Two carts are at rest on a frictionless track, one twice as heavy as the other. they are acted upon by identical forces over the same time interval. which one has the greater final momentum after the force is removed?

like poles repel so keep pushing north to north and repels funny to see this

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
