Guys please help. This is urgent! Q1) An immersion heater is put into some crushed ice at 0°C. The immersion heater is switched on.

On Fig 5.2, sketch the graph of temperature against time, up to the time when all the ice has melted.

NOTE: the dotted line on the graph is the time when all the ice has melted.

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.

Two trains leave a station at the same time, train a travels at a constant speed of 16 m/s. train b starts at 8.0 m/s but accelerates constantly at 1.0 m/s squared. after 10.0 seconds, which train has the greater speed?
