Hi everyone, I'm conducting an experiment where I place a ferrous material rod inside a solenoid to measure it's temperature due to induction heating, as shown in the video below: The aim of my experiment is to calculate the magnetic field from the temperature of the ferrous material rod. Is...

Here is what I did: I found that the net of the cone are basically two rings (for the composite fiber) and a trapezium)for the curved surface. It is a three dimensional trapezium, so I multiplied the trapezium's area by the width (2.5cm). I subtracted the volume of the larger trapezium prism...

Yes, I have tried that, but that does not work either :(

Yes, thanks, I have realized that . The total height is 30m. However, I can't calculate the volume of fiber composite needed?

The required Formulas are: Area of circle = Pi (r)^2 Volume of Cone = 1/3 Pi (r)^2 h Here is my try: I know the smaller cone and bigger ones are congurent, so 50/25 = 15/h h=7.5, but the answer is incorrect. Please help

s = ut + (0.5*a)*(t^2) 0.99 = 1/2 * a * (0.41)^2 a = 11.78 m/s^2, Which is way "off" the multiple choice answers

Homework Statement [/B] Lucy is measuring the acceleration due to gravity in Melbourne by dropping a ball through a vertical distance 1.00 m and timing how long it takes. The ball starts at rest, and Lucy times its fall four times. The results are: 0.47 s, 0.42 s, 0.48 s and 0.41 s. The...

From the top of a cliff, which runs North-South, the angle of depression of a yacht, 200 m out to sea and due east of the observer is 20 degress. When the observer next looks at the yacht he notices it has sailed 150m parallel to the cliff. Find: The angle of depression of the yacht from the...
