Here, "Wavelength is same for both waves" it is the distance between two crests or two consecutive troughs, so, it is constant for both of them, you can easily figure it out.

In short, Your Answer would be "Wavelength"

Hope this helps!

IRISSAK [1]

Ans: Alcohol addiction occurs when the desire to feel good and have the pleasurable feelings associated with alcohol or other drug drives desire to continue using the substances.
This is because when a person consumes alcohol on a daily basis, that person then becomes dependent on alcohol and then in every mood of happiness or anxiety, he/she has a strong desire of consuming alcohol and feel good after consuming it.

if 130N centripetal force is needed to keep a 0.45kg ball that is attached to a string that is 0.7m long to complete 5 full rota

andrezito [222]

Answer:

centripetal acceleration of the ball is 6.9 m/s/s

tangential speed of the ball is 2.2 m/s

Explanation:

As we know that ball complete 5 rotations in 10 seconds

so frequency of rotation of ball is given as

$f = \frac{5}{10} = 0.5 Hz$

now we know that angular frequency is given as

$\omega = 2\pi f$

$\omega = 2(\pi)(0.5)$

$\omega = \pi rad/s$

Now centripetal acceleration is given as

$a_c = \omega^2 R$

$a_c = \pi^2 (0.7)$

$a_c = 6.9 m/s^2$

now the velocity of the ball at this angular frequency is given as

$v = R\omega$

$v = 0.7 (\pi)$

$v = 2.2 m/s$

The side length of a square is modeled by s=A, where A is the area of the square. Graph the function. What is the side length of

Naya [18.7K]

Answer:

√35 square units

Explanation:

Area of square = 35square units

Formula of area of square is a =s*s where a is area and s is side

So,

s*s = 35

s^2= 35

s = √35

What is the difference between polarization and induction?

nalin [4]

In which it is the plane in which charges move. for example in electromagnetic waves polarization means the plane in which electrons oscillate. ... it is the distribution of electric charges (electron) in an object. induction of charges takes place in some insulators just by some mechanical interaction such as rubbing

Someone please help with this

SSSSS [86.1K]

Answer:

The new force is 2/3 of the original force

Explanation:

Coulomb's Law

The electrical force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between the two objects.

Written as a formula:

$\displaystyle F=k\frac{q_1q_2}{d^2}$
