A capillary tube 2mm in diameter is immerse in a beaker of mercury. The Mercury level inside the tube is found to be 0.5cm below the
level of the reservoir. Determine the contact angle
between the Mercury and the glass ( take surface tension of mercury = 0.4N/m and density of mercury=13.5*10³

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

At what time will the interfering waves have an amplitudeof zero?
