For mach index of 0.6 what is the intake valve flow area g

Steam enters a counterflow heat exchanger operating at steady state at 0.07 MPa with a specific enthalpy of 2431.6 kJ/kg and exits at the same pressure as saturated liquid. The steam mass flow rate is 1.5 kg/min.

Discuss what in particular makes the light bulb a non-ohmic resistor. Specifically, how does temperature affect resistance? Can thermal expansion explain the non-ohmic behavior?

How can a machine make work easier for you? a. by decreasing the amount of work you do on an object b. by changing the direction of your applied force c. by increasing the the work done by the machine d. none of the above I think maybe a.

What happens to the acceleration of an object if the net force that acts on it triples in magnitude?

the acceleration of gravity is 28 times on sun than earth. Imagine there is a space suit that let you stand on sun. Calculate the weight of 100 kg person on earth in newtons

A force of 20 n acts upon a 5 kg block, calculate acceleration of the object

What resultant force is needed to accelerate a train of mass 3.41000000 kg from rest to 15.0ms in exactly 20s
