A student performs a magic trick for their science classroom. They place clear Orbeezes inside a glass of water and the Orbeezes

seem to disappear. The student then pours out the water to reveal that the Orbeez are still inside the glass. What property of waves allows for this illusion to be successful?

Answer:

First off, these balls are, as implied by their name, made of a polymer

Explanation:

—a material with a repeating molecular structure (like plastic or even DNA)—that does a super good job of absorbing water.

It would be F only because I wouldn’t make sense CI doesn’t exhibit crystalline neither does BR so F

Metabolic activity in the human body releases approximately 1.0 x 104kJ of heat per day. Assuming the body is 50 kg of water, ho
Zarrin [17]

Answer:

The body temperature would rise by 47.85 °C

The  amount of water the body evaporates is  4.15 kg.

This makes sense because firstly the value obtained is positive  then secondly it is a normal occurrence in the real world that in a place where the temperature is high the body usually produce sweat in order to balance its internal temperature

Explanation:

Considering the relationship (between the heat released and the mass of the object)  as shown below

              q = msΔT    

where q is the heat released per day = 1.0 * 10^{4} kJ

              m is the mass of the body  = 50 kg

              ΔT  is the temperature rise = ?

               s is the specific heat  of water =  4,18kJ/kg^{o} C

              substituting values we have

                              1.0 * 10^{4} kJ  = (50kg) (4.18kJ/kg^{o}C ) ΔT

                              ΔT = \frac{1.0 * 10^{4}kg}{(50kg)(4.18kJ/kg^{o} C)}    

                                   =  47.85°C  

To maintain the normal  body temperature (98.6F = 37°C) the amount of heat released by metabolism activity must be utilized for evaporation of some amount of water

Hence

        Amount of water that must be evaporated =\frac{heat released per day}{heat of vaporization of water}

                                                                      = \frac{1.0* 10^{4}kJ}{2.41kJ/g} \\= 4149.38g\\=4.15kg  

          Note  (1 kg = 1000 g)

This makes sense because firstly the value obtained is positive  then secondly it is a normal occurrence in the real world that in a place where the temperature is high the body usually produce sweat in order to balance its internal temperature

Which of the following required Bohr's model of the atom to need modification ? A. Energies of electrons are quantized. B. Quant
ki77a [65]

Answer:

Electrons do not follow circular orbits around the nucleus

Explanation:

Bohr's model of the atom is a combination of elements of quantum theory and classical physics in approaching the problem of the hydrogen atom. According to Neils Bohr, stationary states exist in which the energy of the electron is constant. These stationary states were referred to as circular orbits which encompasses the nucleus of the atom. Each orbit is characterized by a principal quantum number (n). Energy is absorbed or emitted when an electron transits between stationary states in the atom.

Sommerfeld improved on Bohr's proposal by postulating that instead of considering the electron in circular orbits, electrons actually orbited around the nucleus in elliptical orbits, this became a significant improvement on Bohr's model of the atom until the wave mechanical model of Erwin Schrödinger was proposed.
