Create a multimedia presentation about the pros and cons of using fission as an energy source. 

A lab cart is moving on a straight horizontal frictionless track. The above graph of velocity versus time for the cart is given above. During some intervals a force is applied to the cart. Assume the cart has a mass of 0.5 kg. Rank the magnitude of the applied force for each of the following intervals.

is there a way you can send me the final exam review for NSC 306 J? FInals are coming up and I'm trying to study for it. 

In a refrigerant recycling system, R134a is purified using a simple distillation process in which a heating plate is submerged in a pressurized reservoir which boils and evaporates the R134a, as shown in the figure. This recycling unit is made up of a square-based reservoir with a side of 25 cm, a pipe and a level valve into which the refrigerant fluid is introduced and its level is maintained constant as the condensate is removed. The refrigerant vapor is condensed by a slightly inclined copper plate placed on the top of the device and collected in a tray. The copper plate is externally cooled by liquid water at 25°C that flows at 3m/s. Determine:

The saturation temperature and mass flow rate of refrigerant condensate for the heating plate power 500W;

Construct a graph of the saturation temperature and the mass flow rate of refrigerant condensate as a function of the heating plate power ranging from 100 W to 1000 W.

Can you explain the concept of momentum and its conservation in collisions?

Does the negative mass of antimatter mean that it's gravitationally repelled from stars?

Create a lab report determining how the variables in an electric circuit are related by Ohm's law 

that's for part C you could apply existing formulars. For part A and B could you derive and see the actual inertial using integral.

4) The book in the figure has the same shape as your physics textbook. About which axis is the

rotational inertia (a) the largest; (b) the smallest? You must justify your answer.

A projectile of mass 0.25 kg moving at 24.0 m/s collides with and sticks to a 1.75-kg block

that is connected to a spring for which k = 40.0 N/m, as in the figure below. The block is

initially on a frictionless part of a horizontal surface but starts to slide on a rough section immediately after the collision. If the maximum compression of the spring is 0.5 m, what is the force of friction on the block?

I need to show all work

1. Im ready to help you in physics.. Just inbox me please 

any one in need of help in physics studies?

Use dimensional analysis to obtain the SI unit of k in terms of fundamental quantities in the expression below. a is the acceleration, x is the displacement, m is the mass of the oscillating object, and k is the spring constant
