Two forces of equal magnitude are acting simultaneously on a particle at an angle of separation between them 120 degrees.Find the resultant vector.I want to know about the concepts of logarithm. I have seen some practise question on the dashboard but they are of high level. And even still it is not clear to me that how we can find the values in a question through log, and please also provide me its table. Because it is quite difficult to understand and solve the practice question of logarithm.

waiting for your reply.

thanks

have a good day

Find the height of the cylinder of maximum volume that can be inscribed in a sphere of radius a

v = dx / dt = 3t + 2

Determine the distance (x) travelled by the body in time (t) using the method of integration.

^{1/2}+tan1) (31/2+tan2) (31/2+tan3) ..... (31/2+tan29)=The velocity of a particle depends upon the time t according to the equation:v= (√ab)+bt + c/d+t.

The physical quantites which are represented by a,b,c and d, are in the following order:

a) distance,distance, acceleration,time

b)distance,acceleration, distance,time

c)acceleration, distance, distance, time

d) none of these

Given that and

A^{2}+B^{2}=R^{2}then angle between and will be?differentiation by chain rule: y= 2sin(omegax+phi) where omega and phi are constant

Given that A=B=C. If A+B=C then the angle between the vector A and vector C isθ_{1}. If A+B+C=0, then the angle between vector A and vector C isθ_{2}. What is the relation betweenθ_{1}and θ_{2}?a)θ

_{1}= θ_{2}b)θ

_{1}= θ_{2}/ 2c)θ

_{1}= 2θ_{2}d) none of these

^{x/log x}36. To a person going east in a car with a velocity of 25 km.p.h. a train appears to move towards north with a velocity of $25\sqrt{3}$ km.p.h. What is the actual velocity and direction of motion of the train ?

[Ans. 50 km.p.h. $30\xb0$ east of north ]

37. A ship A is travelling at 12 km.p.h. in still water in a direction due east. A man on it observe another ship B due north of him which appears to moving directly towards him at a speed of 15 km.p.h. Find the actual speed of B and its direction of motion.

$\left[Ans.19.21km.p.h.;38\xb040\text{'}westofnorth\right]$

38. A cyclist moves horizontally at 10 km.p.h. There is no wind and rain drops appear to him to fall at an angle of $10\xb0$ to the vertical. Find the speed of the rain drops. [Ans. 56.71 km.p.h.]

39. T a person going westward with a velocity of 6 km.p.h.rain appears to fall vertically downward with a velocity of 8 km.p.h. Find the speed of the rain drops.

$[Ans.10km.p.h.,36\xb0-52\text{'}westofSouth]$

^{2}a+sin^{2}b=sinc then possible values of c areVector A is directed along north and vector B is directed along south-west. If C = A + B, then which of the following relations is correct?a) C must be equal to |A+B|

b) C must be greater than |A+B|

c) C must be greater than |A-B|

d) C must be equal to |A-B|
