An ordinary workshop grindstone has a radius of 6.50 cm and rotates at 5500 rpm. (a) calculate the magnitude of the centripetal acceleration at its edge in m/s2 and convert it to multiples of g. g (b) what is the linear speed of a point on its edge? m/s

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
