When the 200 g mass is placed on the pressure toadstool, the student measures how far the thin plastic block sinks into the sand and finds the depth to be 22 mm.
Describe how the student could use a thin wooden rod, a pencil and a 30 cm ruler to find an accurate value for
the depth​

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?

What is tan(61)? а. 1.80 b. 0.49 c. 0.61 d. 0.87

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) =_
