1) consider a car of mass m=1215 kg that is moving up a=θ =12 hill All constant speed V =36 km/h as shown on the figure below. * The total resistive force (road friction and air resistance ) acting on the car for the speed is given by FR=1500 N and the height of the hill is h =12 m.

a) what power must be delivered by the car engine to travel the car of the constant speed ?

b) How much work is done by the force obtained from the car engine until the car reaches the top of the hill?

c) How much work is done by the resistive force until the car reaches

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

the rearrangement of particles in a physical change. hope this
