If a 2,300 kg car is accelerating at 16 m/s^2, what is the force it is producing?

Answers

Force = (mass) x (acceleration)

In order to acceleratethe car at that rate, a force of

(2,300 kg) x (16 m/s²) = 36,800 newtons
(about 8,270 pounds ... 4.14 tons !)

has to be coming from somewhere ... presumably from the straining,
screaming, smoking engine under the hood.

The force it might apply to an object it runs into will depend on the
shape and composition of that object.

Water changes shape to fill the shape of its container. what is the best explanation for this ?

Answers

The answer would be that it is a liquid. It does not have a definite shape. That is why is takes the shape of what ever container it fits into.

Liquids don't have a definite shape so that means it does not take shape of its contaner but, solids do for example when you put water in a bown and freeze it up then it will stay there. Hope i helped :D

When birds remain airborne and moving without flapping their wings, on what are they gliding?

Answers

The birds can glide in the air without moving their wings by maintaining the thrust of the air by their weight and move downward at a very slower rate.

Further Explanation:

The birds have a capability of flying high in the air without flapping their wings and still not falling down rather they glide downwards due to the up thrust of the air. This technique of the birds to keep them in the air without flapping their wings is termed as soaring.

The soaring birds make use of the air current and its thrust on their primary wings so that there is no turbulence experienced by them due to the pointed tips of their primary wings.

The birds should possess some mass in order to maintain a balance between the thrust and the weight of their body. That’s why the small birds are not able to maintain their flight but the bigger birds like vulture, eagle etc. experience sufficient air drag in order tio maintain their flight.

Thus, the birds can glide in the air without moving their wings by maintaining the thrust of the air by their weight and move downward at a very slower rate.

In which of these materials does sound travel most slowly air,steel,glass,water

Answers

Sound travels the slowest through air, and the fastest through steel. This seems counter-intuitive, since sound seems clearer through air than it does through a solid like steel, but there is reasoning behind it. Since steel is a solid, the particles within it are more closely packed than in a liquid like water or the gases in air, in which the particles are farther apart even than the water. Sound waves don't have as much distance to travel between particles in solids as they do in liquids or gases, in which the particles are farther apart. Because of this, the sound waves can travel the quickest through solids. The only reason sound travels more quickly through steel than glass is because steel is a crystalline solid, while glass is an amorphous solid. Without getting into the specifics, the difference between a crystalline and an amorphous solid is that an amorphous solid's particles are farther apart than a crystalline solid's, which is why glass doesn't keep its shape as well as steel does. Because of this, sound travels more quickly through steel.

So, to recap, sound travels through air, steel, glass, and water in the following order, with 1 being the slowest and 4 being the quickest:
1. air
2. water
3. glass
4. steel

The one is air.It is air because you dont feel the air and sometimes it moves slowly
