Answer:
The force of the finger causes the books to accelerate and fall.
Explanation:
Solving this using the time, we know that range = horizontal velocity x time of flight
<span>since there are no horizontal forces acting on the ball, there are no horizontal accelerations and the initial horizontal velocity of 36 cos 28 will be constant throughout. I</span><span>f we use the correct time of flight given the launch parameters, we have </span>
<span>range = 36 cos 28 x 3.44 s = 109.3 m </span>
Quantization is the concept that a physical quantity can have only certain discrete values. ... For example, matter is quantized because it is composed of individual particles that cannot be subdivided; it is not possible to have half an electron. Also, the energy levels of electrons in atoms are quantized...
Rather than continuous waves, light was coming in packets of energy which can be defined with its frequency and planck constant 'h' as we mentioned earlier and said 'so, the energy is quantized'. In the atomic world, energies are also quantized. This means it can have only certain values.
