Ipatiy [6.2K]

If it increased its speed steadily at a constant rate, then the average speed for the minute was

(1/2)(10m/s + 20m/s) = 15 m/s .

Rolling at an average speed of 15 m/s for 1 minute (60 seconds), it travels

(15 m/s) (60 sec) = 900 meters

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

When transiting a great distance a Navigator prepares a __________ track so the ship can steady courses while driving the shorte
coldgirl [10]

Answer:

composite track

Explanation:

To travel an incredible circular track, the guide must constantly change course because the extraordinary circular track is a turn when plotted on a Mercator map. It is ridiculous to try to navigate an incredible circular route. All things considered, to make the best use of the shorter cruise separation from the extraordinary circular runway, pilots generally divide an incredible hover runway between the underlying position and the target into many much smaller sections ( for trajectory purposes) of approximately one to several days of cruising time (based clearly on the specialty and conditions) and making course changes every day simultaneously, generally in the early afternoon. Absolute separation is thus the set of separations of these fragments determined by the methods of Mercator Sailing. A potential problem with the incredible circular track, however, is the most limited route between two areas, similarly for most tracks closer to the well (or at a higher range) than the two points, starting point or goal. The high areas are often in danger due to the terrible climate and icing. A protected thought of a veteran sailor is to set a range limit for the long voyage plan. This arrangement is called an extraordinary composite circle course arrangement, terminated with way points. This minicomputer soothes the monotonous procedure for deciding these way points for travel.
