The volume of the sphere is given by V = 4/3 * pie * r^3. We seek dr/dt that the rate of change of the radius with respect to time.
V = 4/3 * pie * r^3
Since we know the rate at which the volume changes wrt time. We can plug it in to find dr/dt.
dV/dt = 36pie. But dV/dt = 4/3 * pie * 3r^2 * dr/dt
So we have that dr/dt = (dV/dt) / 4/3 * pie * 3r^2
So dr/dt = (36pie)/ 4/3 * pie * 3(4)^2
dr/dt = 113.112/ 201.0864 = 0.5624
Okay, i worked on this last year, a transverse wave is a wave that vibrates in the direction of its propagation, and a compression wave is a wave that travels closer together!
Because reliable conclusions are trustworthy and applicable.
Reliable is officially defined as being "able to be trusted to do or provide what is needed." and has been clearly shown in context of the first statement. Being interesting is not always a quality of something with reliability as what the second statement suggests. Also, reliable conclusions are always a part in scientific endeavor.
1. Current means flow of electrons and electrons are negative charged and so are attracted to the positive end of the battery and repelled by the negative end.
2. When battery is connected in a circuit that lets the electron flow through it, they flow from negative to positive.
3. When negative terminal of cell is connected to other negative terminal of the cell in a particular circuit then, current will not flow in circuit as electrons cannot flow from negative to negative terminal.
