The figure shows a pendulum of length l = 2.8 m. its bob (which effectively has all the mass) has speed v0 when the cord makes an angle θ0 = 45° with the vertical. (a) what is the speed of the bob when it is in its lowest position if v0 = 6.0 m/s? what is the least value that v0 can have if the pendulum is to swing down and then up (b) to a horizontal position, and (c) to a vertical position with the cord remaining straight? (d) do the answers to (b) and (c) increase, decrease, or remain the same if θ0 is increased by a few degrees?

Apoint charge +q is at the origin. a spherical gaussian surface centered at the origin encloses +q. so does a cubical surface centered at the origin and with edges parallel to the axes. select "true" or "false" for each statement below. the electric flux through the spherical surface is greater than that through the cubical surface. suppose (for this statement only), that q is moved from the origin but is still within both the surfaces. the flux through both surfaces remains unchanged. the area vector and the e-field vector point in the same direction for all points on the spherical surface. the e-field at all points on the spherical surface is equal due to spherical symmetry. the flux through the spherical gaussian surface is independent of its radius.
