i really need some clarification on this question it is doing my head in why i can't work it out, there is something that i am not taking into consideration but i don't know what it is please some help is required!
That is what i had done cross multiplied to get that equation?
Is the denominator then added to get 2x^2-7.9202 I'm oblivious of where to go from hear very lost atm?
ok,
Current = 1.99 m/s
Total time = 192 s
Total distance traveled = (2x153) = 306 m
I've used the total time taken taken (192s) to be equal to the formula for the time taken upstream and downstream which looked like this.
192 = (153/ (x + (-1.99)) + (153/(x + 1.99)
rearranging and...
A swimmer is training in a river. The current flows at 1.99 metres per second and the swimmer swims upstream a distance of 153 metres before swimming back to the starting point. If the total time for the swim is 192.0 seconds, what is the swimmer's speed relative to the water?
I've been stuck...
Points A,B and C are at the corners of an equilateral triangle of side 3 metres. equal positive charges of 2 micro-Coulombs are at A and B respectively. What is the potential at C??
Diffraction...need help bad
Suppose that a single slit diffraction pattern is displayed on a screen. The distance between the first minimum on the left of the screen and the first minimum on the right is 5.4mm. The screen is 0.9m from the slit and the wavlength of light is 546nm. Calculate the...
