Acar with a mass of 2,000 kilograms is moving around a circular curve at a uniform velocity of 25 meters per second. the curve has a radius of 80 meters what is the centripetal force on a car

When the velocity of an object is doubled, by what factor is its momentum changed? by what factor is its kinetic energy changed? a) the momentum is zero. b) the momentum is not zero. c) difficult to say.

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

15. give an example for some particles or waves that are moving faster than light in everyday life 16. what is a laser? 17. what is an oscilloscope? 18. what does it means practically that nothing is faster than light in vacuum? 19. what is vacuum?
