A lossless transmission line of 50 ohms impedance is connected to a resistive load of 80 ohms. Find the reflection coefficient (defined in terms of voltages), the standing wave ratio and the input impedance of the line assuming the length of line as a) one-quarter wavelength and b) one-half wavelength. Comment on the result you found in the latter.

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.

Boiling water is an example of physical change. true or false
