Answer:

D. shortest wavelength

Explanation:

Photons with the highest energy have the shortest wavelength. The shorter the wavelength, the higher the energy of a photon.

A photon is a quantity that transmits electromagnetic energy from one place to the other.

Gamma rays have photons that transmits the highest amount of energy.
The rays have the shortest wavelength and highest frequency of all electromagnetic radiations.

Energy, wavelength and frequency of a photon are connected using the expression:

E = h f = $\frac{hc}{wavelength}$

E is the energy

h is the Planck's constant

f is the frequency.

What characteristic does a good conductor possess?

zimovet [89]

A good conductor have lots of free electrons present in it As due to very less difference between valence band and conductive band so electrons can be easily available for conducting electricity

Ali is training for a marathon he knows he can run 12 miles in 114 minutes if he keeps this pace how long will it take him to ru

tigry1 [53]

Answer:

249.5 minutes

Explanation:

Ali's speed is given by:

$v=\frac{d}{t}$

where

d is the distance covered

t is the time taken

We know that he can run d = 12 mi in t = 114 min, so he can keep a speed of

$v=\frac{12 mi}{114 min}=0.105 mi/min$

The length of a maraton is

L = 26.2 miles

So we can find the time it takes for Ali to complete the marathon as follows

$t = \frac{L}{v}=\frac{26.2 mi}{0.105 mi/min}=249.5 min$

Use the accompanying seismogram to answer which of the three types of seismic waves reached the seismograph first.

UkoKoshka [18]

Answer:

Primary waves (P-waves)

Explanation:

Due to excess of the energy inside the earth when the tectonic plates begin to slide or fracture then the energy is released in the form of seismic waves, this causes the earthquake.

Two types of seismic waves are generally responsible for the earth quakes:

body waves
surface waves

Body waves are of two types:

Primary waves (P-waves)

These are the fastest of all the waves involved in the earth-quake which travel at a speed of 1.6 km to 8 km per second.

They can pass trough solids, liquids and gases. They arrive at the surface as an instant thud.

Secondary waves (S-waves)

They can only pass through the solids and they move slower than the P-waves.

As S-waves move, they displace the rock particles, pushing them outwards perpendicular to the wave-path that leads to the earthquake-related first rolling period.

Surface waves (L-waves/ long waves)

These waves move along the surface of the earth. They are responsible for the earthquake's carnage.

They move up and down the Earth's surface, rocking the foundations of man-made structures.

Surface waves are slowest of the three waves, which means that they are the last to arrive. So at the end of an earthquake usually comes the most powerful shaking.
