Solve these two maths showing the processes too in a well defined way. # A rigid tank contains 50 kg of saturated liquid water at 90 °C. Determine the pressure in thetank and the volume of the tank.# A cylinder-piston assembly initially contains water at 3 MPa and 300 °C. The water is cooled atconstant volume to 200 °C, then compressed isothermally to a final pressure of 2.5 MPa. Sketchthe process on a T-v diagram and find the specific volume at the 3 states.

In a nutshell, a smaller rock is propelled into the air as a huge counterweight in the back falls down, effectively converting gravitational potential energy into kinetic energy for the rock and the weight. But, since the rock is smaller.. it is propelled at a much faster velocity! Let's say we wanted to hurl a 50 kg boulder at a castle wall 100 meters away. Our wooden structure for the trebuchet is 10 meters tall, so that is the maximum distance the counterweight can fall. Assuming the launch angle is a perfect 45 degrees, and the boulder is released from ground level, derive the needed mass of the counterweight that will give the boulder enough kinetic energy to reach the base of the castle walls. You may assume no energy is "lost" due to friction, and ALL the counterweight's gravitational potential energy is converted into the boulder's kinetic enerqy. (HINT: You will need to employ 2D kinematics to find the needed final velocity, then use that final velocity in an energy equation…
A 50.0N weight uniform 4 metre long beam is hanging from a cord held out at a 30° angle as shown. And unknown weight not shown in the diagram is also hanging 1 m from the X on the diagram. A) The tension in the cord is measured with a spring balance and found to be 130 N. find the counter clockwise torque from the cord about the X shown in the diagram. B) balance torques to find the torque from the unknown weight that is not shown in the diagram Hint: add the unknown weight to the diagram and do not forget to include the weight of the beam in your calculation
