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

QveST [7]

We have thatThe options that define Speed, Velocity,Acceleration.

  • Speed is used to describe how fast the object is moving.
  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.

Options

B,D,E

From the question we are told

Choose the correct definitions of speed, velocity, and acceleration. Check all that apply.

  • Acceleration tells us in which direction the object is going. Speed is the rate of change of velocity in time.
  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe changes in the movement direction of the object. Acceleration tells us how far the object will go in a certain amount of time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.
  • Speed is used to describe how fast the object is moving.
  • Velocity is the rate of change of speed in time.

Speed is used to describe how fast the object is moving and tells us in which direction it is going.

Generally

  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.
  • Speed is used to describe how fast the object is moving without its direction in consideration

Hence

The options that define Speed, Velocity,Acceleration.

  • Speed is used to describe how fast the object is moving.
  • Acceleration is the rate of change of velocity in time.
  • Velocity is used to describe how fast the object is moving and tells us in which direction it is going.

Options

B,D,E

4. The Mariana trench is in the Pacific Ocean and has a depth of approximately 11,000 m. The density of seawater is approximatel
Alex73 [517]

Explanation:

It is known that relation between pressure and density is as follows.

            P = \rho gh

where,    P = pressure

     \rho = density

            g = acceleration due to gravity

            h = height

Putting the given values into the above formula as follows.

              P = \rho gh

                 = 1025 \times 9.8 \times 11000

                 = 110495000 Pa

Now, relation between pressure and force is as follows.

                P = \frac{F}{A}

or,            F = PA

                F = 110495000 \times \pi \times (0.1)^{2}

                   = 3.47 \times 10^{6} N

Thus, we can conclude that a force of 3.47 \times 10^{6} N can be  experienced at such depth.
