Answer:
It will sink.
Explanation:
Density of water=1gm/cc (In CGS)
Volume of cube=l^3 =3^3= 27cc
Mass of cube =54gm
Density of cube=M/V =54/27 =2gm/cc
Here, density of cube is greater than that of water. So, the cube sinks.
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
It is the LAST one in the options.
a balanced chemical equation occurs when the number of the atoms involved in the reactants side is equal to the number of atoms in the products side.
Sound waves are not a form of electromagnetic radiation
