A uniform bar is 1.2 m and weighs 16 N. It is suspended by strings from the ceiling at the ends, labeled A and B. A block P weighing 96 N is attached at a position 0.30 m from A. Find the tensions in the strings at positions A and B.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

the force required to move the cart is divided by three or 33.33 n.

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.
