Hello!

Static electricity occurs due to an imbalance in positively and negatively charged atoms. An example of this is when you take your clothes out of the dryer, and feel a slight sting when touching them. Another example of static electricity is lightning.

Current electricity occurs when there is a constant flow of electrons, such as in plug-operated machinery or anything operated using a battery. :)

Nutka1998 [239]

Answer:

A and C

Explanation:

Helioseismology is a branch of science that makes use of  differential rotation and magnetic field to study he structure of the sun.

A filtergram represents the photo of the surface of the sun that is made using high energy particles being accelerated by the sun's magnetic field. <em>Hence, it can only be used to study the surface and not the layers below the photosphere.</em>

The chromosphere of the sun has a temperature between 6,000 °C to about 20,000°C while the photosphere has a temperature between 4,230 and 5,730 °C.<em> Hence, the chromosphere has a higher temperature.</em>

The only true options are A and C.

The moon Umbriel orbits Uranus (mass = 8.68 x 10^25 kg) at a distance of 2.66 x 10^8 m. What is Umbriel's orbital period (in hou
Whitepunk [10]

Answer:

T = 99.51 hour

Explanation:

Mass of Uranus, M=8.68\times 10^{25}\ kg

The moon Umbriel orbits Uranus at a distance of 2.66\times 10^8\ m

We need to find Umbriel's orbital period. Let it is T. Using Kepler's third law of motion to find it.

T^2\propto r^3\\\\T^2=\dfrac{4\pi^2r^3}{GM}\\\\T^2=\dfrac{4\pi^2\times (2.66\times 10^8)^3}{6.67\times 10^{-11}\times 8.68\times 10^{25}}\\\\T=358244.51\ s

As 1 hour = 3600 s

358244.51 s = 99.51 hour

Hence, Umbriel's orbital period is 99.51 hour.
