This part of the electromagnetic spectrum passes though lead and has the highest energy of all emissions. 1. gamma 2. X-ray 3. microwave 4. radio

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.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

real, smaller and upside-down.   so the answer should be b.

the answer for apex is the lowest
