When you illustrate the problem description, the direction of distance travelled is shown in the picture. But actually, since you are asked of the average velocity, you really don't need the drawing. It is given that the constant speed is 55 km/h. Since distance is speed multiplied with time, then you only have to multiply the constant speed and the respective time so you can find the distance. The average velocity, on the other hand, is the total distance per total time travelled. So since there is a constant speed, all the terms for time will be cancelled. Therefore, the average velocity is the constant speed. But we have to add the direction, which is south so it will denote a negative sign. The final answer for average velocity is -55 km/h.
Answer:
temperature for which two scales are same is given as
Explanation:
As we know that temperature scales are linear function
so we can compare two temperature scales by
now we have
here we know that
so we have

Answer:
9693.90616 m
Explanation:
= Atmospheric pressure = 101325 Pa
g = Acceleration due to gravity = 9.81 m/s²
= Density of seawater = 1025 kg/m³
The pressure is
Pressure is given by
The depth in seawater would be 9693.90616 m
