What will happen to the solar particle as the particles enter magnetosphere?​
saul85 [17]

Answer:

When the solar particles enters into the magnetosphere gets deflected.

Explanation:

When particles enter into the magnetosphere gets deflected because of the solar wind. After getting deflected they comes towards the earth's magnetic field. The Earth's outer space is live and also much dynamic. When solar wind as well as the plasma comes together in magnetosphere, electricity gets generated and also formation of electric field. The magnetosphere found to attract the charged particles only that are being emitted by the sun.

In an experiment, a shearwater (a seabird) was taken from its nest, flown a distance 5220km away, and released. It found its way
denis-greek [22]

Answer:

-4.72005 m/s

0 m/s

Explanation:

Displacement = 5220 km

Time = 12.8 days

The average velocity is given by

v_a=\dfrac{0-5220\times 10^3}{12.8\times 24\times 60\times 60}\\\Rightarrow v_a=-4.72005\ m/s

The average  for the return flight is -4.72005 m/s

When the total displacement is divided by the total time of a journey then we get the average velocity.

Displacement is the minimum distance between the initial and final points of the journey.

Here, the displacement of the whole episode is 0 as the initial and final point is zero.

Hence, the average velocity for the whole episode is 0 m/s

What is the length of an aluminum rod at 65°C if its length at 15°C is 1.2 meters? A. 0.00180 meter B. 1.201386 meters C. 1.2
Deffense [45]

Answer:

Option B is the correct answer.

Explanation:

Thermal expansion

            \Delta L=L\alpha \Delta T

L = 1.2 meter

ΔT = 65 - 15 = 50°C

Thermal Expansion Coefficient for aluminum, α = 24 x 10⁻⁶/°C

We have change in length

          \Delta L=L\alpha \Delta T=1.2\times 24\times 10^{-6}\times 50=1.44\times 10^{-3}m

New length = 1.2 + 1.44 x 10⁻³ = 1.2014 m

Option B is the correct answer.
