A boy, standing at point O, is whirling a ball on a string over his head. After several whirls, he lets go of the string and the
Vikki [24]
When a ball is whirled using a string, it is restricted to move only in circular motion because the net force acting on the ball is towards the center of the circle. Hence, the acceleration of the ball is towards the center. But the velocity of ball is tangential to this circular path all the time. When the whirling is stropped, the string becomes slack and tension in the string becomes zero. The ball no more performs circular motion and the ball moves tangentially to the circle in straight line. Therefore, before letting go, velocity was variable. After letting go, velocity becomes constant.

Your bike gets a flat tire. Its mass is 10 kg and you are able to accelerate your bike .5 m/s/s. What is the force on the bike..
STALIN [3.7K]

Answer:

50N

Explanation:

Given parameters:

Mass of the bike   = 10kg

Acceleration  = 5m/s²  

Unknown:

Force on the bike  = ?

Solution:

To solve this problem, we apply Newton's second law of motion.

  Force  = mass x acceleration

 Force  = 10 x 5 = 50N

What is the lowest temperature possible
dimulka [17.4K]

At the physically impossible-to-reach temperature of zero kelvin, or minus 459.67 degrees Fahrenheit (minus 273.15 degrees Celsius), atoms would stop moving. As such, nothing can be colder than absolute zero on the Kelvin scale.

Explanation:

A basic quantity is basically the physical quantity that can not be defined in terms of other quantities.

Some of the names of the basic quantities include:

  1. Mass, denoted by the symbol 'm', with S.I. unit 'kg'
  2. Length, denoted by symbol 'l', with S.I. unit 'm'
  3. Time, denoted by symbol 't', with S.I. unit 's'
  4. Current, denoted by 'I', with S.I. unit 's' 'A'
  5. Temperature, denoted by 'T', with S.I. unit 'K'
  6. Amount of substance, denoted by 'n', with S.I. unit 'mol'
  7. Luminous Intensity, denoted by 'Iv', with S.I. unit 'cd'

  • A basic quantity is chosen arbitrarily.
