Answer:
Shown from explanation.
Explanation:
The resonant frequency is related by the formula;
Fo= 1/2π√(K/M)
Where Fo is resonant frequency
M is mass
K is the spring constant
From the expression above;
When K is increased frequency would increases since frequency is directly proportional to spring constant.
Similarly when the mass is increased the frequency decreases since frequency is inversely proportional to the mass.
Amplitude is a property of a wave and so the frequency stays same.
In order to keep the object moving in the same direction and with same speed, its initial and final momentum should be zero.
∴ Net force on the object should be zero.
protons and neutrons in the atom.
Explanation:
The mass number of an atom of carbon represents the total number of protons and neutrons in the atom.
Mass number = number of protons + number of neutrons.
- The mass of an atom is concentrated in the nucleus of the atom.
- The particles in the nucleus are called nucleons are they are made up of the protons and neutrons.
- Protons are positively charged.
- Neutrons carry no charges.
- Together, they make mass of atom.
- The mass of electrons are negligible

Answer:
![1446.7m](https://tex.z-dn.net/?f=1446.7m)
Explanation:
You need to look at this in 3 separate stages, and then sum thedistance from each stage:
Stage 1)
a=2
t=20
=0
![s=V_0t+\frac{1}{2}g t^2](https://tex.z-dn.net/?f=s%3DV_0t%2B%5Cfrac%7B1%7D%7B2%7Dg%20t%5E2)
![x=400m](https://tex.z-dn.net/?f=x%3D400m)
We also need to find the final velocity ![v=a*t=20*2=40m/s](https://tex.z-dn.net/?f=v%3Da%2At%3D20%2A2%3D40m%2Fs)
Stage 2)
a=0
v=40
t=20
![x=vt](https://tex.z-dn.net/?f=x%3Dvt)
![x=800m](https://tex.z-dn.net/?f=x%3D800m)
Stage 3)
a=-3
=40
=0
![v^=v_0^2 + 2 a x\\0=40^2+2*(-3)x\\x=266.7m](https://tex.z-dn.net/?f=v%5E%3Dv_0%5E2%20%2B%202%20a%20x%5C%5C0%3D40%5E2%2B2%2A%28-3%29x%5C%5Cx%3D266.7m)
So the total distance is ![x=400+800+266.7=1466.7m](https://tex.z-dn.net/?f=x%3D400%2B800%2B266.7%3D1466.7m)
Answer:The answer is because of the gravity and the mass formed in the sun, the magnetic field reacts to it and leaves a fault on earth. wind goes by the earth and procides to be ok
Explanation:that is it
