In a certain clock, a pendulum of length l1 has a period t1 = 0.95s. the length of the pendulum
is adjusted to a new value l2 such that t2 = 1.0 s. what is theratio l2/l1?

Ratio of length will be

Explanation:

We have given time period of the pendulum when length is is

And when length is time period

We know that time period is given by

So ----eqn 1

And -------eqn 2

Dividing eqn 2 by eqn 1

Squaring both side

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
