In-s [12.5K]3 years ago
4 0

Answer:

A. Distance = 18 m

    time = 2 hr

    speed = 9 m/hr

Explanation:

Speed is the same thing as velocity.

Velocity = distance/time

18m/2hr = 9m/hr

For choice B, the numbers are right, but the units are mixed (minutes were changed to hours)

Answer:

See explanation

Explanation:

According to Louis de Broglie, matter has an associated wavelength. He was the first scientist to establish the idea of wave-particle duality or wave- particle paradox.

The display of wavelike properties by objects in the universe is dependent on the magnitude of the of the mass of the body. Small objects have a large associated wavelength and can be described completely by quantum mechanics.

A buckyball with a mass of 1.2 x 10-21 g, 0.7 nm wide, moving at 38. m/s has a very small mass and significant associated wavelength hence the system can be completely described by quantum mechanics.
