A hole is drilled from the surface of Earth to its center. Ignore Earth's rotation and air resistance, and model Earth as auniform sphere. For the following answers, use g for theacceleration due to gravity, R_E for RE, andm, as necessary.)(a) How much work is required to lift aparticle of mass m from the center of Earth to Earth'ssurface?W = 1(b) If the particle is dropped from rest at the surface of Earth, what is its speed when it reaches the center of Earth?v = 2(c) What is the escape speed for a particle projected from thecenter of Earth?vesc = 3

One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. you see that the patch of light seems to be a circular diffraction pattern. it appears that the central maximum is about 1 cm across and you estimate that the distance from the window shade to the wall is about 3 m. what is (a) the average wavelength of sunlight? (b) the diameter of the pinhole?
