Briefly explain how neurons communicate with each other in the CNS.

Two blocks are connected by a string that goes over an ideal pulley as shown in the figure. Block A has a mass of 5.00 kg and can slide over a rough plane inclined 36.0° to the horizontal. Determine the coefficient of kinetic friction between block A and the plane if Block B has a mass of 7.00 kg and the system is accelerated with 2.47 m/s2. If, Block A has mass of 6 kg, Block B has the mass of 8 kg, acceleration of the system is 6.554 m/s2  with the coefficient of kinetic friction between block A and the plane is 0.15,  Which planet in the table below could be the experiment was performed on, why? ( Work on a piece of paper first, find the answer and start typing your answer here with detailed explanation of each steps (do not attach any picture! you must type the explanation here).  Without proper explanation, no credit will be given.Do not worry about the equations subscript or superscript, I just want to make sure you understood how you came up with the final answer.) For the coefficient of kinetic friction, you can type mu (I will understand ). pp qq.png  gg(1).png

Copy of A hockey puck having a mass of 0.30 kg slides on the frictionless, horizontal surface of an ice rink. Two hockey sticks strike thepuck simultaneously, exerting the forces on the puck shown in Figure below. The force F1 has a magnitude of 5.0 N, and the force S F2 has a magnitude of 8.0 N. HOCKY.png Magnitude and direction of the pucks total acceleration is :

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 potential energy stored in the spring after the spring is compressed by 8.7 cm?

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?

List the 2 different types of adipose tissue and their function.

block rests on an inclined as shown in figure,  angle of the slope is θ. The Force F is applied so that the block just starts (barely) moving upward. Answer the following Question. A1 and A2 as well as F1 and F2 are the component of Force A and Force F. Q PIC.png The weight of the object   and the friction force on  the object is represented by
