Consider a sphere of radius a that is charged over its volume with a charge density p= and is situated in free space. the electric field intensity vector at a point whose radial distance from the sphere center is r is the same as e due to a point charge placed at the sphere center for the following range of values of r only: a-a

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
