Pavel [41]

Answer:a means of solving a problem or dealing with a difficult situation.

Explanation:Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. Let's make use of our salt water example to talk about the two main parts of a solution.

A wave has a frequency of 50 hertz and a wavelength of 10m. What is the speed of the wave?
Sedbober [7]

Heya!!

For calculate speed of the wave, lets applicate formula:

                                                     \boxed{v=f* \lambda}

                                                   <u>Δ   Being   Δ</u>

                                             f = Frequency = 50 Hz

                                                 v = Velocity = ?

                                           \lambda = Wavelenght = 10 m

⇒ Let's replace according the formula:

\boxed{v = 50\ Hz * 10\ m }

⇒ Resolving

\boxed{v= 500\ m/s}

Result:

The speed of that wave is <u>500 meters per second.</u>

Good Luck!!

A 4kg brick is dropped from the top of a building whose hight is 30m.what is the velocity with which it reaches the ground​
miss Akunina [59]

Answer:

=24.25 ^−1

Explanation:

Let   and   be initial and final velocity of the body respectively,  

be acceleration due to gravity ( 9.8^−2 ),  ℎ be the height of the body.

=0 ^ −1

ℎ=30

we know that, ^2−^ 2=2ℎ

^2=2∗9.8∗30

^2=588

=24.25 ^−1
