Explanation:

The imaginary line passing through the center of the lens is called the principal axis of the lens.

If the incoming light rays comes parallel to the principal axis of a convex lens, then after refraction it will pass through the principal focus on the other side of the lens. All the rays meet at the focal point.

The rays of light converge after refraction converge at a point and that point is called as the principal force of the lens.

which view of the macroeconomy suggests that the speed of adjustment Purcell correction would be very quick
horsena [70]

Rational expectations theory suggests that the speed of adjustment Purcell correction would be very quick.

<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.

A 60-watt light bulb has a voltage of 120 bolts applied across it and a current of 0.5 amperes flows through the bulb. What is t
Andre45 [30]

Answer:

240 ohms

Explanation:

From Ohms law we deduce that V=IR and making R the subject of the formula then R=V/I where R is resistance, I is current and V is coltage across. Substituting 120 V for V and 0.5 A for A then

R=120/0.5=240 Ohms

Alternatively, resistance is equal to voltage squared divided by watts hence \frac {120^{2}}{60}=240

A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The block weighs 1587 g. From this information, calculate the d
mamaluj [8]

Answer:

11.3 g/cm^3

Explanation:

density = mass/volume

volume of rectangular prism = length * width * height

volume = (4.50 cm)(5.20 cm)(6.00 cm) = 140.4 cm^3

mass = 1587 g

density = (1587 g)/(140.4 cm^3)

density = 11.3 g/cm^3
