Answer:

Cosmic Microwave Background

Explanation:

The cosmic background radiation gives us a glimpse into the formative years of our universe. The cosmic background radiation contains radiation from the epoch of recombination of the Big Bang. The radiation is most visible in the microwave region of the electromagnetic spectrum. The radiation poses a strong case that the universe originated from the big bang.

if the current is 0.4 A for the 20 ohm resistor, what is the value for the potential difference? ii) Would it be different for t

Genrish500 [490]

Answer:potential difference is more or less like voltage. Using ohms, V=IR

Where V is Voltage

I is Current =0.4A

R is Resistance=20ohms

V=0.4*20

V=8V

Hence the potential difference will be 8V.

ii) V=0.4*30

V=12V

Explanation:

The voltage of potential difference is directly proportional to the current and the resistance. So if one increase or decrease, it will have impact on the other.

From the calculations, when the resistance increase, the voltage will increase to appreciate the change.

In physics, why would an equation like y=mx+b be plotted as a straight line rather than as a parabola, as is done in math?

notka56 [123]

Answer:

Explanation:

In Both Physics and Math

y=mx+b is plotted as straight line where

m=slope of line

b=intercept on Y-axis

whereas Equation of parabola is something like this

$y^2=4ax$

$x^2=4ay$

Math is a tool to solve Physics problems so equations are same in math and physics
