Answer: Both
Explanation:
KE can be solve using the formula:
ke = 0.5 mv^2
where m is the mass of the object
v is the velocity
ke = 0.5 ( 2 kg ) ( 5 m/s)^2
ke = 25 J
the GPE can be solved using the formula:
GPE = mgh
where m is the mass
g is the acceleration due to gravity ( 9.81 m/s^2)
h is the height
GPE = ( 4 kg)(9.81 m/s^2)( 40 m)
GPE = 392.4 J

Where, in terms of an ellipse, is the Sun located with respect to the orbit of each planet? Which
one of Kepler's Laws does your answer support?
Answer:
focus
The Sun is at one focus. The planet follows the ellipse in its orbit, meaning that the planet to Sun distance is constantly changing as the planet goes around its orbit. Kepler's Second Law: the imaginary line joining a planet and the Sun sweeps equal areas of space during equal time intervals as the planet orbits.

What are Chromatids in biology
Answer:
A chromatid is one of two identical halves of a replicated chromosome. During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes.
Explanation:
A scientist fills a glass container with water and places an aquatic plant inside the container, then closes the lid and places the
container in direct sunlight. The scientist observes small bubbles on the surfaces of the plant's leaves on days 1 and 2, but no
bubbles on day 3. The scientist concludes that the bubbles were caused by photosynthesis. Which substance should be
added to the water in order for the bubbles to reappear? (1 point)
Answer: Are there any options? you either add C02 because it has run out gas or you and in minerals that also contain C02.
Explanation: you need C02 to have photosynthesis, so with a closed off lid, the gas is going to eventually run out.
Carbon dioxide should be added to the water in the container in order for the bubbles to reappear in the glass container while placed in sunlight. Carbon dioxide is a component of photosynthesis.
What is Photosynthesis?Photosynthesis is the process by which plants prepare their own food in sunlight and in the presence of carbon dioxide gas. Photosynthesis process takes place in the chloroplast of cells.
Photosynthesis is an anabolic reaction in which carbon dioxide and water reacts in the presence of sunlight which is trapped by the chlorophyll present in the leaves of plant to produce glucose (carbohydrate) and oxygen gas, which is later utilized in the process of respiration.

b. Which types of reproduction are followed in sugar cane plant and in mango tree?
Sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.
Sugar cane is usually reproduce by using asexual reproduction i.e. by the use of pieces of stem of sugar cane called setts that contain at least one node. It is necessary that these cuttings contain a node because when they are placed and covered in the ground, primary roots arise from these nodes.
While on the other hand, the mango trees can be propagated both by sexual and asexual reproduction. Sexual reproduction involves the fusion of male and female sex cells during flowering stage. Grafting, Cutting, Layering and Budding are the asexual means for the propagation of mango tree.
Among these the grafting technique is considered as the most suitable method of vegetative propagation of mango so we can conclude that sugar cane plant reproduce asexually whereas mango can reproduce by both asexually and sexually.

What effect does increase salinity have on the density of water?
1. No affect unless temperature also changes
2. Decreases density
3. Increases density
Answer:
3
Explanation:
For example,The density of seawater depends on the content of salt. It is known that the density of salt is 2.165g/cm3, so the more salt, the greater the density of mixed liquid.
Answer:If you know that dissolution of salt only marginally affects the volume of the solution, how would you expect the density to evolve? It should reasonably increase.
Explanation:
at a given temperature, Should salts be dissolved in the water, and the volume remains reasonably constant, the density
. A solute binds water molecules around itself in a coordination sphere, and should a salt be dissolved, both anion and cation must be solvated; hence an increase in solution density with respect to water.
