Answer:
Part a)
Part b)
Explanation:
As per momentum conservation we know that there is no external force on this system so initial and final momentum must be same
So we will have
Part b)
By equation of kinetic energy we have
Answer:
The pressure exerted by camel feet is <u>2000 N/m²</u>.
Step-by-step explanation:
<h3><u>Solution</u> :</h3>
Here, we have given that ;
- Force applied on camel feet = 4000 N
- Total area of camel feet = 2 m²
We need to find the pressure exerted by camel feet.
As we know that :
Substituting all the given values in the formula to find the pressure exerted by camel feet.
Hence, the pressure exerted by camel feet is 2000 N/m².
To solve this problem we will apply the concept of wavelength, which warns that this is equivalent to the relationship between the speed of the air (in this case in through the air) and the frequency of that wave. The air is in standard conditions so we have the relation,
Frequency
Speed of sound in air
The definition of wavelength is,
Here,
v = Velocity
f = Frequency
Replacing,
Therefore the wavelength of that tone in air at standard conditions is 0.589m
Velocity means [ (speed) and (direction) ].
If you're traveling around a curve, then your direction is
always changing. So your velocity is always changing,
even if your speed isn't.
The formula for average speed is S=D/T
1. S=72m/37s
Divide
S= 1.94
Kira's average speed is 1.94m/s.
2. S=7.5km / 1.5h
S=5
Your average speed is 5km/h
3. S=1260km/3.5h
S=360
The airplanes average speed is 360km/h
