After a student shoves a book across a flat table, it begins to slow down. Why?
Dovator [93]

Answer:

  • <u>The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object. The frictional force from a fluid is called a drag force.</u>

Which characteristic do arid and polar regions share?
Setler79 [48]

few plants

Explanation:

Arid and polar regions of the world typically have few plant species. The plant species in such environment are called xerophytes. They are plants that can live in an area with little to no precipitation.

  • Arid regions of the world are about the most driest in the world with very high diurnal temperature range.
  • Polar regions are frigid and cold all year round.
  • Both arid and polar regions have little to no precipitation all year round.
  • They have poor soils to support plant growth.
  • This is why they both have few plants.

A particle has a de Broglie wavelength of 2.1 × 10-10m. Then its kinetic energy increases by a factor of 3. What is the particle
svlad2 [7]

Answer:

\lambda' =1.21\times 10^{-10}\ m

Explanation:

given,

de broglie wavelength of the particle = 2.1 × 10⁻¹⁰m

Kinetic energy increase factor = 3

de broglie  wavelength of new particle = ?

we know,

P = \dfrac{h}{\lambda}

Kinetic energy

K =\dfrac{p^2}{2m}

K =\dfrac{h^2}{2m\lambda^2}...........(1)

Kinetic energy of other particle

3K =\dfrac{h^2}{2m\lambda'^2}............(2)

dividing equation (1)/(2)

\dfrac{1}{3} =\dfrac{\lambda'^2}{\lambda^2}

\lambda' = \dfrac{\lambda'}{\sqrt{3}}

\lambda' = \dfrac{2.1\times 10^{-10}}{\sqrt{3}}

\lambda' =1.21\times 10^{-10}\ m
