Answer:
Mintu should have chosen a material with a lower specific heat.
Explanation:
When we talk about specific heat, we refer to a specific quantity of heat that is needed for a substance or material to rise its temperature. In more concrete terms, is the amount of heat required for 1 gram of substance/material to elevate its temperature by 1 degree Celsius.
This would mean that a material with a high specific heat would require a higher quantity of heat to increase its temperature, so in this case, if Mintu wanted to make the heat transfer easier between the metal iron and the other piece of metal, he should have chosen a material that could elevate its temperature by receiving a lower quantity of heat, that is a material with a low specific heat. But instead he chose a metal with a higher specific heat, which will now make the heat transfer more difficult,and that was the error.
Answer:
![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
Explanation:
The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.
A number can be written as
in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
So, the distance in scientific notation is : ![D=5.89\times 10^{12}\ km](https://tex.z-dn.net/?f=D%3D5.89%5Ctimes%2010%5E%7B12%7D%5C%20km)
<span>The answer is B. We require trees to breath. We would be stuck in an unfortunate situation without our woods. Trees expel carbon dioxide from the environment and discharge oxygen through a procedure called photosynthesis. Basically all creature life on Earth needs oxygen to inhale and woodlands assume a key part in the complex worldwide oxygen cycle.</span>
An important tool of genetic engineering is recombinant DNA, which is DNA altered by the incorporation of genes from a different organism.
The modification and manipulation of an organism's genes through technology are known as genetic engineering, often referred to as genetic modification or genetic manipulation. It is a collection of technologies used to alter cells' genetic make-up, including the movement of genes between and within species to create better or entirely new organisms.
Recombinant DNA techniques are used to isolate and copy the genetic material of interest, while artificial DNA synthesis is used to create new DNA. Paul Berg combined DNA from the lambda virus and the SV40 monkey virus in 1972 to create the first recombinant DNA molecule.
