Answer:
Explanation:
This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.
Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.
The volume displaced here can be determined using the formula
Density of liquid = mass displaced ÷ volume
Hence, volume = mass displaced ÷ density of liquid
Answer:
look at it is the correct answer because if a new gas has formed bubbles will how or change of colour so look at it
Explanation:
Atoms are composed of electrons in a cloud around a positive nucleus.
Answer:
6.94 × 10^33Hz
Explanation:
E = hf
Where;
E = Energy of wave (J)
h = Planck's constant (6.626 × 10^-34J/s)
f = frequency (Hz)
According to the information provided in this question, the hypothetical energy of the wave is 4.6J
Hence, using E = hf
4.6 = 6.626 × 10^-34 × f
f = 4.6 / 6.626 × 10^-34
f = 0.694 × 10^34
f = 6.94 × 10^33Hz
Answer:
Mass number = 195
Explanation:
Isotope:
An atom of an element that contain same atomic number but different atomic mass.
The difference in atomic mass is due to the different number of neutrons present, but the number protons and electrons are remain same.
In given isotope of an atom there are 85 protons and 85 electrons while number of neutrons are 110.
The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral and when an atom loses its valance electron the number of protons increases and thus positive charge increased and atom form cation.
Mass number = number of protons + number of neutrons
Mass number = 85 + 110 = 195
