Time-weighted return. Related Articles. Time-weighted returns is a measure of the compound rate of return of a portfolio over a stated period of time. It requires a set of sub-period returns to be calculated whenever there is an external cash flow, such as a deposit or withdrawal from the portfolio.
Posted on. (Answer #1). For a simple pendulum, where the pendulum is itself considered of negligible mass which moves with a minimal amplitude, the time period is given by the formula. T = 2(pi)*(sqrt(L/g)). where T is the time period, L is the length of the pendulum, and g is the gravitational constant.By lengthening the pendulum, the weight at the end must travel a longer distance as it swings, which means more time is required for it to complete a given period. = 2(pi)*(sqrt(L/g)). where T is the time period, L is the length of the pendulum, and g is the gravitational constant.
