A 13-kg sled is moving at a speed of 3.0 m/s. At which of the following speed will the sled have twice as much kinetic energy?
<span>4.2 m/s</span>
Answer:
This is because, the flywheel has a very large moment of Inertia and hence sudden piston torques have negligible effect on the flywheel, but every piston combined has a significant torque. This smoothens out the vibrations.
Explanation:
Reduce the amount of waste- whether this is light, heat or sound waste.
Reduce the amount of friction that the machine is making
Answer:
14 atoms
Explanation:
Number of atoms in Fe₂(CO₃)₃
An atom is the smallest indivisible particle that takes part in a chemical reaction.
In Fe₂(CO₃)₃; we have:
Elements Number of atoms
Fe 2
C 3
O 3(3) = 9
Total number of atoms = 2 + 3 + 9 = 14 atoms
