Bonjour pouvez vous m'aider SVP. Le réservoir d'une voiture contient 54L d'essence. Cette voiture consomme 7L d'essence pour parcourir 100km. Le voyant d'essence de la voiture s'allume pour indiquer qu'il faut faire le plein lorsqu'il reste 5L dans le réservoir. Quelle distance peut-elle parcourir avant que l'indicateur s'allume?

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

What object a collides with object b and bounces back its final momentum is?

When using the scientist method, which step comes last?
