ANSWER ALL THREE QUESTIONS AND ILL GIVE U BRAINLIEST PLS AND THANK Uuu (i’m struggling if u can’t tell.) A radio signal travels at 4.00 x 10' meters per second. How many seconds will it take
for a radio signal to travel from a satellite to the surface of Earth if the satellite is
orbiting at a height of 2.1 x 10 meters? Show your work. (Hint: d = it, where d is
distance, r is rate, and 1 is time.)

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

answer: it is d

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
