1 BTU mean 1 degree of F increased for 1 pound mass. Since the mass unit is in kg that means you need to convert it into pound. One metric ton means 1000kg and 1 kg mean 2.20462lb, then the water mass is: 1000kg x 2.20462lb/kg= 2204.62lb.
You are putting 110,000 btus of heat, so the calculation would be
Temperature increase= energy/mass = 110000btus/ 2204.62lb= 49.9 degree
Isaac Newton is famous for the three laws
By the work-energy theorem, the total work done on the mass by the spring is equal to the change in the mass's kinetic energy:
<em>W</em> = ∆<em>K</em>
and the work done by a spring with constant <em>k</em> as it gets compressed a distance <em>x</em> is -1/2 <em>kx</em> ²; the work it does is negative because the restoring force of the spring points opposite the direction in which it's getting compressed.
So we have
-1/2 <em>k</em> (0.15 m)² = 0 - 1/2 (2.0 kg) (3.0 m/s)²
Solve for <em>k</em> to get <em>k</em> = 800 N/m.
The largest possible displacement you can get by combining the two of them is if they're both in the SAME direction. You walk 3 meters, stop for a breath, then walk another 4 meters in the same direction as the first one. The resultant is 7 meters.
The smallest possible resultant is 1 meter, if the two displacements are in OPPOSITE directions. This time, you walk 4 meters, stop for a breath, then you TURN AROUND and walk 3 meters back in the direction you came from. You end up 1 meter from where you started.
False. Energy in any form is a scalar quantity.
