i think its false tell me if im wrong
Explanation:
Answer:
4. To the east
Explanation:
Friction forces always act in the opposite direction that an object tends to move in. In this case, when the truck accelerates to the east, the crate tends to move to the west due to inertia (the tendency for an object to remain at rest or at constant speed). In order to stop the crate from moving, there needs to be a friction force to the east.
Answer:
60°
Explanation:
The scalar product of two vectors with an angle ∅ between them is defined as:
Solving for angle ∅:
Answer:
decreases, but frequency increases.
Explanation:
Wavelength and frequency are inversely proportional, meaning the higher the frequency, the shorter the wavelength, and the lower the frequency, the longer the wavelength.
This force is called the reaction force or also known as the normal force. This is a concept from Newton's Third Law of Motion, which states that for every action, there is an equal and opposite force. This force is what keeps the notebook on place on top of the table. It is the force exerted by the table to the book.
