Answer:

• Angular velocity is 2 m/s

• Centripetal force is 96 N

Explanation:

For angular velocity:

{ \rm{v =  \omega r}}

  • v is velocity
  • w is angular velocity
  • r is radius

{ \rm{ \omega =  \frac{v}{r} }} \\  \\ { \rm{ \omega =  \frac{12}{6} }} \\  \\  { \boxed{ \rm{ \omega = 2 \:  {ms}^{ - 1} }}}

For the centripetal force:

{ \rm{force = m { \omega}^{2}r }} \\  \\ { \rm{force = (4 \times  {2}^{2}  \times 6)}} \\  \\ { \rm{force = 96 \: newtons}}

Nezavi [6.7K]

Answer:

The liquid turns to a gas.

Explanation:

If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. Particles in the middle of the liquid form bubbles of gas in the liquid.
