As per Newton's law of cooling we know that
in 5 hours the body temperature becomes 79.6 from 84.4
while the surrounding temperature is given as 68 degree F
now from above formula
now let say the person died "t" time ago
now we will have
so he died at approx 5 Am in morning
Answer:
0.168°C
Explanation:
The frictional force between the palms enables rubbing and initiates the heat deposed.
The energy generated per rub is;
The force × distance
Hence we have; 71.3 N×0.0750m
Hence for 11 rubs we have; 11× 71.3 N×0.0750m= 58.82J
Now this heat acquired by the tissue is the same as mass of tissue × specific heat capacity of tissue × temperature rise;
Expressed mathematically as;
58.82=0.100 kg×3500 J/(kg · °C)×∆T
∆T= 58.82/ 0.100 ×3500 =0.168°C
<em>Iron, and to a lesser degree, steel, can only become magnetised by passing an electrical current through it (an electromagnet). So a steel ship does not become magnetised in the accepted sense during construction. </em>
<span><em>However, any large mass of iron will affect the accuracy of a magnetic compass, causing it to deviate wildly from magnetic North. This problem was encountered when iron ships were first constructed in the mid-19 Century. It was overcome by mounting the compass in a 'binnacle', a housing containing two large soft iron balls either side of the compass itself, which counteracted the effect of the hull and balanced the compass so that it read correctly</em></span>
There are three things needed to be classified as a planet.
Pluto meets 2 of the 3.
The one it does not meet is it doesn’t “clear the neighborhood” which means a planet needs to be gravitationally dominant over all objects around it. Meaning smaller bodies ( asteroids) would either combine with the larger body making it bigger or pushing them away ( out of their orbit) so they do not collide with the larger body.
