3. A fixed point O lies on a straight line. A particle P moves along the straight line. At time t seconds, tgeqslant 0 the distance, s metres , of P from O is given by s=(1)/(3)t^3-(5)/(2)t^2+6t (a) Find the acceleration of P at each of the times when P is at instantaneous rest. (b) Find the total distance travelled by P in the interval 0leqslant tleqslant 4

When there's a temperature difference between two objects, heat is transferred from the hotter object to the cooler one. What is the name for the state reached when they are both at the same temperature?

The graph shows the relationship between the mass of an object and its specific heat capacity. Assuming the temperatu re change is 20^circ C calculate the change in internal energy when the mass of the object is 20kg. Give your answer in kJ and to 2 decimal places if needed. square square square square square square square square square square square
