Chapter 16, Problem 1Q

To determine

The meaning of the luminosity of the Sun.

Expert Solution & Answer

Explanation of Solution

Introduction:

The Sun is the largest and the only star in our solar system. It is composed of gases majorly Hydrogen and Helium. The radius of the sun is 695500 km and its surface temperature is 5800 K. The luminosity of the Sun is 3.828×1026 W.

The total energy released per unit time by the Sun is known as luminosity of the Sun. The SI unit of luminosity is Watts or Joules per second. The luminosity of the Sun is 3.828×1026 W which is also written as 1L⊙ (1 solar luminosity). The luminosity of other stars and galaxies is referred in terms of solar luminosity. For example, the luminosity of the brightest star in our sky, Sirius is 25.4L⊙. This means, Sirius radiates 25.4 times the totalenergy emitted per unit time. Luminosity depends on the size and temperature of the object.

The rectangular loop of wire shown in the figure (Figure 1) has a mass of 0.18 g per centimeter of length and is pivoted about side ab on a frictionless axis. The current in the wire is 8.5 A in the direction shown. Find the magnitude of the magnetic field parallel to the y-axis that will cause the loop to swing up until its plane makes an angle of 30.0 ∘ with the yz-plane. The answer is .028 T, I just need help understanding how to do it. Please show all steps.

A ray of light from an object you want to look at strikes a mirror so that the light ray makes a 32 degree angle relative to the normal line (a line perpendicular to the surface of the mirror at the point where the ray strikes the mirror). If you want to see the object in the mirror, what angle does your line of sight need to make relative to the normal line? Give your answer as the number of degrees.

Suppose you have a converging lens with a focal length of 65 cm. You hold this lens 120 cm away from a candle. How far behind the lens should you place a notecard if you want to form a clear image of the candle, on the card? Give your answer as the number of centimeters.
