High schools in which the completion rate is consistently 40 percent or less are known as _______.

An elevator car (Fig. Below) has a mass of 1000 kg and is carrying passengers having 200 kg altogether. A constant friction force of 400 N retards its motion.  Find power delivered by the elevator if it is moving up with constant velocity of 10 m/s. qr.png

Three forces, F1 = 80.0 N, F2 = 160.0 N, and F3 = 40.0 N act on an object with a mass of 2.00 Kg which can move along a frictionless inclined plane as shown in the figure. The questions refer to the instant when the object has moved through a distance of 0.600 m along the surface of the inclined plane in the upward direction. Calculate the amount of work done by F1,F2,F3. picture.PNG

An 8.0-g bullet is shot into a 4.0-kg block, at rest on a frictionless horizontal surface (see the figure). The bullet remains lodged in the block. The block moves into an ideal massless spring and compresses it by 8.7 cm. The spring constant of the spring is 2400 N/m. qq.jpg What is the initial velocity of the bullet/block system, when the block and the system move with same velocity  ( the initial velocity of the block with captured bullet)?

A force on an object is given by F(x) = ( -4.00 N/m)x + ( 2.00 N/m3)x3. What is the change in potential energy in moving from  x= 1.00  to  x=2.00 m?

Edwin Sutherland’s differential association theory states that _______.

List 4 categories of clinical manifestations of CNS dysfunction. 

All of the following family factors are associated with delinquency except _______.

A 6.00-kg ornament is held at rest by two light wires that form 30° angles with the vertical, as shown in the figure.  An external force of magnitude F acts vertically downward on the ornament.  The tension exerted by each of the two wires is denoted by T. A free-body diagram, showing the four forces that act on the box, is shown in the figure. Using the Convention, Right (+),  Left (-), Up (+), Down (-) pic.jpg Total Vertical Force is equal to  (T, W, F are magnitude of the corresponding forces, θ= 30 0 )
