Answer:
Which one of the following shows the equation x = – 3 in two variables equation?
Principal P=Rs.4,000. Since the interest is compounded half-yearly the number of conversion periods in 1
1
/2
years are 3. Also the rate of interest per conversion period (6 months) is 10%×
2
1
=5%(0.05 in decimal).
Thus the amount A
n
(in Rs.) is given by
A
n
=P(1+i)
n
A
3
=4,000(1+0.05)
3
=4,630.50
The compound interest is therefore Rs. (4,630.50−4,000)
=Rs.630.50.find find the amount and CI in the following compound annual 1) P = ₹ 44100, R = 10% N = 1/1/2yearsn order to find the change in time period of rotation we need figure out what’s the change in angular velocity.
Let's use i,w,r and I, W,R to denote the moment of inertia ,angular velocity and radius before and after the transformation.
Now applying conservation of angular momentum(L)
iw=IW
Now moment of inertia of a sphere is 2/5 r^2
Here since mass remains same , we can say moment of inertia is proportional to radius^2
Therefore , W/w= i/I
W/w=(r/R)^2
Substituting R=2r
We get W = w/4
ie the angular velocity became one- fourth the initial value.
Now Time period , T/t =(2*3.14/W) /(2*3.14/w)
This will give T =4t.
ie Time period will quadriple.
The sun will take 108 days to rotate around it's axis if it's radius doubles.the sun is considered as a sphere whose time period of rotation about its own axis is 27days.the sun is shrinked suddenly to half of its original sizewhat will be the new time period
Answer:
it's some time good and another time it will be bad
