Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the

nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.

First, I chose to put a Chipotle container into the trash, instead of the recycling. This wasn’t the best decision, because it could have gone to the recycling and helped others.

Secondly, my family owns a compost bin and compost machine that helps compost vegetable waste, fruit scraps, coffee grounds, and other compostable items. Choosing to do this helps the environment in many ways.

Thirdly, I picked up many aluminum cans on the side of the road to crush and collect. After several months of collecting them in a container, my family and I bring them to a place that recycles and reuses metals and aluminum.

A performer, seated on a trapeze, is swinging back and forth with a period of 8.90 s. If she stands up, thus raising the center
iren2701 [21]

Answer:

8.800s

Explanation:

When the performer swings, she oscillates in SHM about Lo of the string with time period To = 8.90s.

First, determine the original length Lo, where for a SHM the time period is related to length and the gravitational acceleration by the equation

T = 2π×√(Lo/g)..... (1)

Let's make Lo the subject of the formulae

Lo = gTo^2/4π^2 ..... (2)

Let's put our values into equation (2) to get Lo

Lo = gTo^2/4π^2

= (9.8m/s^2)(8.90s)^2

------------------------------

4π^2

= 19.663m

Second instant, when she rise by 44.0cm, so the length Lo will be reduced by 44.0cm and the final length will be

L = Lo - (0.44m)

= 19.663m - 0.44m

= 19.223m

Now let use the value of L into equation (1) to get the period T after raising

T = 2π×√(L/g)

= 2π×√(19.223m/9.8m/s^2)

= 8.800s

If a swimmer cuts his foot on a seashell while wading in the ocean and bleeds into the seawater, his erythrocytes will shrink. W
Tom [10]

Answer:A) The ocean is hypertonic to the erythrocytes.

Explanation:cells shrink when placed in an hypertonic solution.

This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.

The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.

In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
