Langerhans cells exist on the surface of the skin. They help to protect you by keeping dangerous microbes from entering your body. Langerhans cells do this in two very different ways: by protecting your skin from infection and also by stimulating allergic reactions.
It is a very reactive metal with 11 protons ,12 neutrons, 11 electrons, and 1 valence electron
To solve this problem it is necessary to apply the concepts related to the Stefan-Boltzman law that is responsible for calculating radioactive energy.
Mathematically this expression can be given as
Where
A = Surface area of the Object
Stefan-Boltzmann constant
e = Emissivity
T = Temperature (Kelvin)
Our values are given as
Replacing at our equation and solving to find the temperature 1 we have,
Therefore the the temperature of the coldest room in which this person could stand and not experience a drop in body temperature is 12°C
Answer:
10.032 N.
Explanation:
From the question given above, the following data were obtainedb
Mass (m) = 2.5 Kg
Final length = 10.0 cm
Original length = 21.4 cm
Spring constant (K) = 88 N/m
Force (N) =?
Next, we shall determine the compression of the spring. This can be obtained as follow:
Final length = 10.0 cm
Original length = 21.4 cm
Compression (e) =?
e = Original length – final length
e = 21.4 – 10
e = 11.4 cm
Next, we shall convert 11.4 cm to m. This can be obtained as follow:
100 cm = 1 m
Therefore,
11.4cm = 11.4 cm × 1 m / 100 cm
10 cm = 0.114 m
Finally, we shall determine the force. This can be obtained as illustrated below:
Compression (e) = 0.114 m
Spring constant (K) = 88 N/m
Force (N) =?
F = Ke
F = 88 × 0.114
F = 10.032 N
Thus, the force in the spring is 10.032 N
