What is energy in general?

The 0.5-kg collar C starts from rest at A and slides with negligible friction on the fixed rod in the vertical plane. Determine the velocity v with which the collar strikes end B when acted upon by the 5-N force, which is constant in direction.

A convenient and cost-effective way to store biogas is to use light-weight, rigid gas containers. The pressure and temperature of biogas stored in a 10 m^3 container are 1.5 bar and 5°C, respectively, as measured at an early morning time (state 1).

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A 13-L kerosene tank (ρ = 820 kg/m3) is filled with a 2-cm-diameter hose equipped with a 1.5-cm-diameter nozzle meter. If it takes 18 s to fill the tank, determine the pressure difference indicated by the nozzle meter.

Water at 400 kPa with a quality of 75% has its pressure raised 200 kPa (to 600 kPa) in a constant volume process. What is the new state (X, T) ? At what pressure does the water go into the single phase region.

List two characteristics of computers.

Which of the following elements of the CIA triad refers to maintaining and assuring the accuracy of data over its life-cycle? Confidentiality Integrity Availability Authentication

According to the video, what are some of the effects of the increase in the use of automated tools for Loading Machine Operators? Check all that apply.

A gas flows through a one-inlet, one-exit control volume operating at steady state. Heat transfer at the rate takes place only at a location on the boundary where the temperature is Tb.

An uncharged capacitor and a resistor are connected in series to a source of voltage. If the voltage = 7.41 Volts, C = 11.5 µFarad, and R = 89.
