(PLEASE HELP. DUE IN 4 HOURS. I WILL CASHAPP YOU $20 TO GIVE A CORRECT ANSWER. PLEASE LEGIT ANSWERS. I AM DESPERATE. GIVING BRAINLIEST, THANKS, AND 5 STARS. THANK YOU.) In Video 2, you observed a "Frictionless Pendulum", the frictionless pendulum can only be simulated. Go back and see if you can observe any changes in motion. How would the motion of the pendulum change if that was a demonstration rather than a simulation? Use the CER (claim, evidence, reasoning) template to answer.

CLAIM: Write your answer to the question given: The motion of a real pendulum would (describe how it would or would not change).

EVIDENCE: This is your example, model, observation, or idea demonstrating your claim, you could begin with “According to…” or “Based on...”, or "Watch how..."

REASONING: You could begin with, “This is because…” or “The fact that supports this evidence is…”. ONLY state science facts to support your example, do not guess, use opinion, or use inferences here.

Search coils and credit cards. one practical way to measure magnetic field strength uses a small, closely wound coil called a search coil. the coil is initially held with its plane perpendicular to a magnetic field. the coil is then either quickly rotated a quarter-turn about a diameter or quickly pulled out of the field. (a) derive the equation relating the total charge q that flows through a search coil to the magnetic-field magnitude b. the search coil has n turns, each with area a, and the flux through the coil is decreased from its initial maximum value to zero in a time ∆t. the resistance of the coil is r, and the total charge is q = i∆t, where i is the average current induced by the change in flux. (b) in a credit card reader, the magnetic strip on the back of a credit card is rapidly “swiped” past a coil within the reader. explain, using the same ideas that underlie the operation of a search coil, how the reader can decode the information stored in the pattern of magnetization on the strip. (c) is it necessary that the credit card be “swiped” through the reader at exactly the right speed? why or why not?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?
