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.
Answer: b. infrared
Explanation:
The visible light with the smaller frequency is associated with the color red.
While the blue is the one with the larger frequency.
Now, as the name says, infrared waves are the ones with a frequency just below the one of the red visible light.
Where the frequency of the red light is something around (4.3*10^14 Hz)
and the frequency of the infrared waves is in the range between (10^12 Hz and 10^14 Hz)
Then the correct option is b, infrared.
The force with which the student is acting in the chair and the force of the chair acting on the student is 588 N
Explanation:
- There are two kinds of forces acting on you when you are sitting on the chair, they are the gravitational force and the force exerted by the chair on you.
- The forces acting on the chair when you are sitting are the gravitational force and the force exerted by you.
- As per Newton's third law of motion, for every action, there is an equal and opposite reaction.
- Hence, F = ma
that is, F = 60 * 9.8
=588 N
- So, 588 N force should be applied from both sides then only you can sit properly in the chair.
The frequency corresponding to the lower cut-off point is
The speed of sound at a temperature of
is approximately
Therefore we can use the relationship between speed of a wave, frequency and wavelength to calculate the corresponding wavelength:
So, the corresponding wavelength is 22.87 m.
The thin atmosphere of Mars is thought to be due to the planet's lack of a magnetic field, which has allowed the Solar wind to blow away much of the gas the planet once had. Venus, despite still having a thick atmosphere of CO2, surprisingly has a similar problem
