A car with a mass of 1,324 kilograms, traveling at a speed of 20 meters/second, crashes into a wall and stops. What is the kinetic energy after this perfectly inelastic collision?
The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
How to calculate kinetic energy?The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
K.E = kinetic energym = mass v = velocityK.E = ½ × 1324 × 20²
K.E = 264800J
Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

A) even more of the cell than when it was in water
B) less of the cell than when it was in water
C) the same amount of the cell as when it was in water
Answer:
A=even more of the cell than when it was in water
Answer:
When a red onion cell is placed in a 5% NaCl solution, the central vacuole will occupy
B) less of the cell than when it was in water
This is due to plasmolysis
Explanation:
What is plasmolysis?Plasmolysis is the process in which there is a loss of water from cells when these are placed in a hypertonic solution. The protoplast and vacuole shrinks away from the cell wall.
What is a hypertonic solution?Hypertonic solution is that which has higher concentration of solutes (low water concentration) as compared to inside the cell. As water moves from high conc. to low conc., it moves from inside the cell to outside. Thus, the vacuole pulls away from the cell when placed in a hypertonic solution (5% NaCl).

Bees are commonly found near flowering plants.
(a) Describe how bees help plants to reproduce.
Answer:
bees like flowers because they have pollen in their wings, and it makes them happy, and that’s nice. They make beautiful little things that can be used to make honey.
Explanation:
The foundation of the best honey is flowers and pollen. When they’re all in bloom, it’s a wonder for bees to come to them—not because of their beautiful colours but rather for how much sweetness there is in them. The smell alone makes every person nearby fall in love with bees. The only downside? The flowers die within weeks when exposed to too much pollen. They can only take so many blooms before it becomes too toxic for humans to eat, even if they don’t have to go through the hassle of killing a human to obtain them.
But that doesn’t mean bees hate the sight of flowers.
It has been said that flowers are what make people happy. That they can make anyone smile despite the circumstances. And maybe if people saw more flowers they would be happier? But it doesn't always work like that.
The plants around her garden
Answer:
PollinationExplanation:
In its natural state, the flower is inverted with the standard petal at the bottom. when a heavy insect such as BEE visits the flower, it lands on the standard petal.The Insects follow the nectar guide into the flower.The insect forces its way in between the two wing petals and moves in to collect the nectar.The insect's back forces the keel petal upwards to expose the stigma and anthers. The stigma and anthers brush against the hairy back of the insect. when this happens, some pollen grains from the anther stick to the hairy back of the insect. At the same time, pollen grains on the insect's back (from another flower which the insect had visited earlier) are transformed into a sticky stigma.when the insect leaves the flower, the keel springs back to its original position to enclose the stamen and the stigma again.Refer to Attachment
