Dot Point 1.5.2 part (c) The diagram shows a horizontal 10cm square loop carrying 1.5 A in a magnetic field of strength 0.25T c) Predict the force on side AC of the loop if it was made into a coil with 50 turns. Side AC is 90 degrees to the magnetic field. I used F=lIB So F = 0.025 x 1.5 x...

A rocket has mass 400kg, 75% being fuel. It develops a thrust of 8000N. Calculate its initial acceleration. How do I do this?

Physics Dot Point 1.6.4 part (b) I don't understand how to do this. Heres the question: Satellite X has its orbit around Earth changed from an altitude of 10,000km to 20,000km. Satellite Y has its orbit around Earth changed from an altitude of 20,000km to 30,000km. Both satellites have a mass...

Integration Question How do I do this question??

2.7.3 Calculate the acceleration of a proton on an electric field of strength 4.0 x 10^-5. The charge on a proton is 1.6 x 10^-19 and its mass is 1.67 x 10^-27 I'm not sure how to do this question. Can someone please explain? The answer is 3832 m/s^2

Im not very good at redox reactions and I just wanted to make sure I done these right: Write the half-equations for these and label each as oxidation or reduction: 1. Zn + Cu^2+ --> Zn^2+ + Cu 2. Cl2 + 2I^- ---> I2 + 2CL^- 3. Mg + 2H^+ --> H2 + Mg^2+ Any help would be greatly appreciated.

Is listening to music while studying a good thing? I usually get a bit into the music too much and get distracted from work so I'm not sure. But anyone got any good recommendations for music? I listen to rock mostly.

I think that an online study group is a very good idea especially since most of your friends are doing a different subject or they are really busy. If anyone is interested I'll gladly help you. Here's the subjects Im studying: Maths Advance (2 units) Maths Extension 1 (1 unit) English Advance...

This is a maths question I'm having trouble ewith: f(x) = x^3 when x is larger than or equal to 3 = 5 when x is between 0 and 3 = x^2 - x + 2 when x is smaller than or equal to 0 Evaluate: f(-n^2) It says that the answer is n^4 + n^2 +2 but I have no idea why and I need an explanation. Any...
