Answer:

Average speed = 0.35 m/s

Explanation:

Given the following data;

Distance = 1.3 Km

Time = 62 minutes

To find the average speed in m/s;

First of all, we would convert the quantities to their standard unit (S.I) of measurement;

Conversion:

1.3 kilometres to meters = 1.3 * 1000 = 1300 meters

For time;

1 minute = 60 seconds

62 minutes = X

Cross-multiplying, we have;

X = 62 * 60

X = 3720 seconds

Now, we can calculate the average speed in m/s using the formula;

Speed = \frac {distance}{time}

Speed = \frac {1300}{3720}

Average speed = 0.35 m/s

Answer:

To get to the moon you need to travel in a spacecraft and will take approximately 10 hours of travel.

Explanation:

Since the first spaceship to land on the moon in 1959 , several trips have been made so far.The NASA trip in 2006 opened more routes to the moon and achieved a time travel of 8 hours compared to the first one done in 1959 that was 34 hours of time travel.Currently, NASA has intiated programs that will see robots sent to the moon for research.

Hope this helps!

Despite their extensive applications in communication systems, radio waves a not the only form of EM waves present in our atmosp
tiny-mole [99]

Let us assume that the definition of frequency, wavelength and wave speed is determined by the function

f = \frac{v}{\lambda}

Here,

v = Velocity of wave

\lambda = Wavelength

f = Frequency

We know that the earth has the ability to absorb visible light but that it can also emit a longer radiation wavelength. This assessment allows us to confirm that option A. Is correct. In turn, if said wavelength is large, being inversely proportional to the frequency,

\lambda \propto \frac{1}{f}

This does tend to be lower radiation. The correct options are:

A.The earth absorbs visible light and emits radiation with a longer wavelength.

B.The earth absorbs visible light and emits radiation with a lower frequency.
