Elements are made up of identical atoms.
Molecules are made up from 2 or more atoms.
Compounds are made up from atoms of at least two elements.
Answer:
law of inertial
Explanation:
state that if anobject is in motion it will continue to move until some external force act on it.
Greater the collision
Explanation:
The greater the speed of gas particles in the containers, the greater the collision of gases with the container and between themselves.
- The speed of gas molecules increases when their kinetic energy increases.
- This causes a surge in collision between the particles and the wall of the container.
- A gas is composed of large number of molecules moving at different speeds.
- When the temperature of gases are increased, they gain more kinetic energy and their speed will increase.
- This leads to an increase in effective collision between gas particles.

When the launch velocity is a bit less than the escape velocity, the satellite with time will find itself back to earth and when the speed is far beyond the escape velocity, the satellite with time, be lost in space.
The velocity of escape from the less massive Moon is about 2.4 km per second at its surface. ... A planet (or satellite) cannot long retain an atmosphere if the planet's escape velocity is low enough to be near the average velocity of the gas molecules making up the atmosphere.
Answer:
True
Explanation:
In 2019 was taken the first image of a supermassive black hole in the center of the galaxy M87 with the Event Horizon Telescope, which is a network of radio telescope located in different points of the Earth, with the purpose of making a telescope of the size of the Earth.
A radio telescope is an antenna that is capable to perceive the light in the radio part of the electromagnetic spectrum¹.
It is important to notice that in the picture what it can be seen is the effect that the black hole has in the nearby stars.
Key terms:
¹Electromagnetic spectrum: decomposition of light in its different wavelengths (from radio waves to gamma rays).
