You are in a large parking lot and you've lost your carl On your keys, you have a button to make your car honk its horn. You know that the
sound of your horn has a frequency of 350Hz and that the wavelength of
the sound waves is 0.25m. Being a bright and competent physics
student, you obviously open the timer and calculator apps on your phone
and perform a little experiment. If it takes 0.50 seconds for you to hear
the sound of your horn how far away is your car?

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.

if you answer my question i will answer yours

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
