Answer:
D). 
Explanation:
As we know that temperature scale is linear so we will have
now we have
so the relation between two scales is given as
now we know that in kelvin scale the absolute temperature is 600 K
so now we have
so correct answer is
D).
Answer:
False is the correct answer.
It is considered more of a chemical change because all of the cells inside the plant decompose (change chemicaly)
Answer:
60m
Explanation:
According to one of the equation of motions, v² = u²+2as where;
S is the distance
u is the initial velocity
v is the final velocity
a is the acceleration
Since the arrow is shot upwards, the body will experience a negative acceleration due to gravity i.e a = -g
Therefore our equation will become;
v² = u² - 2gS
Given u = 40m/s, g = 10m/s², S = 75m
Substituting to get the final velocity of the arrow we will have;
v² = 40²-2(10)(75)
v² = 1600 - 1500
v² = 100
v = √100
v = 10m/s
Total distance traveled is speed of the object × time taken
Total distance traveled = 10 × 6
= 60m
The arrow has therefore traveled 60m after 6seconds
Answer:
Work done in both the cases will be same
Explanation:
As we know that the work done against gravity is given as
here we know that gravitational force is a conservative force and the work done against gravitational force is independent of the path
So here the work done by person to move the object between two different heights will be independent of the path they choose
So for the first person and second person will be same in both the cases because the height through which the boxes are transferred will be same in both the cases
