Let's find the relationship

$\\ \rm\Rrightarrow E=h\nu$

$\\ \rm\Rrightarrow \lambda=\dfrac{c}{\nu}$

So if frequency increases Energy of the wave increases and wavelength decreases and vice-versa

What is a vector?

nalin [4]

Answer:

C. A quantity with magnitude and a direction.

Explanation:

A vector can be defined as a quantity with magnitude and direction. Some examples of vector quantities are velocity, position, displacement, force, torque, acceleration.

For example, given the following data;

Time, t = 18.5secs

Final velocity = 78m/s

Initial velocity = 0

Substituting into the equation;

$a = \frac{78 - 0}{18.5}$

$a = \frac{78}{18.5}$

Acceleration, a = 4.22m/s²

Therefore, the acceleration of the object is 4.22m/s² due North.

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

$Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}$

$a = \frac{v - u}{t}$

Where,

a is acceleration measured in $ms^{-2}$

v and u is final and initial velocity respectively, measured in $ms^{-1}$

t is time measured in seconds.

How is an electric field similar to a gravitational field?

kap26 [50]

They both-
1) are vector fields
2) they both transmit forces between objects

I hope this helps :))

Lerok [7]

The best option for visually representing how one part of data relates to a whole would likely be a circle graph. This will allow for the entirety of a data set to be seen at once, as well as providing an easy way to compare and contrast the different parts and how they relate to one another.

Your friend says that for a moving object to continue moving, a force must be continually applied to it. Do you agree with your

Zigmanuir [339]

Answer:

I would disagree with my friend because that according to Newton's first law, an object in motion will continue to be in motion until stopped by another object/force. If the object is already moving, it will stay in motion until something else stops it. There is no need for a force to be <em>continually</em> applied to it while it's already moving.
