The particle’s velocity function will have the form v(t) = ntdi + otej + ptgk. enter an expression for d in terms of x, y, z, a, b, and c. 25% part (c) here is a set of parameter values for the motion of the particle: m = 1.8 kg, x = 1.5 m/s3, y = 2.8 m/s4, z = 0.15 m/s3, a = 3, b = 4, c = 3. calculate the x-component of the particle’s angular momentum, in units of kg˙m2/s, about the origin at time t = 1 s. 25% part (d) use the same set of parameter values (m = 1.8 kg, x = 1.5 m/s3, y = 2.8 m/s4, z = 0.15 m/s3, a = 3, b = 4, c = 3) to calculate the y-component of the particle’s angular momentum, in units of kg˙m2/s, about the origin at time t = 1 s.

The energy of a photon was found to be 3.38 × 10–19 j. planck’s constant is 6.63 × 10–34 j • s. which color of light corresponds to this photon?

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0

Which statement best describes the direction of the buoyant force on any object? a. opposite the force of gravity b. in the same direction as the weight c. in the direction of motion of the object d. opposite the direction of motion of the object
