Answer:
Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum).
Answer:
4
Explanation:
Humans can detect light and sound, also light and sound travel in waves. Light is faster than sound but sound waves cannot travel through space because there is no medium for the sound waves to travel through.
The answer is 72.2 to 3 significant figures
Answer:
Decomposers that recycle matter back into the food chain.
Explanation:
All dead organisms are food for decomposers. Decomposers that recycle matter back into the food chain.
Answer:
F = 141.3 N
Explanation:
Pressure inside the Champagne bottle = 4.5 atm
1 atm = 10⁵ Pa
4.5 atm = 4.5 x 10⁵ Pa
inner radius of the bottle = 1 cm = 0.01 m
Area of the bottle = π r²
= π x 0.01²
= 3.14 x 10⁻⁴ m²
Force acting on the cork due to excess pressure
F = P A
F = 4.5 x 10⁵ x 3.14 x 10⁻⁴
F = 141.3 N
The frictional force on the cork due to the neck bottle will also be equal to F = 141.3 N
