Answer:
The correct answer is - c. Spaceship will have a velocity to the East and will be slowing down.
Explanation:
In this case, if turned on thruster #2 then it will exert force on the west side as thruster 2 is on the east side and it can be understood by Newton's third law that says each action has the same but opposite reaction.
As the spaceship engine applies force on the east side then according to the law the exhauster gas applies on towards west direction. It will try to decrease the velocity of the spaceship however, the direction of floating still be east side initally.
Answer:
D
Explanation:
In order to disprove an old theory you need to prove a new one that contradicts it using scientific research and experimentation
Answer:
A wave is a disturbance of the space (or of a medium), that carries energy without transmitting matter.
A wave is produced when there is a periodic vibration in the particles of a medium (mechanical wave), or when there is a periodic oscillation of the electric and magnetic fields (electromagnetic waves). Electromagnetic waves are the only ones that can travel through a vacuum.
Mechanical waves are further classified into two types, depending on how the particles in the medium vibrate:
- If they vibrate up and down (perpendicular to the direction of motion of the wave), they are called transverse waves
- If they vibrate back and forth (parallel to the direction of motion of the wave), they are called longitudinal waves
In general, waves are generated from a precise point in the space, which is called source of the wave. The source of the wave does work, since it is responsible for starting the motion of the particle, and make them starting vibrating, so it transmits energy to the particles.
