A
B ofcourse
If the book says A , its wrong!
B because the sign shows direction
No idea abt the last one!
al what I have done is the same but the disastrous book tooooo wrong atm

Hmm, but its vague.....yes no neutrons... as hydrogen atom does not have any neutron but have protons ... an any nucleus shud atleast have a proton...
the work done ratio will be 1:1. Work donot have any direct link with time but im not sure about it.
in projectile motion, horizontal component of velocity remains constant only.
in the lift, man will weigh 1470 N. The apparent weight of man will increae.
The answer to the combustion analysis question is D- 50% KOHon which oof the following does the final shape of protien depends
a.primary structure
b.quarternary structure
c. both
d. none
in combustion analysis CO2 is absorbed ina-mg(ClO4)2b-lime waterc-concentrated H2SOd-50%KOH Insulin preparation comes under which branch of biologya) Social Biologyb) Biotechnologyc) Genetic Engineeringd) ParasitologyUnicellular Plasmodium is studied under the branch of biology calleda) Microbiologyb) Cell Biologyc) Parasitologyd) Pathology
the friction btween 2 surfaces depends upon yhe normal frce, it is independatnt of ?????
a) co-officient of kinetic energy
b) co-officient of static friction
c)area f contact between the two surfaces
d)friction
an acceleration of 1 ms-2 by a body of 1 kg is produced by the force of???
a)one pound
b)one newton
quantities which can be specified by a number havng apropriate units(positive negative. zero) are called..
a)scalers
b)vectors??
unit of solid of angle is???
a)steradian
b)radian
c)degree
d)radian-second
CAn any one clearify me these??? as i am too much confused aftr seeing ans. in ECAt book
The answer is 6i cnt solve it.....shud i convert it to row echelon form.....
how.....wats the trick heere
Friction is independent of area of contact. I was pretty confused about this too about a month ago , but our Sir says that it is independent of area of contact
And solid angle's unit is "Steradian"
Lol i don't exactly remember what the whole logic was behind it. I'll have to search my notes for it. I'll post the whole logic after 14th when i'm done with my practical examswell means increasing the surface area wil not cause any increae in resistance in moving the object?????
its not 0 joules..........The answer to the combustion analysis question is D- 50% KOH
And the answer to the change in energy question is 0 J
well increasing area must have an effect..........its so obvious.....how that teacher cn say nowell means increasing the surface area wil not cause any increae in resistance in moving the object?????
well 32 must be B ISNT it smz imran ....mayb book is wrong.....Q32:
X litres of carbon monoxide is present at S.T.P. It is completely oxidised to CO2. The volume of CO2 formed is 11.207 L at S.T.P. What value is of X in litres ?
A. 22.414 L
B. 11.207 L
C. 5.6035 L
D. 44.828 L
The answer is C but how ?
Q36:
The equivalent weight of a certain trivalent element is 20. Molecular weight of the oxide is
A. 168
B. 68
C. 152
D. 56
The answer is A but how ?
Mine too!isnt this question wrong....none of option is matching.....my ans comes -4-4i
