Answer:
0º - 23.5º - 45º - 90º
Explanation:
The inclination angle of the Earth's axis with respect to its orbit around the Sun, determines that the duration enters the day and the night is different.
If it is not inclined (angle 0º) the two and niches have the same hardness
If the angle were very high (about 90º) the night would be very long, about half of the orbit period about six months.
Based on this presentation we can answer the question
The Sumo exposition from highest to lowest is
0º - 23.5º - 45º - 90º
The statement that best describes electrons is that t<span>hey are negative subatomic particles and are found surrounding the nucleus.</span>
Bigger change in velocity because the object is lighter than the object with more mass so it would move further (sorry it’s not a great explanation)
Answer:
C
Explanation:
Power is work divided by time:
P = W / t
Work is force times distance:
W = F d
Therefore:
P = F d / t
Given that F = 500 N, d = 60 m, and t = 240 s:
P = 500 N * 60 m / 240 s
P = 125 W
Answer is C.
Answer:
The speed of the bat is 5.02 m/s.
Explanation:
Given that,
Frequency = 30.0 kHz
Frequency of echo = 900 Hz
We need to calculate the frequency
Using formula of beat frequency
Put the value into the formula
We need to calculate the speed of the bat
Using Doppler equation
Put the value into the formula
Hence, The speed of the bat is 5.02 m/s.
