Answer:
Venus
Explanation:
The terrestrial planets are the planets in the solar system which are closer to the Sun, compared to the Gaseous giants like Jupiter.
Venus is the planet that is near the Sun and is formed where the solar system's temperatures are very high.
Mercury is the planet which has a very thin atmosphere and so is very cold. Venus is a planet similar to Earth, but it has a dense atmosphere . So venus is hottest compared to other planets.
length × width × height
20 cm × 10 cm × 5 cm = 1,000 cm
Answer:
The frequency heard by the motorist is 4313.2 Hz.
Explanation:
let f1 be the frequency emited by the police car and f2 be the frequency heard by the motorist, let v1 be the speed of the police car and v2 be the speed of the motorist and v = 343 m/s be the speed of sound.
because the police car is moving towards the motorist at a higher speed, then the motorist will hear a increasing frequency and according to Dopper effect, that frequency is given by:
f1 = [(v + v2/(v - v1))]×(f2)
= [( 343 + 30)/(343 - 36)]×(3550)
= 4313.2 Hz
Therefore, the frequency heard by the motorist is 4313.2 Hz.
