Answer: Circadian Rhythms
There are three types of biological rhythms.
→The one that occurs about every day (approx 24 hours) is known as Circadian Rhythms. For example, Hormone secretion, urine production, sleep etc.
→The one that occurs after more than a day like menstrual cycles of women (28 days) is known as Infradian Rhythms.
→The one that occurs more than once a day is known as Ultradian Rhythms like sleep, hormone levels etc.
Therefore, a biological cycle that is approximately 25 hours long is called Circadian Rhythms.
The car covers a distance <em>d</em> after time <em>t</em> of
<em>d</em> = (2.8 m/s²) <em>t</em>²
Solve for <em>t</em> when <em>d</em> = 69 m:
69 m = (2.8 m/s²) <em>t</em>²
<em>t</em>² = (69 m) / (2.8 m/s²)
<em>t</em> ≈ 4.96 s
Answer:
the amount of heat that gets through both the wires will be same.
Explanation:
By the Fourier's law of conduction we have:
where:
= rate of heat transfer
k = thermal conductivity of the material
A = area of the material
dT = temperature difference across the length dx
According to the question, the system to be analysed is isolated from the surrounding.
Until the thermal equilibrium is established between aluminium and copper wires the amount of heat that gets through both the wires will be same.
<em>But the rate of heat transfer through the aluminium will be greater as it has double the thermal conductivity of copper.</em>
Answer:
We define a vector as an object with a length and a direction.With no length, the zero vector is not pointing in any particular direction, so it has an undefined direction.
