Potential gravitational energy is computed with the formula:
Where:
PEgrav = Potential gravitation energy (J)
m = mass (kg)
h = height (m)
g = acceleration due to gravity (9.8m/s^2)
Take note that acceleration due to gravity is a constant.
All you need to do is put in what you know and solve for what you don't know. So your given is the following:
PEgrav = 3,528J
m = 24 kg
g = 9.8 m/s^2
Put that into your formula:
The height of the cliff is 15m.
Answer:
This is the remaining incomplete part of the question.
Requires separation of template strand Uses helicase Occurs during interphase of cell cycle Require primers Occurs in nucleus Requires dNTPs Produces Okazaki fragments Requires DNA polymerase Requires Primase Requires Taq DNA polymerase Requires cycles of heating Occurs in cytoplasm Occurs during anaphase of mitosis
Explanation:

Requires separation of template Requires separation of template
strand strand
Requires dNTPs Requires dNTPs
Uses helicase Requires cycles of heating
Requires Primase Require primers
Requires DNA polymerase Requires Taq DNA polymerase
Occurs during interphase of cell cycle
Occurs in nucleus Occurs in test tube
Produces Okazaki fragments
Egeria densa is an aquatic plant which has developed different means of carrying out photosynthesis under conditions of low carbon dioxide. During the process, the plant generate low pH at the leaf surface during high light intensity and this acidification shift the process equilibrium towards carbon dioxide which will then diffuse into the cell through passive diffusion.
Thus, if the student place the plant inside her fresh water tank, the plant will increase the carbon dioxide content of the water, which will lead to an increase in pH and the increase in pH will negatively affect the fish.
Answer:
Convergent.
Explanation:
The collision between two lithosphere plates on the surface of earth results in the formation of convergent plate boundaries. The process of subduction occurs when one plate converges over the other plate.
The diagram given in the question shows the convergent plate boundary. The collision of two lithospheric plates have been represented in the picture.
Thus, the correct answer is option (A).
Answer: A. 1
Mangrove swamps are wetland ecosystem found in the coastal area. These are found in regions where water body and terrestrial land meets. These ecosystem are dominated by mangrove trees due to their ability to servive in harsh saline water conditions. The roots of mangrove trees exhibit salt filteration system. These trees are habitat of many bird and animal species. The roots of these trees provide shelter, to underwater aquatic plant and animal species such as algea, prawns, sponges and fishes. Mangroves trees and algea are primary producers of the food chain in mangrove ecosytem. Mangrove tree leaves are eaten up by herbivores insects and algal species are consumed by large number of sea animals. Hence, mangrove tree and algea will be on the 1 number of the food chain.
