The cork in Question 1 travels I foot in moving from its lowest position to its highest position. What is the average velocity of the cork during this motion?

8ft/s

Explanation:

For computing the average velocity of the cork first we have to determine the frequency which is shown below:

= 4 Hz

Now the average velocity of the cork is

= 8ft/s

We simply applied the above formulas to determine the frequency and the velocity of the cork during this motion and the same is to be considered

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

where is the circuit diagram ?
