Answer:

C. Crust, mantle, core

Explanation:

If you travel further into the earth's core, the density and pressure increases, along with temperature.

Explanation:

density increases as you travel from the crust to the inner core

the crust is on top

next is the mantle

and then the core

What is the fundamental frequency on a 8 m rope that is tied at both ends if the speed of the waves is 16 m/s?

lana [24]

Answer:

1 Hz

Explanation:

For rope fixed on both ends the length corresponds to λ/2 (λ is wavelength)\

Thus L = λ/2

=> λ = 16 m

We know that frequency and wavelength are related as

f x λ = v where f is frequency and v is speed of the wave

thus f = v/λ

f = 16/16 =1 Hz

Explain Newtons Laws

Vsevolod [243]

1) Newton first law of motion: state“If a body is at rest it reamain at rest and if it is in a motion it continu its motion unless a net external force acting on it”

This law also called law of inertia

2) Newton second law of motion: states that ‟acceleration to the force acting on the body and inversky proportional to the mass of the body”

3) Newton's third law of motion: It is not possible to exert a force abody with out the body exerting a forces in the opposite direction.

These forces are called action and reaction forces

hope it's helpful ❤❤❤❤❤❤

If you give it unbalanced force it would go up and if you can't give it enough it will stay a balanced force

Hello guys! Can you please help me with physics. I translated it in English. Can yall help me please how much you can!!

Alex777 [14]

Answer:

1. 60m

4. its speed is 20m/s . gravity is 10m/s . 20 ÷ 10 = 2 seconds after these 2 sec are over the velocity will be zero thus it would have fallen.

Explanation:

Am sorry these is what i could answer but i will try to research and get answers for the rest of the questions, hope this helps
