Answer:

D) 15s

Explanation:

let Te be the period of the block-spring system on earth and Tm be the period of the same system on the moon.let g1 be the gravitational acceleration on earth and g2 be the gravitational acceleration on the moon.

the period of a pendulum is given by:

T = 2π√(L/g)

so on earth:

Te = 2π√(L/g1)

     =  6s

on the moon;

Tm = 2π√(L/g2)

since g2 = 1/6 g1 then:

Tm = 2π√(L/(1/6×g1))

      = √(6)×2π√(L/(g1))

and 2π√(L/(g1)) = Te = 6s

Tm = (√(6))×6 = 14.7s ≈ 15s

Therefore, the period of the block-spring system on the moon is 15s.

Answer:

Good morning! It's D. all of the above

Explanation:

Social backgrounds, culture, politics, education and economic reasoning might equally contribute to uncontrolled settlements. People live in disaster-prone areas partly for economic reasons. In the case of Semarang, where tidal flooding submerges houses, people stay due to economic factors.

1. What type of interference is happening when intersecting light waves subtract from each other to create dark spots? Which let
user100 [1]

Answer:

1. The type of interference happening when intersecting light waves subtract from each other to create dark spots is known as destructive interference

Destructive interference happens when the positive displacement or crest of one wave is cancelled by the negative displacement, or through of another wave of the same frequency resulting in a wave with lower amplitude

The letter on the diagram that shows destructive interference is the letter "c"

2. When particles pass translate through a key hole, they do not interfere with each. Therefore, when light is considered as a stream of particles, when it passes through a keyhole, there will be no  interference, and the light will particles will not interact with other light particles such that the pattern formed on on a wall on the other where the particles impinge on will be the shape of the single slit or keyhole

3. Three behaviors of light that support the theory that light travels in waves includes;

a) Refraction

b) Interference

c) Diffraction

Refraction

Refraction describes the change in velocity of light when it travels from one medium to another of different density, in which the light changes its speed

Interference

Interference is the superposition of two or more waves with the addition of the wave displacements resulting in a wave of larger or lesser amplitude than each of the individual waves

Diffraction

Diffraction is defined as the tendency of light to bend or spread when it goes past an object placed in its path by passing around the objects edge

4. The properties of a blackbody radiator includes;

1) A blackbody radiator absorbs all electromagnetic radiation incident on it

2) A blackbody radiator is capable of emitting black-body radiation

3) The peak of the emitted radiation depends on the blackbody temperature

4) The length of the wavelength of the peak radiation is inversely proportional to the temperature of the blackbody

5) The blackbody has zero coefficient of reflection or transmission and therefore, it does not reflect incident heat or light which makes it black

An example of a blackbody radiator is a burglar alarm that flashes light when there is an incident but cannot be ordinarily seen because of its dark color which is meant to absorb all incoming light

Explanation:

Wave interference is the phenomenon which describes the effect of the coming together or superposition of two or more waves to result in a wave displacement at a given point that is either reinforced (larger), cancelled (lower) amplitudes or the waves may have their original amplitudes when there is no interference

The wave displacement for the waves coming from the same source are taken as vectors from which the combination is calculated by using vector addition.

Why are isotopes not shown on the periodic table
Fofino [41]

Hey there!

The periodic table is arranged by number of protons/electrons which is the same for all isotopes of an element. <u>A different isotope will have a different number of neutrons only, which does not qualify it for a separate space on the periodic table.</u>

I hope this helps!
