If we check a table of certain stars , we will see the the Sun is an average sized star.
So, we can say that Our Sun is considered an average-sized star.
Answer:
AD
Explanation:
electromagnetic waves do not need a medium to travel, examples are ultraviolet radiation and infrared radiation.
20km every 1 hr is what 20km/hr means.
so 3hrs is 20km*3=60km.
Answer:
v=343m/s
Explanation:
We have to take into account the expressions
if we assume that 256Hz is the fundamental frequency we have
and for wavelength
hope this helps!!
Given the final velocity (Vf) and the acceleration (a), the distance that should be traveled by the plane is calculated through the equation,
d = (Vf² - Vi²) / 2a
V1 should be zero because the light plane started the motion from rest. Substituting the given values,
d = ((33 m/s)² - 0)) / 2(3 m/s²)
The distance is therefore equal to 181.5 meters.
