How do landforms change as a result of earthquakes?

Answer:

One of the more important properties of sound is that its speed is nearly independent of frequency. ... Therefore, the relationship between f and λ is inverse: The higher the frequency, the shorter the wavelength of a sound wave. The speed of sound can change when sound travels from one medium to another.

Answer:

2.5

Explanation:

The equivalent resistance of the combination of the two same

resistors when connected in parallel is 0.4 ohms.

There are two types of connection of resistor-

          [tex]R_{eq}=R_1+R_2+....R_n[/tex]

        [tex]R_{eq}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....\dfrac{1}{R_n}[/tex]

A combination of two identical resistors connected in series has an equivalent resistance of 10 ohms. As these two resistor has the same resistance, say (R). Thus,

[tex]R_{eq}=R+R10=2R\\R=5\rm\; ohm[/tex]

Equivalent resistance, when connected in parallel, is,

[tex]R_{eq}=\dfrac{1}{R}+\dfrac{1}{R}\\R_{eq}=\dfrac{1}{5}+\dfrac{1}{5}\\R_{eq}=\dfrac{2}{5}\\R_{eq}=0.4\rm\; ohm[/tex]

The equivalent resistance of the combination of the two same

resistors when connected in parallel is 0.4 ohms.

Answer:

There is an inverse relationship between distance and light intensity - as the distance increases, light intensity decreases. This is because as the distance away from a light source increases,..

Explanation:

The light intensity decreases as magnification increases. There is a fixed amount of light per area, and when you increase the magnification of an area, you look at a smaller area. So you see less light, and the image appears dimmer. Image brightness is inversely proportional to the magnification squared.

Answer:

he string has POTENTIAL ELASTIC energy

Explanation:

he catapult is a very good example of energy transformations.

Initially when the string is taut it has an elastic potential energy, when releasing the lever it is transformed into cinetic energy in the ball until it shoots out.

Consequently the string has POTENTIAL ELASTIC energy

Answer:

The answer is elastic

Explanation:

In positron emission, also called positive beta decay (β+-decay), a proton in the parent nucleus decays into a neutron that remains in the daughter nucleus, and the nucleus emits a neutrino and a positron, which is a positive particle like an ordinary electron in mass but of opposite charge.

= 120 kgm/s

Answer:

Solids: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

Answer:

do not require a medium

Explanation:

Light waves can be regarded as electromagnetic waves and it transverse in nature, no medium material is required to pass through. Light wave can travel through vacuum and it's ray can travel in straight lines even from point source. Light convey energy in perpendicular direction to electric field as well as magnetic field.

Answer:

By pointing one's right thumb along the direction of the current, the direction of the magnetic field can by found by curving one's fingers around the wire. The strength of the magnetic field depends on the current I in the wire and r, the distance from the wire.

Answer:

The (vertical) speed of the driver as he strikes the water is approximately 18.22 m/s

Explanation:

From the parameters given in the question, we have;

The time after which the driver strikes the water after he drives off a platform, t = 1.857 s

Let 'v' represent the vertical speed of the driver

We can find the vertical speed of the vehicle as it strikes the water as follows;

v = u + g·t

Where;

v = The final vertical velocity of the driver

u = The initial vertical speed of the driver = 0 m/s

g = The acceleration due to gravity ≈ 9.81 m/s²

t = The time of motion = 1.857 seconds

Therefore, we have;

v = 0 + 9.81 m/s² × 1.857 s = 18.21717 m/s

Therefore;

The vertical speed of the driver as he strikes the water, v ≈ 18.22 m/s

Answer:

q = 240 C

Explanation:

The current passing through a circuit is defined as the amount of charge passing through that circuit per unit of time. Hence, the current can be calculated through the following formula:

[tex]I = \frac{q}{t}\\\\q = It[/tex]

where,

q = total amount of charge = ?

I = current = 2 A

t = time = 120 s

Therefore,

[tex]q = (2\ A)(120\ s)\\[/tex]

q = 240 C

Answer:D.Refractive Indez

Explanation:

It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".

You're going for "refractive index", but you've got the ratio flipped over.
