Yes at the start the gradient is the same... At 0... But as soon as it leaves rhe origin the gradient will be steeper as water has leaked?
Yes the gradient will decrease to a greater extent, because F=ma tells us that because the resultant force will be greater and m will be lower the acceleration acting on it would be greater than the other truck at the same time.
What did people put for the oscilloscope.....why they put them in unit 2 i have no idea....im jsed to describing fringe patterns not bloody amplitdues!!!!
The grating question....did you see the blue light first?
Violet because the lower wavelength would be seen first because sin(theta) is proportional to wavelength , so the smaller wavelength (violet) would have a smaller value of sin(theta )and therefore a smaller value of theta so you would see it first.

This was there single slit diffraction question , i just said the reasons why AB would get smaller (closer) , a smaller width
It must be either red or violet because they are at either end of the visible spectrum. I just don't have a clue which.
Pretty sure it was violet since fringe spacing = (lambda x distance)/s so the smaller the wavelength the smaller the fringe spacing, so you would see the smallest wavelength first which is violet
For the support force i got 196N Show 12ms-1 = 11.831....ms-1 Work out horizontal speed = 10.9ms-1 A few other answers I got: 7.3 15.6 0.21ms-2 3.3ms-1 0.18J
