Very very roughly, an Earth month.
The Sun isn't solid, so it doesn't all have to rotate at the same rate. Different latitudes actually rotate at different speeds. One complete rotation is about 24 days at the Sun's equator, but 35 days near the poles !
Answer:
P = 22 watts
Explanation:
Given that,
The output power of the generator = 2 a
The output potential difference = 11 V
We need to find the output power of the generator. The formula for the output power is given by :
So, the output power of the generator is equal to 22 Watts.
Answer:
b
Explanation:
When an object is in circular motion, the direction of velocity is in the direction of tangent to the circle and acceleration is always directed towards the radial direction. This means that velocity is always perpendicular to acceleration of the object.
Hence option (b)-The velocity and acceleration vectors are perpendicular is correct.
<span>A tidally locked body in synchronous rotation (the moon) takes just as long to rotate around its own axis as it </span>does<span> to revolve around its partner (the earth). In other words, the moon spins on its axis at the same rate it orbits the earth.</span>
<h2>Answer: The planets formed at the center of a collapsing spinning cloud of gas and dust.</h2>
The most accepted theory so far, in relation to the formation of our solar system is that it was originated by the contraction of a cloud of interstellar gas due to its own gravity.
To understand it better:
According to this theory, a cloud of gas and interstellar dust began to shrink due to its own gravity. This led to the increase in the temperature of the system, which began to rotate forming a large gas sphere in the center (the Sun) with a flat disk around it.
This is how the Sun formed from the sphere in the center and the planets formed from the disk orbiting in the same plane.
