<span>A rocket in its simplest form is a chamber enclosing a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction. A good example of this is a balloon. Air inside a balloon is compressed by the balloon's rubber walls. The air pushes back so that the inward and outward pressing forces are balanced. When the nozzle is released, air escapes through it and the balloon is propelled in the opposite direction.</span>
the answer is true acceleration is the change in distance over time.
hope this helps
Answer:
Convex or converging lens.
Because they help to magnify the image or increase the size of the image you are viewing when light is reflected on it or to make the quality of the image clearer to view.
Explanation:
They both make use of Convex or converging lens.
Both lenses are very important because they help to magnify the image or increase the size of the image you are viewing when light is reflected on it or to make the quality of the image clearer to view.
The correct options are:
<span>B. Radiation is heat flowing in waves.
C. Conduction is heat flowing between two objects that are touching each other.
In fact, radiation is heat transferred by electromagnetic waves, while conduction is the heat transfer between touching objects (the particles of one object collide with the particle of the other object, and so heat is transferred via the transfer of kinetic energy between the molecules).
Instead, option A is wrong (because conduction </span>is the heat transfer between touching objects) and option D is wrong because convection is the heat flowing when a liquid or a gas carries the heat.
Answer:
An X-ray is used to take pictures of your bones. The waves that are used are known as radiation waves.
