Answer:
L = 3.51
Explanation:
Pendulum equation is T = 2pi
T = 1.5 and we are solving for L
1.5=2
square both sides to get 2.25 = 2
multiply both sides by 9.81 then divide by 2 and 3.14 as a substitue for pi. The answer should be about 3.51 in length
L = 3.51

The sine of an angle is (opposite side) / (hypotenuse) .
Multiply each side by (hypotenuse, and you have
Opposite side = (hypotenuse) x (sine of the angle) .
Sin(12°) = 0.2079...
Opposite side = (52 m) x (0.2079)
= 10.81 meters .
on the globe , the largest continent on earth , asia lies in between eastern and northern hemisphere. it is also known that country china comes in asian continent. hence we can say that china also lies in between eastern and northern hemisphere.
hence the two hemispheres are northern and eastern.
Answer:
Explanation:
For unbanked road the maximum friction force will provide centripetal force to the car.
So here we will have
Since we know that centripetal force here is due to friction force
now for two cars we will have
also we have
now by division of two equations
so we will have
