They are great circles with circumferences equal to the circumference of the planet. The prime meridian is zero longitude originally chosen to start counting east and west from Greenwich England. The equator is zero latitude and latitude is measured north
You are welcome, good luck. Remember that speedometer and compass.
By the way km/h is a perfectly good way to specify speed. However once you get into calculating accelerations and stuff you will need to convert that to meters/second
the speed is 95 the velocity also has to specify direction Remember, for velocity you need speedometer AND compass. ACCELERATION is rate of Change of Velocity b
You are welcome.
Yes. speedometer the same, compass different.
You are welcome. I believe you get it.
Right! You are on a roll.
Good :) and acceleration can be + or -. Often if negative it is called de-acceleration but not by physicists :)
You are welcome. By the way if you have learned about "centripetal acceleration", that is acceleration with no speed change, just direction.
Speed is a scalar. You an measure it with a speedometer. BUT Velocity is a VECTOR. You need both the speedometer AND a compass. Acceleration is a vector, rate of change of Velocity THEREFORE If speed changes, that is Acceleration ALSO If direction changes,

you need 2 mols of H2 for every mol of O2 2 H2 + O2 -> 2 H2O or in this problem 4H2 + 2 O2 --> 4 H2O H2 is 2+16 = 18 grams/mol so 4 * 18 grams
did not check arithmetic but that is the right idea
few and far between.
multiply both sides of the equation by 5 5/5 = 1 4*5 = 20
we know 5*3 is 15 and two 15s is 30 so (5x-3)(5x-3) = 0 so 5x-3 = 0 x = 3/5 twice because both solutions are the same. That means the vertex of the parabola is on the x axis at x = 5
