Answer:
Our solar system has total eight planets out of which four are inner planets and four are outer planets. The four outer planets are Jupiter, Saturn, Uranus and Neptune. The common characteristics of outer planets is that they are gaseous planets. They are larger on size than the inner rocky planets and are faraway from Sun. They have larger period of revolution around the Sun.
Uranus is a gaseous planet and lies far from Sun and hence has large period of revolution. It takes 84 Earth years to revolve around Sun. This data indicates that Uranus resides in the outer region of the Solar System.
Answer:
υ = 345.82 m/s
Explanation:
The formula used to find the speed of sound in air, at different temperatures is given as follows:
where,
υ = speed of sound at given temperature = ?
υ₀ = speed of sound at 0°C = 331 m/s
T = temperature in K = 15°C + 273 = 298 k
Therefore, using these values in the equation, we get:
<u>υ = 345.82 m/s</u>
<span>Answer: 110.12 m/s </span>
We will use the formula A1V1 = A2V2
where 7.8 m/s is divided with 0.0085 m then multiply to 0.12 m, the result will
be 110.117 or 110.12 m/s. This is related to the continuity of fluid flow in
which as liquid moves horizontally, the same amount of liquid goes out as it comes in or the
liquid itself do not change as it moves but the speed does when the diameter changes.
Explanation:
The scanner records the time from when a ultrasound wave is emitted to when its reflection is received. A technician calculates the depth of the reflection using the equation as :
The distance covered by ultrasonic wave when it was emitted and gets reflected is 2d. Speed is given by :
d is distance and t is time
Here, d = 2d
So, the factor of (1/2) is used because the distance covered by the wave is 2 times when it was emitted and received.
