Answer:

Speed of gamma rays = 3 x 10⁸ m/s

Explanation:

Given:

Frequency of gamma ray = 3 x 10¹⁹ Hz

Wavelength of gamma rays = 1 x 10⁻¹¹ meter

Find:

Speed of gamma rays

Computation:

Velocity = Frequency x wavelength

Speed of gamma rays = Frequency of gamma ray x Wavelength of gamma rays

Speed of gamma rays = [3 x 10¹⁹][1 x 10⁻¹¹]

Speed of gamma rays = 3 x [10¹⁹⁻¹¹]

Speed of gamma rays = 3 x [10⁸]

Speed of gamma rays = 3 x 10⁸ m/s

In what way could a random mutation provide an organism with an advantage? With a example please
saveliy_v [14]

Answer:

They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur. They increase an organism's changes of surviving or reproducing, so they are likely to become more common over time.

What is the relation between the direction of electric field and equipotential line at the same point
gavmur [86]

Answer:

The direction of electric field and equipotential line at the same point are always PERPENDICULAR TO THE ELECTRIC FIELD.

Explanation:

Equipotential surface is a three dimensional part of equipotential lines.

Equipotential lines are a type of contour lines that is use to trace lines that have the same altitude on the map and the altitude is the electric potential.

Equipotential lines are always perpendicular to electric potential because the lines creates three dimension equipotential surface.

Which two components must a vector quantity
Lemur [1.5K]

Answer:

d. Direction and magnitude

Explanation:

The two components of a vector are its magnitude and direction.

Magnitude is the quantity of the substance

Direction is the path.

  • Other quantities are called scalar quantities.
  • Scalar quantities have only magnitude but no direction.

Examples of vector quantities are velocity, displacement, acceleration.

If the electron is initially in the ground level, E1=0.625E[infinity]E1=0.625E[infinity], and absorbs a photon, what maximum wav
tekilochka [14]

Answer:

 λ = 3.1824 10-25 m

Explanation:

To release the electron from the power well the absorbed photon electro must be greater than or equal to the energy of the electron in the power well

           

The photon energy is E_photon = 0.625 J

The speed of light is

       c = λ f

         

Let's use Planck's equation

        E = h f

             

We substitute

       E = h c / λ

        λ = h c / E

        λ = 6.63 10-34 3 108 / 0.625

         λ = 3.1824 10-25 m

A zebra starts from rest and accelerates at 1.9 m/s, how far has the zebra gone after 5 seconds
Aliun [14]

Answer:

23.8 m

Explanation:

The distance travelled by the zebra can be calculated by using the equation:

d=ut+\frac{1}{2}at^2

where

u is the initial velocity

t is the time

a is the acceleration

For this zebra,

u = 0 since it starts from rest

a=1.9 m/s^2 is the acceleration

Substituting t = 5 s, we find the distance travelled by the zebra:

d=0+\frac{1}{2}(1.9)(5)^2=23.8 m
