Ok, Brainly doesn't have the required math symbols I need to give you the best looking answer so we'll have to do this the best we can. In short, yes it could be a wave. A simple wave,ψ, is described by the equation
d²ψ/dx² - (1/c²)d²ψ/dt² = 0. The right side must be a nonzero constant, which is zero here. This is a basic wave equation. It says if the second partial derivative of a function with respect to space minus the second partial derivative of that function with respect to time, multiplied by a constant (1/c² here) equals a constant (0 here) then that function describes a wave. Brainly doesn't have a partial derivative symbol so I used "d". Also the c in my equation is the speed of the wave. Not necessarily the same c as in your equation.
Now let's look at your function. The second partial derivative of it with respect to x makes the t term 0 (it's a constant as far as x is concerned) and the x term becomes 2c. Doing the same thing for the partial derivative of it for t leaves 2d. These terms represent two constants, which if subtracted, as the wave equation requires, would lead to a constant on the right, which could be made zero if the coefficients c and d are chosen correctly.

Because both the elements are non-metals
Answer:
<em>The flux through the sphere will remain the same, and the magnitude of the electric field will increase by four times.</em>
Explanation:
The electric flux is the number of electric field, passing through a given area. It is proportional to the electric field strength and the area through which this field passes.
If the radius of the sphere is halved, the area of the sphere will reduce by square of the reduction, which will be four times. The electric field lines will become closer together, or technically increase by a fourth of its initial value. The resultant effect is that the electric flux will remain the same.
If originally,
Φ = EA cos∅
where Φ is the electric flux through the sphere
E is the electric field on the sphere
A is the area of the sphere.
If the area of the sphere is reduced to half, then,
the area reduces to A/4,
and the electric field increases to be 4E on the sphere.
The flux now becomes
Φ = 4E x A/4 cos∅
which reduces to
Φ = EA cos∅
which is the initial electric flux on the sphere.
