Pls answer - A driving instructor gives a student a sudden order to stop the car in the shortest possible time.
Fig. 1.1 above shows the speed-time graph of the motion of the car from the moment the order is given.

(a) The order to stop is given at time t = 0 s.
(i) State the speed of the car at t = 0 s.
(ii) Suggest why the car continues to travel at this speed for 0.9 s.

(b) Calculate
(i) the deceleration of the car between t = 0.9 s and t = 4.0 s.
(ii) the total distance travelled by the car from t = 0 s.

(c) Describe and explain a danger to a driver of not wearing a safety belt during a sudden stop.

(science)study the following ocean currents map. an ocean currents map is shown. on the map the locations for san diego, california and savannah, georgia are marked. there is a looping current from the north past san diego and a looping current from the south near savannah which statement is most likely correct about the average temperatures in san diego, california as compared to savannah, georgia? it is higher in savannah because of the cool ocean currents from the south. it is higher in savannah because of the warm ocean currents from the north. it is lower in san diego because of the warm ocean currents from the south. it is lower in san diego because of the cool ocean currents from the north.

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

You can melt ice by applying pressure because the solid/liquid line has a slope.
