Answer:
last one.Condution and convection are equzlly efficentmethods of heat transfer.
Explanation:
Answer:
its an antique physics apparatus for demonstrating acoustic standing waves in a tube.
Work = (force) x (distance) = (450 N) x (4 m) = 1,800 joules
Power = (work) / (time) = (1,800 joules) / (2 sec) = 900 watts .
Answer:
Applied voltage should be 13.5396 kV
Explanation:
The charge stored by a capacitor when subjected to a potential difference 'v' across it's plates is given by

Solving for V we get

thus to store a charge of 0.11mC we solve for V as follows
Applying values we get
