Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
Photosynthesis is the process plants undergo when they use carbon dioxide and sunlight to produce energy.
Hope this helped!!! :-)
have a nice day :-)
The hormones are sent as chemical signals
Answer:
Explanation:
The more similar the two species are, the more their niche overlaps and the more competition there is.
<em>The most interesting results obtained in animal models of passive immunotherapies developed according to the “amyloid-beta cascade hypothesis” and the “Tau hypothesis” are monoclonal antibodies that directly or indirectly target Aβ plaques or neurofibrillary tangles. Unfortunately, these therapeutic antibodies cannot replicate their promising effects on humans at the clinical phase. Despite this, we still hope to learn from these failures and to explore new pathways. The great effects obtained in animals with passive immunotherapy suggest that this technology may be an important key to curative treatment. The remaining challenge is to find a way to achieve the same encouraging results for humans. Alzheimacy expects to join hands with global partners to focus on the development of therapeutic antibodies for Alzheimer’s disease (AD) and continue to fight against this disease.</em>
