Answer:

the correct answer is D

Explanation:

Electromagnetic radiation is described by two equations, the first that gives the speed of light

        c = λ f

Where c is the speed of light, λ the wavelength and f the frequency

And the equation that gives the energy of the wave

         E = h f

In general, based on these two equations and their applications, the different areas of the electromagnetic spectrum have different names.  

The gamma radiation is in the high energy range, so it has a high frequency and if the frequency is high, the wavelength must be short. to keep the speed of light constant.

Based on the above, the correct answer is D

Li and Raj are playing football. They take turns trying to run past each other with the football. Li weighs 125 pound and Raj we
Elenna [48]

Answer:

Li has less mass and therefore less inertia, so he can change his motion more easily than Raj.

Explanation:

Inertia describes the resistance of an object to any change in its state of motion, and it depends on the mass of the object only. In particular:

- if an object has a large inertia (large mass), then it is more difficult to change its state of motion (i.e. to put it in motion, or to slow it down, or to change its direction of motion)

- if an object has small inertia (small mass), then it is more easy to change its state of motion

In this problem, Li has less mass than Raj, so he has less inertia, therefore he can change his motion more easily than Raj.

Which answer is a scientifically accurate description of velocity?
viktelen [127]

The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

Explanation:

Velocity is a physical quantity that describes the rate of change of displacement with time.

   Velocity = \frac{Displacement}{time taken}

The quantity differs from speed in that it has both magnitude and direction.

From the options given above:

Displacement: The boat traveled in the north direction from the dock to a 200m mark.

Time taken: approximately less than 5 minutes was the duration of traveling.

This describes the boat's velocity accurately.
