Smooth ice reduces the unbalanced forces that would slow the hockey puck.
If there is no slipping or skidding going on, then for each revolution, the tire rolls along the ground a distance equal to the tire's circumference.
Circumference of the tire = 2 · π · Radius .
During the same revolution, the small stone stuck in the tread travels in a big semicircular arc that's <em>(2 · π · r)</em> long. (roughly 6.28r)
Because the core is the hottest place at which it holds the most heat to bring it out to be towards africa.

Answer:
5.01×10⁴ J.
Explanation:
Applying,
q = Cm....................... Equation 1
Where q = amount of heat needed to melt the ice, m = mass of the ice, C = specific latent heat of ice.
From the question,
Given: m = 150 g = (150/1000) kg = 0.15 kg, C = 3.34×10⁵ J/kg
Substitute these values into equation 1
q = (0.15×3.34×10⁵)
q = 0.501×10⁵ J
q = 5.01×10⁴ J.
