I'm such a devoted NASCAR fan that I don't even know if the starting line and finish line at Indy are the same line ... or maybe they're in different places, like the 100-meter sprint in track.
I have no idea, but I'm going to guess that the start and finish at Indy are the SAME line.
If that's true, then the displacement of a car that runs the whole 500 miles is very close to <em>ZERO</em>.
Displacement is the distance and direction between the place where the object starts out and the place where it ends up. The route it follows to get from the start to the finish is completely ignored, and doesn't matter.
(Do they the Indianapolis 500 in "stock" cars ? ?)
You need to have the exact amount of atomic number and mass number on each side of the arrow. on the left of the equation Ra has 226 mass and 88 atomic. on the right the He with the atomic number of 2 and the mass number of 4. you’d minus the atomic number on the left with the atomic number on the right (88-2) getting 86 and minus the mass number on the left with the mass number on the right (226-2) which is 224
this means that A = 224 and B = 86
Answer:
a. 0.01 C
b. dissipated to outside environment
Explanation:
Let the specific heat of copper be 0.3846 kJ/kg-K or 384.6 J/kg-C
(a)The original kinetic energy of the block is:
As 85% of this kinetic energy is converted to block internal heat energy, with specific heat we can calculate the rise in temperature:
(b) the remaining 15% energy would probably be dissipated to outside environment as heat energy
As kinetic energy increases, substance temperature increases
Answer:
The relation between F1 and F2 is : F1 = - F2. That is the forces are equal in magnitude but opposite in direction.
Explanation:
- According to Newton's 3rd law of motion statement, it states that for all actions there is equal but opposite reaction.
- This law is also known as the law of symmetry. It means that forces occur in pairs in any conditions. An object will not apply force on other object without experiencing the force on itself.
- This means when an object exerts force F1 on another object, it also exerts the same force of same magnitude on itself in opposite direction to the force it exerted on another object.
