1. floating water
2. they are equal
3.true
4.pushes back down with the force of 5n
Explanation:
Technically, they do have a skeleton. The hard shell it has is called an exoskeleton. It works just like our skeleton, in terms of muscles and support. And, it protects from harm, similar to the way our skin protects the inside of our body from dirt and such.
Hello!
Using Hooke's law, F spring=k delta x, find the distance a spring with an elastic constant of 4 N/cm will stretch if a 2 newton force is applied to it.
Data:
Hooke represented mathematically his theory with the equation:
F = K * Δx
On what:
F (elastic force) = 2 N
K (elastic constant) = 4 N/cm
Δx (deformation or elongation of the elastic medium or distance from a spring) = ?
Solving:




simplify by 2


Answer:
B.) 1/2 cm

There's an effect called The Doppler Effect, that's the "up and down" sound.
That frequency is 1.8mm and 115 per minute.
(Hope this helped.)
