Answer:
Velocity of the electron = v = 1.2\times 10^8\ m/s.
Explanation:
Given,
- Mass of the electron =
- Charge on the electron =
- Charge density of the ring =
- Radius of the ring = R = 0.70 m
- Distance between the electron ant the center or the ring = x = 0.5 m
Now total charge on the ring = 
Potential energy due to the charged ring to the point on the x-axis is
Let v be the velocity of the electron at the center of the ring.
Total kinetic energy of the electron = 
Now, From the conservation of energy,
the total potential energy of the electron at initially is converted to the total kinetic energy of the electron at the center of the ring,
Hence the velocity of the electron on the center of the charged ring is 
Answer:
16.1 N
Explanation:
From the question,
F = ma.............................. Equation 1
Where F = horizontal force, m = mass of the object, a = acceleration .
Given: m = 7.0 kg, a = 2.3 m/s²
Substitute this values into equation 1
F = (7.0×2.3)
F = 16.1 N.
Hence the magnitude of the horizontal force is 16.1 N

<h3>What Is Rational Expectations Theory?</h3>
The rational expectations theory is a widely used concept and modeling technique in macroeconomics. Individuals make decisions based on three primary factors, according to the theory: their human rationality, the information available to them, and their past experiences.
The rational expectations hypothesis was originally suggested by John (Jack) Muth 1 (1961) to explain how the outcome of a given economic phenomena depends to a certain degree on what agents expect to happen.
- People who have rational expectations always learn from their mistakes.
- Forecasts are unbiased, and people make decisions based on all available information and economic theories.
- People understand how the economy works and how government policies affect macroeconomic variables like the price level, unemployment rate, and aggregate output.

Answer:
Low pressure systems typically arrive with storms and clouds. Air motion is usually upwards, as heated are is less dense and more buoyant than cooler air. A high pressure system is typically cooler than its counter-part, and skies are usually clear. Low pressure systems carry more water vapor due to rising hot air cooling and condensing.
