Answer:
C. g/cm³
Explanation:
The slope is measured by calculating the variation of the Y values over the X values between two points on a line.
So, the formula is: Slope = Δy/Δx
That means that we also take the units.
In this case, the Y-axis unit is in g, while the X-axis unit is in cm³.
Dividing a Y-variation over an X-variation will give you g/cm³.
In this case, let's assume the line passes through (10,100) (not exactly, but close enough for the example), and it passes through (0,0)
So the slope would be: (100-0) g / (10-0) cm³ = 10 g/cm³
Answer:
Volts/Meter
Newtons/Coulomb
Explanation:
Volts/ Meter and Newtons/Coulomb both are same and the units of Electric field intensity or electric field strength.
Electric field strength E is the force per unit charge. It is measured in Newton/Coulomb in SI unit. It is a vector quantity directed in the direction of force.
Mathematically,
Electric field strength = Force/Charge
E = F / q₀
= Newton / Coulomb = NC⁻¹ 1
We know that
Newton = Joule/meter 2
Also
Volt = Joule/Coulomb 3
So put 3 in 2 we get
Newton = (Volt Coulomb)/meter put in 1
E = (Volt Coulomb)/(meter Coulomb)
= Volt / meter
Hence
Newton / Coulomb = Volt / meter
Answer:
A mercury barometer has a glass tube that is closed at the top and open at the bottom.At the bottom of the tube is a pool of mercury.The mercury sits in a circular,shallow dish surrounding the tube.The mercury in the tube will adjust itself to match the atmospheric pressure above the dish.

Answer:
n = 1,429
Explanation:
In this exercise you are asked to calculate the refractive index, it is a constant that depends on the wavelength and relates the behavior of light when passing through two different material media.
The refractive index of a material is given by
n = c / v
where n is the refractive index, c the speed of light and v the speed in the material medium
let's calculate
n = 3.0 108 / 2.1 108
n = 1,429
The correct answer for this question would be D) Global warming or the fourth option.
