QUESTION 1

A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of mc001-1. Jpg 6. 67

Andrei [34K]

The approximate length of the arc intersected by the central angle is 20.94 inches.

The given parameters:

Radius of the circle, r = 10 inches
Central angle, $\theta = \frac{2\pi }{3} \ rad$

The approximate length of the arc intersected by the central angle is calculated as follows;

S = rθ

where;

S is the length of the arc

Substitute the given parameters and solve for the length of the arc

$S = 10 \ in \times \frac{2\pi }{3} \\\\S = 20.94 \ inches$

Thus, the approximate length of the arc intersected by the central angle is 20.94 inches.

Crazy boy [7]

Answer:

a) 4458K b) 5048K, c) 6166K, d) 5573K

Explanation:

The temperature of the stars and many very hot objects can be estimated using the Wien displacement law

$\lambda_{max}$ T = 2,898 10⁻³ [m K]

T = 2,898 10⁻³ / $\lambda_{max}$

a) indicate that the wavelength is

Lam = 650 nm (1 m / 109 nm) = 650 10⁻⁹ m

Lam = 6.50 10⁻⁷ m

T = 2,898 10⁻³ / 6.50 10⁻⁷

T = 4,458 10³ K

T = 4458K

b) lam = 570 nm = 5.70 10⁻⁷ m

T = 2,898 10⁻³ / 5.70 10⁻⁷

T = 5084K

c) lam = 470 nm = 4.70 10⁻⁷ m

T = 2,898 10⁻³ / 4.7 10⁻⁷

T = 6166K

d) lam = 520 nm = 5.20 10⁻⁷ m

T = 2,898 10⁻³ / 5.20 10⁻⁷

T = 5573K
