The first satellite to capture a photograph of Earth from space was Explorer 1, launched on January 31, 1958. This and subsequent space missions like the Apollo program expanded our visual understanding and perception of our planet.
The first satellite to give us a photograph of the Earth from space was Explorer 1, launched on January 31, 1958. Prior to Explorer 1, the Soviet Union had launched Sputnik 1 in October 1957, but Explorer 1 was the first satellite to provide us with images of Earth from space. This marked a significant moment in human history, altering our perception of the planet.
Later on, the Apollo program further improved our visual understanding of Earth, with the Apollo 17 mission capturing the 'Blue Marble' - one of the rare full disk images of the Earth in sunlight. Such images underscored our perception of Earth as a small, yet interconnected and strikingly beautiful, celestial body floating in the vastness of space.

propulsion is an example of which Newton's Law?
A. 1st Law
B. 2nd Law
C. 3rd Law
D. All of Newton's Laws
Squids and octopuses forcefully expel water through the siphon after ingesting it, propelling themselves through the water. Third Law of Newton.
His third law asserts that there is an opposite and an equal response in nature for every action (force). When an object A pulls on an object B, the opposite force is applied to the first object by object B. Alternatively said, interactions lead to forces.
There are numerous real-world applications of Newton's third motion law. For instance, when you leap, the earth exerts an equal and opposing reaction force that propels you into to the air. This is because when you apply a force to it with your legs, it responds in kind. Rockets and other projectiles are designed using Newton's third law by engineers.

car and bowling ball
There is no gravitational force between any of these pairs of objects.
IF all the pairs are separated by the same distance, then it's the car and the bowling ball.
If I can move them as far apart as I want, then I can make ANY of them have the greatest gravitational attraction between them.

Commutator is part of a motor causes its electromagnet to turn in the same direction consistently, transforming electrical energy into mechanical energy.
Energy is the ability or capability to do tasks, such as the ability to move an item (of a certain mass) by exerting force. Energy can exist in many different forms, including electrical, mechanical, chemical, thermal, or nuclear, and it can change its form.
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators.
