The approximate de Broglie wavelength of a tennis ball is 9.4×10^(-34) m.
What is the de Broglie wavelength:
It is the wavelength that is associated with an object in relation to its momentum and mass is known as de Broglie wavelength.
A particle's de Broglie wavelength is usually inversely proportional to its force.
The formula of de Broglie wavelength:
here mass of a tennis ball is given
mass, m=70 g = 0.07 kg
ball is moving with velocity
v = 10 m/s
h is Plank constant,
h=6.63×10^(-34) Js
substituting the values in formula,
λ = 6.63×10^(-34) / ( 0.070*10)
λ = 9.4 ×10^(-34) m
Hence
The approximate de Broglie wavelength of a tennis ball is 9.4×10^(-34) m

Answer:
purchasing bonds in order to increase the money supply.
Explanation:
The Federal Reserve raises or lowers interest rates through its regularly scheduled Federal Open Market Committee. That's the monetary policy arm of the Federal Reserve Banking System.
The Fed can attempt to increase the federal funds rate by selling Treasury bills, which decreases bank reserves.
Convection, because it is the process of heat transfer from one location to the next by the movement of fluids. The moving fluid carries energy within it.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are clean energy sources and should replace fossil fuels.
Carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases.
<h3>What is a carbon footprint?</h3>
A carbon footprint is the measure of the total amount of greenhouse gases that are emitted into the atmosphere each year by an individual.
Greenhouse gases are responsible for global warming.
For an individual to reduce his or her carbon footprint, they can:
- Reduce the use of automobile
- switch other renewable energy sources like solar energy
Hydrogen fuels are able to replace fossil fuels as they are clean energy sources.
An individual's carbon footprint should be regulated by law in order to reduce the amount of greenhouse gases released.
In conclusion, greenhouse gases are responsible for global warming.
