The tension in the upper rope is determined as 50.53 N.
<h3>Tension in the upper rope</h3>
The tension in the upper rope is calculated as follows;
T(u) = T(d)+ mg
where;
- T(u) is tension in upper rope
- T(d) is tension in lower rope
T(u) = 12.8 N + 3.85(9.8)
T(u) = 50.53 N
Thus, the tension in the upper rope is determined as 50.53 N.

Answer:
The temperature is ![T = 168.44 \ K](https://tex.z-dn.net/?f=T%20%20%3D%20168.44%20%5C%20K)
Explanation:
From the question ewe are told that
The rate of heat transferred is ![P = 13.1 \ W](https://tex.z-dn.net/?f=P%20%20%3D%2013.1%20%5C%20W)
The surface area is ![A = 1.55 \ m^2](https://tex.z-dn.net/?f=A%20%3D%201.55%20%5C%20m%5E2)
The emissivity of its surface is ![e = 0.287](https://tex.z-dn.net/?f=e%20%3D%200.287)
Generally, the rate of heat transfer is mathematically represented as
![H = A e \sigma T^{4}](https://tex.z-dn.net/?f=H%20%20%3D%20%20A%20e%20%5Csigma%20%20T%5E%7B4%7D)
=> ![T = \sqrt[4]{\frac{P}{e* \sigma } }](https://tex.z-dn.net/?f=T%20%20%3D%20%20%5Csqrt%5B4%5D%7B%5Cfrac%7BP%7D%7Be%2A%20%5Csigma%20%7D%20%7D)
where
is the Boltzmann constant with value ![\sigma = 5.67*10^{-8} \ W\cdot m^{-2} \cdot K^{-4}.](https://tex.z-dn.net/?f=%5Csigma%20%20%3D%205.67%2A10%5E%7B-8%7D%20%5C%20W%5Ccdot%20%20m%5E%7B-2%7D%20%5Ccdot%20%20K%5E%7B-4%7D.)
substituting value
![T = \sqrt[4]{\frac{13.1}{ 0.287* 5.67 *10^{-8} } }](https://tex.z-dn.net/?f=T%20%20%3D%20%20%5Csqrt%5B4%5D%7B%5Cfrac%7B13.1%7D%7B%200.287%2A%205.67%20%2A10%5E%7B-8%7D%20%7D%20%7D)
![T = 168.44 \ K](https://tex.z-dn.net/?f=T%20%20%3D%20168.44%20%5C%20K)
Meiosis creates the gamete cells, because these cells are used in reproduction they only have 26 chromosomes two of these cells join together to make a full 46 chromosomes.
Hope this helps! :)
Answer:
the branch of science concerned with the nature and properties of matter and energy
Answer:
Gametes are the cells used during sexual reproduction to produce a new individual organism.
Explanation:
The male gamete or sperm, is a smaller, mobile cell that meets up with the much larger and less mobile female gamete, egg or ova.
