Answer:

6.39 meters

Explanation:

t=sqrt(2d/g)

convert cm to m...... t=sqrt(2*0.73/9.81)...... t=0.1488 seconds

v=d/t...... v=0.70/0.1488....... v=4.7m/s

Now, the new time out the window is t=sqrt(2*6.68/9.81)..... t=1.36 seconds

d=vt....... d=(4.7)*(1.36)...... d=6.39 meters!

Why is creativity important in constructing scientific questions?
jeka94
The answer is B. The obvious questions do not always lead to interesting results. This is because if everyone did the same thing every time, we wouldn't find any new data. With variables, we have so many different options, leading to creativity and new data found!

An 800-kHz radio signal is detected at a point 2.7 km distant from a transmitter tower. The electric field amplitude of the sign
dimaraw [331]

Answer:

Option D is correct: 170 µW/m²

Explanation:

Given that,

Frequency f = 800kHz

Distance d = 2.7km = 2700m

Electric field Eo = 0.36V/m

Intensity of radio signal

The intensity of radial signal is given as

I = c•εo•Eo²/2

Where c is speed of light

c = 3×10^8m/s

εo = 8.85 × 10^-12 C²/Nm²

I = 3×10^8 × 8.85×10^-12 × 0.36²/2

I = 1.72 × 10^-4W/m²

I = 172 × 10^-6 W/m²

I = 172 µW/m²

Then, the intensity of the radio wave at that point is approximately 170 µW/m²
