How do Earth's shape, orbit and the tilt of its axis determine the seasons?

1 answer:

5 0

Answer: The seasons are caused as the Earth, tilted on its axis, travels in a loop around the Sun each year. Summer happens in the hemisphere tilted towards the Sun, and winter happens in the hemisphere tilted away from the Sun. That's why days are longer during the summer than during the winter.

ra1l [238]

Answer:

a) $I=0.012\ kg.m^2$

b) $I=0.012\ kg.m^2$

Explanation:

Given that:

mass of rod, $m=0.4\ kg$

length of the rod, $l=0.6\ kg$

<u>Moment of inertia of rod about its center and perpendicular to the rod is given as:</u>

$I=\frac{1}{12} m.l^2$

$I=\frac{1}{12} 0.4\times 0.6^2$

$I=0.012\ kg.m^2$

(b)

<u>Moment of inertia on bending the rod to V-shape of 60 degree angle and axis being perpendicular to the plane of V at the vertex.</u>

<em>We treat it as two rod with axis of rotation at the end and perpendicular to the plane of rotation. </em>

<em>So, the mass and the length of the rod will become half of initial value.</em>

$I=I_1+I_2$

$I=\frac{1}{3} \frac{m}{2} (\frac{l}{2})^2 +\frac{1}{3} \frac{m}{2} (\frac{l}{2})^2$

$I=2[ \frac{1}{3}\times 0.2\times 0.3^2]$

$I=0.012\ kg.m^2$

What will the transistor look like in the future

Elden [556K]

<u>TRANSISTOR:</u>

The future of transistors based on the ongoing researches suggests that, it would be based on nano technology. This technology is itself still under development and the case is similar in the case of transistors too.

Transistors due to their applications, especially its application as an amplifier has increased its usage and the dependability over them. The hard part often arises with the fabrication techniques which are being tested and developed as we speak in order to increase the efficiency of the transistors and also to reduce their physical size though, these would mean that, the design complications would be higher.

Which terms describe the different movements of earth? check all that apply. rotation revolution tilted orbit lunar cycle ellipt

gogolik [260]

Revolution and rotation are the terms that describe the different movements of the earth.

<h3 /><h3>What is the earth?</h3>

Our home planet is Earth. Earth and its moon, according to scientists, originated about the same period as the rest of the solar system.

That would have been around 4.5 billion years ago, according to scientists. Earth is the solar system's fifth-largest planet.

The rotation and revolution of the earth are two different movements. The movement of the earth on its axis is known as rotation.

Revolution is the movement of the earth around the sun in a fixed route or orbit. The earth's axis, which is an imaginary line, forms a 6612° angle with its orbital plane.

Hence revolution and rotation are the terms that describe the different movements of the earth.
