Answer: The earth is comprised of silicate materials as well as metals. The amount of gas is less here because of its location near to the sun. Due to its relative high surface temperature, the gases such as hydrogen and helium gets evaporated and disappears.
Whereas the sun is entirely comprised of hydrogen and helium gas, of which hydrogen is the dominant one. It has an extremely high temperature of about 5500°C.
Any one trial might have been done incorrectly.
Answer:
Explanation:
a ) Temperature at ground level is a field and it is scalar field .At any point in space near ground level , the temperature is specific so it is a field . It is scalar because temperature has no direction .
b )
Wind velocity at 100 feet above the ground is also a field but it is a vector field . At any point in space , the wind velocity is specific so it is a field . It is vector because velocity has a particular direction at any point .
c )
Gravitational force on Roessler Hall is a vector field because gravitational force also depends on location in space and it has direction.
d )
Height of a person in your group is not a space because it does not depend upon location is space . It is same for all location .
e )
Height (above sea level) of the ground is a field because it also depends upon location in space . It is scalar field .
f )
Slope of the surface of the earth is a scalar field .
The imaginary line from the tip of the football to the football to the sideline is called Line of Scrimmage. I believe.

Explanation:
This question is incomplete.
I'll answer this question on general terms. You'll get your result if you apply the steps I'll highlight below.
To start with; what's Ampere law;
It states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.
The simple translation of this law is that, the sum of current in the close loop gives us the desired result.
Rephrasing your question;
Three currents, (I1 = +3A, I2 = +4A and I3 = -5A) are passing through a surface bounded by a closed path. The currents have different values and directions. According to Ampere’s law, what is the value of I on the right side of this equation?
First, we take note of the signs in front of the given currents.
The negative sign in front of I3 means that; it is moving in opposite direction of I1 and I2.
To calculate the value of I.
The value of I is the sum of the three currents:
i.e. 3A + 4A - 5A
I = 2 A
