in a local company that has offered to pay you 8% in the first year, and 9% in...
An ant is taking a two-dimensional random walk on a flat surface. We will distinguish steps that the ant takes with its feet from the random walk (RW) steps, of length δ, which are made up of lots of footsteps. In a RW step, the ant choose a direction randomly and walks distance δ in that direction. She then choose...
Motion of Particle Puntos:5 The motion of a particle moving in a circle in the x-y plane is described by the equations: r(t)=9.54, Θ(t)=7.88t here Θ is the polar angle measured counter-clockwise from the x-axis in radians, and r is the distance from the origin in m. Calculate the y-coordinate of the article at the time 2.50 s. Enviar Respuesta...

The first item istossed upward with initial velocity v.-3.5m/s at h-/3 m above the pound. Aher 5 s, the other iem istossed dowaward with initial velocity of -n from the same height. Both of the items move...
Question: A three-phase line has an impedance of 1 + j2 Ω per phase. The line feeds two balanced three-phase loads that are connected in parallel. The first load is Y-connected and has an impedance of 20+j40 Ω per phase. The second load is ∆-connected and has an impedance of 30-j60 Ω per phase. The line-to-line voltage at the load...
-/1 points SerPSE10 26.2.P.013.MI. My Notes Ask Your Teacher Suppose you wish to fabricate a uniform wire from 2.50 g of copper. The wire is to have a resistance of R 0.520 n and all the copper is to be used (a) What must be the length of this wire? m (b) What must be the diameter of this wire?...
(S)A 20.0cm diameter circular loop of wire is placed in a 10T magnetic field with its plane perpendicular to the magnetic field. The field is applied outward. In 0.40s the loop is rotated until the perpendicular to the loop makes an angle of 30 0 with the field lines (20 credits) Calculate the magnetic flux through the loop when its...
Circular motion, vertical surface with kinetic friction: A small block of mass 2.0 kg slides on a horizontal frictionless surface as it travels around the inside of a hoop of radius R 0.50 m. A view from above is shown. The coefficient of friction between the block and the hoop wall is 0.20. Therefore, the block is slowing down. a)...
