Answer:
The torque will be felt by the coil is zero
Explanation:
The torque is:
Where
μ is the magnetic moment = N * I * A, where N is the number of turns, I is the current and A is the area
A = 0.1 cm² = 1x10⁻⁵m²
If the angle between the area and the magnetic field is 0 (are in parallel), then:
Answer:
The possible quantum numbers for Ca atom when it is in excited
n = 4
l= 1
m =-1,0,1
Explanation:
Given that,
Atomic number = 20
The configuration of Ca
So, The principle quantum number is n =4.
The azimuthal quantum number can take value from 0,1,2...(n-1)
In the ground state, l= 0
When it is excited to p state
Then, l = 1
The magnetic quantum number can take value from l to -l
Hence, The possible quantum numbers for Ca atom when it is in excited
n = 4
l= 1
m =-1,0,1
True
Mars' atmosphere is over 100 times thinner than Earth's and is primarily composed of carbon dioxide, nitrogen and argon gases. Oxygized dust particles kicked up from the Martian surface fill the atmosphere turning Mars' skies a rusty tan color, according to NASA(opens in new tab).
Water exists on Mars but the atmosphere is too thin for it to last long on the surface in a liquid state. Instead, water on Mars is found below the surface of the polar regions as water-ice and also as seasonal briny water flows down hillsides and crater walls.
Despite Mars' thin atmosphere, the Red Planet still exhibits a dynamic climate and extreme weather events including impressive dust storms and even snow! But Mars hasn't always been this way. NASA's MAVEN mission scientists reported that Mars once had a thick atmosphere(opens in new tab) that could have supported surface liquid water on the surface for extended periods of time.
What is mars?
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere, and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes, and polar ice caps. It has two small and irregularly shaped moons: Phobos and Deimos.

The correct answer to the question is B) 5,700 years.
EXPLANATION:
Before going to answer this question, first we have to understand half life period of a radio active substance.
The half life period ![[\ T_{1/2}\ ]](https://tex.z-dn.net/?f=%5B%5C%20T_%7B1%2F2%7D%5C%20%5D)
of a radio active substance is defined as the time in which half of the radio active specimen has undergone decay.
As per the question, the initial concentration of the radioactive carbon-14 is given as 10,000.
Hence, initial concentration 
.
After 5,700 years, the remaining radio active specimen is 5000. It means that half of the radio active specimen has undergone decay in 5,700 years.
Hence, half life period of the radio active carbon-14 specimen is 5,700 years.
