Answer:
Explanation:
1 advantage of genetic engineering:
It allows for a faster growth rate. Because with genetic engineering, plants and animals are allowed to be modified so their maturity would occur at a quicker pace.
1 disadvantag of genetic engineering:
The nutrition value of foods can be less. For example, in a research show that genetic enginnering make chicken increase the fat content by 220% but reduced the amount of protein.
1 advantage of cloning:
When cloning, the object would be able to create tissue and organs that doctor can use when needed during the surgery.
1 disadvantage of cloning:
If original organism has genetic deffects, it will be passed down through all the continuous generations
1 advantage of artificial selection (can be called as selective breeding):
It will provide improvements to plants and animals. For example, seedless fruits, increast the tast of food, etc.
1 disadvantage of artificial selection (can be called as selective breeding):
It may lead to a lack of variety in plant or animal species. As the breeding is selective so the variety in plant would be decrease. For example, people like seedless fruits than normal included-seed fruit so that would make the new fruit become more popular and may lead to decrease the diversity in fruits.
Hope this help you :3
AWWWWW TAKE SO LONG TO RESEARCH AND WRITE :D:D
This measure of the total amount of matter an object contains is called mass. The unit used for mass is the kilogram or kg for short.
I hope this helps!
Answer:
L = 16 [in]
Explanation:
In order to find the arch we must first find the angle that forms the circular sector, using the following formula:
![A = \frac{\alpha*r^{2} }{2} \\where:\\A= area = 64[in^{2}]\\r = radius = 8[in]\\\\\alpha = angle[rad]therefore\\\alpha =\frac{2*A}{r^{2} } \\\alpha =\frac{2*64}{8^{2} } \\\alpha =2[rad]](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%5Calpha%2Ar%5E%7B2%7D%20%7D%7B2%7D%20%5C%5Cwhere%3A%5C%5CA%3D%20area%20%3D%2064%5Bin%5E%7B2%7D%5D%5C%5Cr%20%3D%20radius%20%3D%208%5Bin%5D%5C%5C%5C%5C%5Calpha%20%3D%20angle%5Brad%5Dtherefore%5C%5C%5Calpha%20%3D%5Cfrac%7B2%2AA%7D%7Br%5E%7B2%7D%20%7D%20%5C%5C%5Calpha%20%3D%5Cfrac%7B2%2A64%7D%7B8%5E%7B2%7D%20%7D%20%5C%5C%5Calpha%20%3D2%5Brad%5D)
Now using the following equation we can calculate the arc length
![L=\alpha *r\\L=2*8\\L=16[in]](https://tex.z-dn.net/?f=L%3D%5Calpha%20%2Ar%5C%5CL%3D2%2A8%5C%5CL%3D16%5Bin%5D)
Answer:
The experiment to determine the coefficient of static friction between a rough block and an incline plane is detailed in the explanation.
Explanation:
A simple experiment is as follows:
Take a weight in which its mass is known and hold it with a roller at the end of the inclined plane with a rope.
Place the weight on the plane inclined horizontally with the ground, forming a zero degree angle.
Gradually lift the weight so that the angle of incline begins to increase.
Observe that the weight will begin to slide. This angle will be the angle theta.
In this way, the coefficient of friction will be calculated as the tangent of the angle theta.
Take a different weight and repeat the procedure to get different values of the coefficient of friction.
By averaging the coefficients of friction, a final value will be obtained.
