You pull two blocks connected by a lightweight string across a horizontal table. Block 1 has a mass of 1.00 kg, and Block 2 has a mass of 2.00 kg. There is negligible friction between the blocks and the table. The string will break if the tension is greater than 6 N. What is the maximum pull that you can apply to Block 1 without breaking the string?

magnityde and direction

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

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.
