B. the current in the circuit divides so that some flows through one component
many answers to this question so chose whatever you link:
- urbanisation -> more people, humanity keeps on living, more job opportunities etc
- source of income for farmers
- source for food (farming)
- source for trees (eg, to create wood (houses), or to use logs for fire)
The density of the metal cube is 2.703 g/cm³.
The mass of a metal cube is m =50.3 grams.
The edge length of the metal cube is l = 2.65 cm.
Now, the density (ρ) of a cube can be given as:
ρ = m/(a)³
Where (a)³ is the volume of the cube, m is the mass of the cube, ρ is the density of the cube, and a is the length of one side of the cube.
Since the sides of a cube are equal therefore the value of a is the same for each edge length of the cube.
Now, the density of the metal cube in g/cm³ is:
ρ = m / a³
ρ = m / l³
ρ = 50.3 g / (2.65 cm)³
ρ = 50.3 g / (2.65 cm)(2.65 cm)(2.65 cm)
ρ = 50.3 g / 18.609 cm³
ρ = 2.703 g/cm³

Answer:
11.6 s
Explanation:
We can use equation of motiom to solve this
The correct answer is C. microwaves, infrared, visible, gamma rays
Electromagnetic waves arranged in order of frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.
Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.
According to the Einsteins equation, E=hf, Energy is directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
