<span>Molecular mass of C is: 12.01 g/mol
1 mole C: 0.012 kg
Molecular mass of H is: 1.08 g/mol
1 mole H: 0.01 kg
Reduced mass: Mr = m1m2/(m1+m2) = 0.012*0.01/(0.022) = 5.45x10-³ kg
f = (1/2π)√(k/Mr) = (1/2π)√{500/5.45x10-³} = (1/2π)10²√{9.166} = 48.1 Hz. I hope this helps </span>
The woman is correct because it is the pace he is moving not walking.
The first blank: HEAT
The second blank: ELECTRICAL
The constant in Newton's law of gravitation relating gravity to the masses and separation of particles, equal to 6.67 × 10-11N m2 kg-2.
Answer:
The objects will stick together and move with common final velocity.
Explanation:
In an isolated system, there are no external forces acting on the object. Let there are two objects say object A and B. It is supposed that an isolated system in which two objects about to collide have equal and opposite momenta.
In an inelastic collision, the momentum of the objects after the collision remains while the kinetic energy is not conserved. Some of the energy is lost. After the collision, the objects will stick together and move with one common velocity.
Hence, the correct option is (b) "The objects will stick together and move with common final velocity".
