On souhaite mesurer l'intensité du courant électrique qui traverse la lampe dans chaque montage (fig 1 et fig 2). reproduit les schémas en ajoutant l'appareil nécessaire pour mesurer l'intensité et indiqué les bornes<A et Com>

Are the results of a thoroughly tested hypothesis?

If you fill your car tire to a pressure of 32 psi (pounds per square inch) on a hot summer day when the temperature is 35°c (95°f), what is the pressure (in psi) on a cold winter day when the temperature is -15°c (5°f)? assume no gas leaks out between measurements and the volume of the tire does not change.

For a reaction delta h= -286 kj. when is the reaction spontaneous a: when t delta s = 2(-286 kj) b: when t delta s= -286 kj c: when t delta s < -286 kj d: when t delta s > 0
