Question 2 (20 points)
zalisa [80]

Answer:

Energy

Explanation:

In the perspective of common people , almost all changes that we make need some sort of energy in order for it to happen. Even the simple ones.

(For example, When you want to turn on the lamp, you need to spend energy to push your finger down and press the switch.  When you wants to change your bed covers, you need to spend energy to walk down to the cabinet , take out the bed covers, and spend another energy during the removal and set up of the bed cover.)

Energy can be expressed using or Newton* meter as units, mean that you do a certain amount of work(Newton) over a distance (meter) and The ability to conserve or energy like food will be expressed as Joule(J).

Rockets are launched into space using jet propulsion where exhaust accelerates
Alona [7]

Answer:

Newton's Third Law of Motion

Explanation:

According to the given condition, the rocket is launched into space and it exhausts gases in the opposite direction of its movement. This condition is an example of Newton's Third Law of Motion. According to that, an action has a reaction but in an opposite direction. More precisely, if an object exerts a force on the other object, the second object will also exert an equal forceback on the first object. This condition satisfies what is mentioned in the statement and thus, it is an example of Newton's Third Law of Motion. Mathematically, it can be written as

F_{12} = -F_{21}

I have attached a figure for better understanding.

If a long-day plant has a critical night length of 9 hours, which 24 -hour cycle would prevent flowering?
julsineya [31]

If a long-day plant has a critical night length of 9 hours, a 24 -hour cycle of 14 hours light / 10 hours dark would prevent flowering.

Flowering plants are plants that bear flowers and fruits and form clade angiosperms, commonly called angiosperms.

The term “angiosperm” is derived from the Greek angeion (“vessel”) and sperma (“seed”) and refers to plants that produce seeds that are encased in fruit.

By far the most diverse group of land plants, with 64 orders, 416 families, about 13,000 known genera, and 300,000 known species. In earlier days, angiosperms were also called Magnoliophyta.

Many flowers have bright colors, strong scents and sweet nectar to attract pollinators. It can attract insects, birds, mammals and even reptiles.

When visiting flowers, pollinators pick up pollen from the anthers. When pollinators visit the next flower, some of the pollen sheds the stigma. This allows for cross-pollination and increases genetic diversity.
