The mass of the hoop is the only force which is computed by:F net = 2.8kg*9.81m/s^2 = 27.468 N
the slow masses that must be quicker are the pulley, ring, and the rolling sphere.
The mass correspondent of M the pulley is computed by torque τ = F*R = I*α = I*a/R F = M*a = I*a/R^2 --> M = I/R^2 = 21/2*m*R^2/R^2 = 1/2*m
The mass equal of the rolling sphere is computed by: the sphere revolves around the contact point with the table. So using the proposition of parallel axes, the moment of inertia of the sphere is I = 2/5*mR^2 for spin about the midpoint of mass + mR^2 for the distance of the axis of rotation from the center of mass of the sphere. I = 7/5*mR^2 M = 7/5*m
the acceleration is then a = F/m = 27.468/(2.8 + 1/2*2 + 7/5*4) = 27.468/9.4 = 2.922 m/s^2
Answer:
2.72 km
Explanation:
(12.33 km)/ 1 hr * (1 hr)/ 60 min
0.2055 km/ min
distance=rate * time (assuming v is constant,
a=0)
(0.2055 km/ min)*(13.22 min)
2.72 km OR 2716.71 m
Answer:
Explanation:
As we know that Far sighted person has near point shifted to 80 cm distance
so he is able to see the object 80 cm
now the distance of lens from eye is 2 cm
and the person want to see the objects at distance 10 cm
so here the image distance from lens is 80 cm and the object distance from lens is 8 cm
now from lens formula we have
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
