Answer:
Subtract the atomic number from the mass number
Explanation:
The number of neurons in an atom is equal to the difference between the atomic number and the mass number
Answer:
Magnetism is a physical phenomenon that manifests itself in a force acting between magnets or other magnetized or magnetisable objects, and a force acting on moving electric charges, such as in current-carrying cables. The force action takes place by means of a magnetic field, which is generated by the objects themselves or otherwise. There are natural and artificial magnets. All magnets have two poles called the north pole and the south pole. The north pole of one magnet repels the north pole of another magnet and attracts the south pole of another magnet; the same with south poles.
Answer: 50 gram superball that strikes the wall at 1 m/s and bounces away at 0.8 m/s has greater change in kinetic energy.
Explanation:
50 gram superball that strikes the wall at 1 m/s and bounces away at 0.8 m/s has the greater change in kinetic energy because the collision is elastic in nature that is bodies separates after collision and doesn't lose any kinetic energy.
Also for an elastic collision, both the momentum and energy of the bodies are conserved compare to inelastic collision where only momentum is conserved but not the kinetic energy(this is attributed to bodies that sticks together after collision).
The amount of energy transferred to an appliance is depends on its power and length of time it is switched on. The wires attached to the appliance conduct the electricity and send it to the main motor function.
Answer:
9800 J
Explanation:
P.E = mgh
- m = mass
- g = gravitational acceleration
- h = height
P.E = (10.0)(9.8)(100) = 9800 J
