Farmers want to release a non-native insect in the fields that feeds on weeds. Before they do this, they consult a team of scien

tists and ask them to conduct a study that will determine the insects' effects on the farm land. Which statement best describes why farmers need the information from this study?
A. Farmers do not know much about insects; they would need to consult a team of scientists to answer questions such as where to get the insects, how to release them, and how to maintain control of the insect population after release.

B. It is important to do this study so that farmers will understand all the positive and possible negative results of releasing this new insect into the area so that they can make a decision on whether or not the benefits are worth the risks.

C. It is illegal to release new insects into an area. The farmers understand that if the study is conducted and the insects cause unexpected problems, the scientists would be held responsible for any resulting fines or fees.

D. The scientists will be able to tell the farmers if the insects will eat the weeds. Before the farmers spend the money on this project, they want to be assured the results will meet their expectations.

Answer: A. Farmers do not know much about insects; they would need to consult a team of scientists to answer questions such as where to get the insects, how to release them, and how to maintain control of the insect population after release.  

A non-native insect species will be the one which is introduced from different location either through immigration or by human introduction. In the given situation, as the farmers are planning to introduce non-native insects to remove the weeds, the farmers are not agricultural scientists or ecologists who could study the consequences of the introduction of the non-native insect species on the weed or other crops. The insects may either remove the weeds or may not cause any harm to the weeds. These insects may also kill the important crop producing plants.

Therefore, Farmers do not know much about insects; they would need to consult a team of scientists to answer questions such as where to get the insects, how to release them, and how to maintain control of the insect population after release is the correct reason why farmers need the information from this study.

Ede4ka [16]

Answer:

OT

It is important to wear protective equipments during games and practices.

Explanation:

Practice is a review of what is about to happen in some time to come and with practice ,the future can be trusted.

During practice it is very important to use protective gears or equipments because without them, injuries and accidents are liable to occur.

During the major game it is also important to prevent accidents or big injuries as the equipments protect each vital part of the body.

The velocity of the cannonball is 150 m/s,  the right option is B. 150 m/s.

The question can be solved, using Newton's second law of motion.

Note: Momentum of the cannon = momentum of the cannonball.

<h3>Formula:</h3>
  • MV = mv................. Equation 1

<h3>Where:</h3>
  • M = mass of the cannon
  • m = mass of the cannonball
  • V = velocity of the cannon
  • v = velocity of the cannonball

Make v the subject of the equation.

  • v = MV/m................ Equation 2

From the question,

<h3>Given: </h3>
  • M = 500 kg
  • V = 3 m/s
  • m = 10 kg.

Substitute these values into equation 2.

  • v = (500×3)/10
  • v = 150 m/s.

 

Hence, The velocity of the cannonball is 150 m/s,  the right option is B. 150 m/s.

Three kids are riding on a snow sled traveling horizontally without friction at 19.8 m/s. The masses of Kid A, B, and C are 42.8
Kamila [148]

Answer:

34.6 m/s

Explanation:

From conservation of momentum, the sum of initial and final momentum are equal. Momentum is a product of mass and velocity. Initial mass will be 42.8+31.5+25.9=100.2 kg

Final mass will be 31.5+25.9=57.4 kg

From formula of momentum

M1v1=m2v2

Making v2 the subject of the formula then

V2=\frac {M1v1}{m2}

Substitute 100.2 kg for M1, 19.8 m/s fkr v1 and 57.4 kg for m2 then

V2=\frac {100.2 kg\times 19.8 m/s}{57.4 kg}=34.56376 m/s\approx 34.6 m/s
