The suspended 2.6 kg mass on the right is moving up, the 2.3 kg mass slides down the ramp, and the suspended 8.6 kg mass on the left is moving down. There is friction between the block and the ramp. The acceleration of gravity is 9.8 m/s 2 . The pulleys are massless and frictionless. What is the tension in the cord connected to the 8.6 kg block? Answer in units of N.

asthenosphere and convection

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

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
