For any function f(x), f(-x) is always the reflection in the y-axis. However, some functions are symmetrical about the y-axis (i.e. show symmetry under reflection in the y-axis), the reflection f(-x) is the same as the original function f(x), so f(-x) = f(x) and you can say there is no...

In general, for f(x) = a(b - x)^(+/-n) + c, the negative in front of x indicates reflection in the y-axis. If n is even, a(- x)^(+/-n) is the reflection of a(x)^(+/-n) in the y-axis before the translations. But because a(- x)^(+/-n) = a(x)^(+/-n), the reflection is the same as the original...

An object has an acceleration to the right. Which one or more of the following statements is/are correct? A. The object could be moving to the right. B. The object could be moving to the left. C. The object could be moving upwards. D. The object could be moving downwards. E. The object could...

Then why copper and many other metals and non-metals are not attracted by magnets. By the way, physics is based on theories, not truths. :) :) :wave:

Implicit diff. of xy with respect to x yields y + xy'. :) :) :wave:

Derivative of a constant with respect to any variable is zero. You can think of derivative of a function as the gradient function of the function. If the function is constant, then its gradient must be zero. :) :) :wave:

Just wondering what type of questions that you were referring to. :) :) :wave:

Electric field strength at a point is the electric force (N) per unit charge (C) at that point. E = F/Q Magnetic field strength at a point is the maximum magnetic force (N) per unit length (m) of conducting wire carrying a unit (A) of electric current. B = F(max)/IL :) :) :wave:

It appears straight because you are looking at comparatively short distance (a small section of the graph). :) :) :wave:

(a) Work out the area under the graph from h = 4x10^5 to h = 6x10^5. This give you the work required for each kg of the satellite. :. total amount of work = area under graph x 800 (b) Use T^2/R^3 = t^2/r^3, where T period and R orbital radius of space shuttle, t period and r orbital radius...
