see bahubali picture and pushpa this is your answer Visit your school library, read newspapers and discuss with your elders in your family to get information related to various activities, campaigns and news items about animal welfare. You can also do web search using keywords like endangered animals, animal rights, animal welfare, etc. Write a note of about 300-400 words describing the facts on the animal. Draw/paste picture as suitable. Note the following points: 1. animal in concern 2. year of origin of the project/activities/campaign, etc. 3. information regarding the animal 4. human-animal relationship
Answer:
number 1 is b and and number two d
Explanation:
<span>The round trip is 12.5 miles * 2 way = 25 miles. In order to accomplish this in 45 minutes, or 45/60 = 0.75 hours, Tyrone would have to drive at a speed of 25 miles / 0.75 hours = 33.3 miles per hour. If he were to actually be able to drive continuously at this speed without stopping and the prescription pickup were instantaneous, then he would be able to make the round trip in time. However, in the real world this is unlikely to be the case.</span>
The half-life of the reaction is 101.9 min
<h3>First order reaction </h3>
When a reaction's pace and reactant concentration are inversely correlated, the process is known as a first-order reaction. To put it another way, the reaction rate doubles when the concentration does. One or two reactants can be present in a first-order reaction, as in the case of the decomposition process.
<h3>The half-life of first-order reaction:-</h3>
The amount of time it takes for the initial concentration of the reactant(s) to decrease by half is known as the half-life of a chemical reaction (abbreviated as "t1/2").
<h3 /><h3>Calculation:-</h3>
a→b
25% reacted means 75% remains
t=42 min
Rate constant
k=(2.303/t)(log a/a-x)
k=(2.303/42)(log 100/100-25 )
k=(0.054) (log 100/75)
k=(0.054)(0.1249)
k=0.0068 per min
half life
t1/2=(0.693/k)
=(0.693/0.0068)
=101.9 min

Answer: Option (d) is the correct answer.
Explanation:
A metal which has the largest size and the most valence electrons would have the highest conductivity because the larger is the size of a metal the more freely electrons can move in it. Hence, the metal can conduct electricity.
If the atom is smaller in size then the electrons will be tightly held around the nucleus and hence they won't be able to move freely. Therefore, they will not conduct electricity.
Thus, we can conclude that the atom with the largest radius and the most valence electrons would have the highest conductivity.
