estion 1 A car travels between two stations, A and B, 4 km from each other. It starts from rest at A and accelerates uniformly until it obtains a speed of 80 km/h. This car maintains until it is uniformly decelerated, coming to a stop at B. The time taken for the whole journey is 5 minutes, and the magnitude of the acceleration is half that of the deceleration. Calculate the acceleration and the distance the car travels at constant speed. ​

Neurons are components of the nervous system of the body that transmit signals as electrical impulses travel along their length. these impulses propagate when charge suddenly rushes into and then out of a part of the neutron called an axon. measurements have shown that, during the inflow part of this cycle approximately 5.6x10^11 na per meter, each with a charge of e enter the axon. how many coulombs of charge enter a 1.10 cm length of axon during this process
