A 0.100–kilogram white ball moving with a velocity of 5 meters/second along the positive x–axis hits a stationary blue ball of the same mass. Energy is not necessarily conserved, but momentum is. After the collision, the white ball moves off at an angle of 20° with respect to the positive x–axis and at a velocity 3.5 meters/second. The blue ball moves at an angle of –35° and a velocity of 2.1 meters/second. What is the final y–momentum of the system?

A-4.60 μc charge is moving at a constant speed of 6.80×105 m/s in the +x−direction relative to a reference frame. at the instant when the point charge is at the origin, what is the magnetic-field vector it produces at the following points.

Which example has gravitational potential energy? a.a horse slowing down from a run b.an apple about to fall from a tree branch c.a bicycle being pedaled down a horizontal path d.beaker sitting on the floor

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.
