The given question is incomplete as it lacks the appropriate options, however, the options related to this question is as follows:
a)Test a composite material in the lab to see how it can be improved.
b)Look into trends of various diseases and their effects on society.
c)Research available drugs for treating illnesses such as cancer and heart disease, as well as the side effects of these drugs.
d)Make a plan for how to conquer a disease with drugs.
Answer:
The correct answer is - b)Look into trends of various diseases and their effects on society.
Explanation:
The young scientist who wants to focus on creating drugs to treat disease must think and look for the diseases that are needed to be treated at the moment or affecting the population most and how it affects the society and then plan how to do it.
So, the scientist needs to check the trends of various disease and their effect on society for developing understanding which disease needs to be cure first and how it affects.
Thus, the most appropriate answer is - option B.
When 400 J of heat are slowly added to 10 mol of an ideal monatomic gas, its temperature rises by 10°C. The work done on the gas is 845J.
The amount of work done on gas depends upon the internal energy change and the heat supplied to the system.
According to First Law of Thermodynamics, the change in internal energy is equal to the work done and the heat supplied to the system.
This is given by:
ΔU = W + Q
where, ΔU is change in Internal energy
W is the Work done
Q is the heat supplied
Given,
Q = 400J
Number of moles, n = 10
Change in temperature, ΔT = 10°C
Cv = 3/2R ; Since, the given gas is monoatomic (R=8.3)
We know that, ΔU = n Cv ΔT
On substituting the values in above formula,
ΔU = 10 × 3/2 × 8.3 × 10
ΔU = 1245J
Using,
ΔU = W + Q
1245J = W + 400
W = 845J
Hence, the work done on the gas is 845J.

Answer:
What type of plant
Where is it mainly found
What are some facts about it?
Answer:
Energy and power are closely related but are not the same physical quantity. Energy is the ability to cause change; power is the rate energy is moved, or used. Energy main article Energy is the ability to create a change, for example, creating motion. Tasks (like lifting a box) require an amount of energy to complete.
