The planet Mercury travels in an elliptical orbit with eccentricity 0.206. Its minimum distance from the sun is 4.6 ⨯ 107 km. Fi

sergeinik [125]

Answer:

$a=5.16\times 10^{7}\ km$

Explanation:

It is given that,

The planet Mercury travels in an elliptical orbit with eccentricity 0.206, e = 0.206

The minimum distance from the sun, $b=4.6\times 10^7\ km=4.6\times 10^{10}\ m$

The relation between the minimum and the maximum distance from the sun is given by :

$e=\sqrt{1-\dfrac{b^2}{a^2}}$

a is the maximum distance from the sun

$a^2=\dfrac{b^2}{1-e}$

$a^2=\dfrac{(4.6\times 10^{10})^2}{1-0.206}$

$a=5.16\times 10^{10}\ m$

or

$a=5.16\times 10^{7}\ km$

So, the maximum distance from the sun is $5.16\times 10^{7}\ km$ . Hence, this is the required solution.

A uniform electric field of magnitude 365 N/C pointing in the positive x-direction acts on an electron, which is initially at re

Ede4ka [16]

Answer:

$W= 1.752\times10^\left ( -18\right )$ $Joules$

Explanation:

given E= 365 N/C in positive x-direction

electron initially at rest q= 1.6 $\times10^{-19}$ C

force experienced by the electron F= Eq

⇒F= 365 $\times1.6\times10^{-19}$

=584 $\times10^{-19}$

Distance traveled by electron S = 3 cm

now work done W= F $\times$ S=584 $\times$ $10^{-19}$ $\times3$ $\times10^{-2}$

W= 1752 $\times10^\left (-21 \right )$ Joules

Work done= 1.752 $\times10^\left (-18 \right )$ Joules

The light incident on a smooth reflecting surface undergoes specular reflection. The angle of reflection is 55°. What can you sa

Serggg [28]

The correct answer is letter C. The angle of incidence is equal to 55 degrees. This is because Specular Reflection refers to mirror-like reflection of light or other kinds of waves from a surface. This phenomenon is where light from a single incoming direction is also reflection in a single-outgoing direction.

What should be angle between force and displacement to get the maximum work

aleksandrvk [35]

Answer: The angle between force and displacement should be θ = 90° for minimum work. The angle between force and displacement should be θ = 0° for maximum work.

What is the form of the main energy output from the reactor?

Anna007 [38]

Explanation:

A nuclear reactor produces and controls the release of energy from splitting the atoms of certain elements. In a nuclear power reactor, the energy released is used as heat to make steam to generate electricity.
