The seat belt is applying a force in the opposite direction.
Answer:
Because the wavelengths of macroscopic objects are too short for them to be detectable.
Explanation:
Wavelength of an object is given by de Broglie wavelength as:

Where, 'h' is Planck's constant, 'm' is mass of object and 'v' is its velocity.
So, for macroscopic objects, the mass is very large compared to microscopic objects. As we can observe from the above formula, there is an inverse relationship between the mass and wavelength of the object.
So, for vary larger masses, the wavelength would be too short and one will find it undetectable. Therefore, we don't observe wave properties in macroscopic objects.
The answer is b. According to the law of conservation of energy, energy can never be created nor destroyed, only transferred from one form to another.
Answer:
collagen and protein
Explanation:
Made mostly of collagen, bone is living, growing tissue collagen is a protein that provides a soft framework and calcium photosphate site is a material that adds strength to hardness the framework.
Explanation:
The distance traveled north ward = 2 miles
distance traveled south ward = 3miles
Displacement is the distance traveled in a specific direction. So, it depend on the start and finish point.
The displacement = 3 miles - 2miles = 1mile southward
Distance is the total length of path;
Distance = 3 miles + 2 miles = 5miles
