A resistor dissipates 2.00 W when the rms voltage of the emf is 15.0 V. At what rms voltage will the resistor dissipate 14.0 W?

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

a and c

c is 100% but i am confused in a

the total distance traveled by the car is

30km + 49km = 79 km .

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
