A .500 kilogram cart traveling to the right of a horizontal frictionless surface at 2.20 meters per second collides head on with a .800 kilogram cart moving to the left at 1.10 meters per second. what is the magnitude of the totak momentum of the twi cart systemafter the collision?

it takes about 30 days for it to break down

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.

no

sodium is solid at rt

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
