Answer:
11.18 minutes
Explanation:
We shall apply Newton's law of cooling
Rate of cooling ∝ Temperature difference
(T₂ - T₁ ) / t = k ( T₁ + T₂ / 2 - T )
A body cools from temperature of T₂ TO T₁ in time t , K being a constant.
(T₁ + T₂) /2 is the average temperature and T is temperature of surrounding.
Using the data given in the problem ,
For cooling from 425 degree to 300 degree
For cooling from 425 to 135 in time t we have
[/tex]
= 209k
From these two equations we get the value of t as
t = 16.18 s
So time required to cool from 300 to 135 degree isas follows
16.18 - 5 = 11.18 s
Answer:
Pupil
Explanation:
Part of the eye which controls the entering of light is called Pupil
The correct answer for the question that is being presented above is this one: "c. elastic." Most earthquakes are produced by the rapid release of
<span>elastic energy stored in rocks s</span>ubjected to great forces. The greater the elasticity of the energy, the more it is subjected to great forces.
<h2>
Weight of body in planet is 1798.17 N</h2>
Explanation:
Weight = Mass x Acceleration due to gravity
In Earth
784 = Mass x 9.81
Mass = 79.92 kg
Mass of body = 79.92 kg
Mass is a constant, it will not change planet to planet.
In planet
Weight = Mass x Acceleration due to gravity
Weight = 79.92 x 22.5
Weight = 1798.17 N
Weight of body in planet is 1798.17 N
New discoveries influence contemporary psychological perspectives because they provide new ways to look at things, or give new technology for new ways to diagnose problems and try to solve them.
