Which method involves using tools to control invasive species?

Physics
1 answer:
vitfil [10]3 years ago
5 0

Answer;

Mechanical control

Explanation;

-Invasive species may cause environmental harm, economic harm, or impact human health. A key factor that makes many species invasive is a lack of predators in the new environment.

-Mechanical control usually refers to the mowing or mechanical cutting of an invasive plant infestation to limit seed production. With mowing, timing is essential. Invasive plants must be removed before the plants go to seed in order to be an effective method of control. Plants should be cut as close to the ground as possible and may have to be treated more than once in a growing season to achieve desired results.

For each of the following velocity vectors, give the vector component, the scalar component, and the magnitude. (a) v = 48.0j m/
Oduvanchick [21]

Obtaining the component part of the letter 'i' warns that it is the velocity is oriented on the X axis. At the same time the numeric part, in this particular case will represent the scalar part and therefore the magnitude of the vector.

The velocity is

\vec{v} = 48.0\hat{i} \text{ m/s }

The vector component of the velocity is

v_x = 48.0m/s

The scalar component of the velocity is

v = 48.0m/s

The magnitude of the velocity is

v = 48.0m/s

you place a 0.13kg can of soup and a 0.34kg jar of pickles on the kitchen counter separated by a distance of 0.42m. what is the
Nonamiya [84]

Answer:

1.67×10^-11 N

Explanation:

m1 = 0.13kg

m2 = 0.34kg

d = 0.42m

G = 6.674 × 10 ^−11

F = Gm1m2/r²

F= (6.674 × 10^ −11×0.13×0.34)/(0.42)²

F = 1.67×10^-11 N

Kristine said that an ice cube gains heat when placed in a warm glass of water. Eric said that a hot cup of tea loses heat to co
Sindrei [870]

Answer:

Kristine is correct

Explanation:

this is because when an ice cube is placed into the warm water, it absorbs the heat from the water in order to melt which lowers the water's temperature.

in Eric's case, a hot cup of tea does not lose its heat because of cold hands. it varies depending on the cup whether it is a good insulator or not. also the heat can be lost through the air as well.

What is the difference in electrical potential energy between two places in an electric field?
Phoenix [80]

Answer: Option (c) is the correct answer.

Explanation:

The difference in electrical potential energy between two places in an electric field is known as potential difference.

Mathematically, potential difference between two given points can be written as follows.

             \Delta V = V_{2} - V_{1}

where,    \Delta V = potential difference

              V_{1} = potential at point 1

               V_{1} = potential at point 2
