Answer:
Explanation:
Given
Tom is on half way between the center and the outer rim
Mary is on the extreme outer rim
Suppose is the angular velocity of ride with radius of outer rim be R
angular acceleration of Ride
At any instant both Tom and Mary experience the same angular speed
(b)Linear velocity at any instant
Thus Tom has higher linear speed
(c) For radial Acceleration
Tom has higher radial Acceleration as it is directly Proportional of radius
Internal combustion engine
It's the first one. Believe me I always missed this question in class, never is ask a question first. Hypothesis is first.
Answer:
Melting occurs when a solid is heated and turns into a liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place.
During the melting point, the particles start to move about, staying close to their neighboring particles, then move more freely.
Explanation:
As a substance melts and goes from a solid to a liquid state, the kinetic energy of the molecules increases and moves faster, and separates further away from each other. This is why a liquid can fill the shape of its container, where a soild has a fixed shape.
