Solar scientists want to measure the temperature inside the sun by sending in probes. Imagine that temperature increases by 1 million◦C for every 10,000 km below the surface. A probe that can handle a temperature of x million degrees costs x³ million dollars. a. How much would it cost to measure the temperature 10,000 km down? b. How much would it cost to measure the temperature 100,000 km down? c. How much would it cost to measure the temperature 200,000 km down?

converted to energy. How many joules (J) of energy are produced?
1. Read and Understand
What information are you given?
Mass= m = 0.15 kg
Speed of light = c = 300,000,000 m/s=3x108 m/s
2. Plan and Solve
What unknown are you trying to calculate?
The amount of energy produced = E = ?
What formula contains the given quantities and the unknown?
E = mc²
Replace each variable with its known variable and known value.
E = (0.15 kg)(3.00 × 108 m/s)²
E = 1.35 x 10¹6 kg.m²/s2 = 1.4 x 10¹6 J
3. Look Back and Check
Is your answer reasonable?
Yes, the calculated number is quite large compared to the mass, and the units
indicate energy.

4. If the intensity of the Sun peaks in the optical range, at a frequency of about 3:4 x 10 Hz, what is the
temperature of the Sun? Use the Wien displacement law (1.25). If all of the power is emitted only between
3 and 4 x 10 Hz, how many photons per cm² arrive at the earth when the Sun is directly overhead? What
is the power received on earth per cm³? A value for the solar power is 135mW per cm². How does this
compare to your calculation?
