We really don't know for sure, because there's no picture or description
of the cart and you haven't told us anything about it.
But we do know that fan speeds and accelerations are easy to change,
but the mass of things doesn't change.
So I'm pretty sure that it must be the mass of the cart that doesn't change.
Okay, let’s look at it this way: when does a line pass through the origin? The line represents possible values of x and y that satisfy the equation.
So, when a line passes through the origin, it passes through the coordinates (0,0). x = 0, y = 0. So, let’s model this with the equation ax + by + c = 0. Sub in x = 0 and y = 0 to the equation and we find that 0 + 0 + c = 0. Clearly, c = 0.
So, with this simple explanation, I hope you understand when a line does pass through the origin.
Now, let’s look at when a line doesn’t pass through the origin. This is when c is not equal to 0. Hence, when x = 0, y cannot equal 0; c + by = 0, and we know that c is not 0. If y is 0, then we get c = 0… where c is not 0. Ehh. Thus, you can see that a line does not pass through the origin when c is not equal to 0 by ehat is hope is a simple explanation. You don’t need to know how to prove it, I presume, but that’s not too hard either.
Oops, I realised that I just assumed you were talking about linear graphs. For quadratic graphs, the reasoning is similar. For graphs of the form y = ax^2, the minimum/maximum point of the graph will be the origin. For graphs of the form y = ax^2 + bx, it will pass through the origin but the line of symmetry will be different. For graphs of the form y = ax^2 + bx + c (you know, where c is not zero) , the graph will not pass through the origin because the maximum/ minimum point is actually raised or lowered by c units
Answer:
2
Explanation:
since the second object was in it stationary, it velocity is 0 m/s
The equation for finding density is Mass divided by volume.
41/8=5.125 grams per cubic meter.
Answer: The answer is "C"
Explanation:
The electromagnetic waves are arranged in the increasing wavelength and energy by the following order;
Radio waves has the lowest energy and wavelength but of the highest frequency.
The Infra-red rays follows the visible light follows, the ultraviolet ray follows, the X-ray follows and then the Gamma-ray has the highest energy and wavelength but the lowest frequency.
Therefore the answer is C, radio, infra, visible, ultraviolet, x-ray, gamma.
