Plane travels at a speed of 240km/h when there's no wind. Today there's wind velocity Plane travels at a speed of 240km/h when there's no wind. Today there's wind velocity of -3i -7j km/h. Speed of the wind is 7.62 km/h. What is the working out of the position vector required if the pane is...

How to solve this vector problem? another aeroplane can travel at a speed of 240km/h when there's no wind. Today there's a wind velocity of -3i -7j km/h. The speed of the wind is 7.62 km/h. Find the position vector required if the aeroplane is to end up due East of its starting position...

another aeroplane can travel at a speed of 240km/h when there's no wind. Today there's a wind velocity of -3i -7j km/h. The speed of the wind is 7.62 km/h. Find the position vector required if the aeroplane is to end up due East of its starting position. What would this look like in a diagram?

According to Jaques Charles's contributions, did his discoveries relating to the Hindenburg or gas valve contributed to the understanding of the nature of gases?

thanks :)

I have 10kg of a radioactive material, which appears to continuously decay at a rate of 100% per year. How much will I have after 3 years? Please explain. :) The answer is not zero. However, the overall answer is that there will be roughly .49....kg of material left after 3 years. Which...

What happens if Zn metal is dipped into ZnSO4 solution? Is Zn metal made up of zn 2+ ions and electrons?

Oh okay, i was worried about putting it in the wrong forum, what forum would be more suitable. Because i am trying to gather the unit scores for my atar estimate.

I know that for normal specialist class the lowest unit score was 60 % (not accounting the v grades) What is the lowest score for specialist extension then?

I got 80% on my chemistry test that was worth 30%. My Z score was 1.45. the mean was 56% and the sd was 13. Does the Z score of 1.45 pull the 80% higher? What roughly would I get for this chem test.

What type of chemical reaction is ? So2 + H20 to H2SO3?

Is C5H6N and C5H5NH the same ?

what is the conjugate acid of base C5H5N? Is it HC5H5N or C5H5NH? It seems to be the H plus ion is attached to the end instead of the front? why in this particular order?

what is similar about the seasons of antipodes? (countries opposite side of each other)

How do we find the focal length between the focus point and the directrix from vertex?

Sorry about that, the directrix is x= -1

oh yep just figured it out, its 75.34/17 x 8 which makes the 35.46 answer :DD

what is the Method of finding cartesian equation of this conic parabola. How do we find the vertex or the focal length? Given: focus at (-4,0) and directrix at -1
