The type of clock that has a numbered dial and moving hand(s)

A certain pendulum clock with a 12 hr dial happens to gain 1 min/day. After setting the clock to the correct time how long it will take to indicate correct time again?

Masses m , 2m , 3m , 4m ,………, 12m are kept on the peripheri of a clock having a circular dial. The masses are kept such that m is kept at 1 , 2 , 3m at 3 ……… 12m at 12 . vec g is the gravitational field intensity at the centre of dial.

A clock face has charges -q, -2q, ,.....-12q fixed at the position of the corresponding numerals on the dial. The clock hands do not disturb the net field due to point charges. At what time does the hour hand point in the direction of the electric field at the centre of the dial.

The time represented by the clock hands of a pendulum clock depends on the number of oscillations performed by pendulum. Every time it reaches to its exterme position the second hand of the clock advances by one second that means second hand moves by two second when one oscillation is completed. (a) How many number of oscillations completed by pendulum of clock in 15 minutes at calibrated temperature 20^(@)C (b) How many number of oscillations are completed by a pendulum of clock in 15 minutes at temperature of 40^(@)C if alpha = 2 xx 10^(-5)//"^(@)C (c ) What time is represented by the pendulum clock at 40^(@)C after 15 minutes if the initial time shown by the clock is 12:00 pm? (d) If the clock gains two seconds in 15 minutes in correct clock then find-(i) Number of extra oscillations (ii) New time period (iii) change in temperature.

At 10 O' clock the hands of a clock make an acute angle and a reflex angle. Find the measure of each of these angles

At 2o'clock, the hands of a clock make an acute angle and a reflex angle. Calculate the size, in degrees, of each of these angles

At 10o' clock, the hands of a clock make an acute angle and a reflex angle. Calculate the size, in degrees, of each of these angles

The gene for right handedness is dominant over the gene for left handedness. Most probable gene types of two right handed parents with left handed child is
