<h3>
Answer:</h3>
AgCl + NaNO₃
<h3>
Explanation:</h3>
- The reaction between silver nitrate and sodium chloride is an example of a double displacement reaction.
- In a double displacement reaction compounds or salts reacts and exchange cations or anions to form new compounds or salts.
- In this case, silver nitrate and sodium chloride exchange anions and cations to form silver chloride and sodium nitrate.
- Therefore, the complete reaction is given by;
AgNO3 + NaCl → AgCl + NaNO₃
- But since silver chloride is a precipitate, the reaction may also be an example of a precipitation reaction.
We are given with
M = mass of planet
R = radius of circular trajectory of the satellite
ms = mass of the station
mm = mass of the meteorite
ms = 10 mm
R/2 = new orbit distance
The speed of the meteorite can be solved using the law of conservation of momentum
ms vs + mm vm = (ms + mm) v
Since the new orbit distance is half the original
v = 2 vs
Substitute and solve for vs
Answer:
0.05J
Explanation:
Since the total energy is conserved I.e the mechanical energy, the energy present in the system are kinetic energy, potential energy and the gravitational potential energy. The expression for this energy is written as
Kinetic Energy=1/2MV^2
Potential Energy=1/2Kx^2
Where K is the spring constant and X is the extension the spring experience.
Gravitational Energy=mgh
Where m=mass, g=gravity constant and h=height
Hence for a spring with spring constant 10N/m and extension 0.1m the potential energy can be calculated as
PE=1/2Kx^2
If we substitute values we arrive at
PE=1/2×10×0.1^2
PE=0.05J

For an open ended pipe, the fundamental frequency is dependent on the length of the pipe and the speed of sound. Slightly less dramatic limiting factors are the temperature and pressure.
In an open pipe column, the fundamental frequency is f1 = V_sound / (2*L) which means that the longer the pipe, the lower the frequency.
Each frequency thereafter is just a multiple of the fundamental frequency.
f2 = 2* f1
f3 = 3 * f1
fn = n*f1
But that is not really what you are being asked. You are asked about the wavelength
Start with the fundamental formula
v = f wavelenght
f = n * v/2L
v = (n*v/2L) * wavelength The "v"s cancel out
2L / n = wavelength.

Fourteen
If the pipe increases in length, the frequency will go down and the wavelength will go up
