Answer:
unchanged
Explanation:
The density of an object or of a substance is independent of the amount of substance. From the definition of density as mass per unit volume, the ratio of the mass of an object to the volume of the same object is always constant. The more the mass of the object, the more the volume, and vice-versa.
<u>Hence, if a brownie that measures 15 cm by 7 cm by 7cm and has a density of 2.3 g/cm^3 is cut into half, both the mass and the volume would change in equal proportion and the density would remain the same.</u>
Answer:
The correct statement should be The energies of electron are <em>quantized</em> when <em>they are bounded to an atom.</em>
In Quantum Mechanics The term Quantization used to measure the physical entities having certain discrete value. When we say energies of electron are <em>quantized</em> <em>that means it have some specific values</em> that are allowed, that is not continuous range of values.

Answer:
1 m/s
Explanation:
speed=wavelength*frequency
speed=0.5*2
speed=1
Answer:
60 mph (miles per hour)
Explanation:
0.5 hours is 1/2 of an hour, so to get the number of miles for a whole hour you multiply the miles ran by 2.
30 times 2 is 60.
