When heat energy is transferred from direct contact between a warm and a cold object , it is known as heat transfer by conduction.
In conduction, the heat transfer takes place within an object or between two objects in contact until the temperature becomes uniform. this kind of heat transfer continues until the temperature at two ends between which the heat transfer take place , becomes equal. Heat transfer takes place from point at high temperature to point at lower temperature.
I think the answer is periodic motion.
Assuming the turntable is circular, its circumference is
(2 π) x (its radius) .
That's the distance covered by a point on its rim during every complete revolution.
The distance covered by the same point during 45 revolutions is
(45) x (2 π) x (radius).
So we can write . . .
Speed of the point = (45 rev/min) · (2 · π · 8 cm / rev)
Speed = (720 π) cm/minute
Speed = 12π cm/second
Speed = 37.7 cm/sec
<em>Speed = 0.377 m/s </em>
4. Grass - Caterpillar - Hedgehog - Fox
5. Caterpillar, Rabbit, Mouse.
6. Cougar and Fox.
7. Bacteria
8. The bird, hedgehog, Fox and cougar would be effected since the Hedgehogs and birds would soon die out due to the loss of their food. Once they die out, the cougar and Fox would have no predators left to eat.
Answer:
that is when the temperature near the surface is generally at its highest under conditions of sunny skies
