Assume a freely falling object were somehow equipped with a speedometer on a planet where the acceleration due to gravity is 20 meters per square second. By how much would its speed reading in- crease each second?

a. 10 m/s
b. 40 m/s
c. A value dependent on its initial speed 4. 30 m/s
d. 5 m/s
e. 20 m/s

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.

close lines strong magnet less close weaker

iron would move it is magnetic there is a mag field around the current in the wire

no simpler subs form complex ones. synthesise = make
