Classify each of the following as descriptive of an object's speed or velocity.
When an object travels once around a circle at a constant rate of 20 m/s, the
Choose
is zero.
When an object travels once around a circle at a constant rate of 20 m/s, the
Choose
is 20 m/s.
When an object travels 8 meters north in 4 seconds and then 4 meters south in 2 seconds, the
Choose
is 2 m/s.
When an object travels 8 meters north in 4 seconds and then 4 meters south in 2 seconds, the
Choose
is 0.67 m/s.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

volts times amps 6 x 0.5 3w

more than, less

less than, more

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
