1.4.2.4 Quiz: Electromagnetism Question 1 of 10
Felix connects a wire coil to an ammeter and moves a bar magnet around the
outside of the coil. He wants to show that a moving magnet can cause an
electric current in a wire. Which change should Felix make so that the
ammeter will detect a current?
O A. He must rotate the magnet as it moves around the wire coil.
B. He must move the magnet through the inside of the wire coil.
O C. He must move the magnet along the connecting wires.
O D. He must arrange the connecting wire in the correct direction.

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.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
