So the air evaporate s and mix the temptures and marks air power to the same theme as the other the two degrees lower and lower until they are the same
Answer:
The bone is compressed to 4.213*10⁻⁶ m.
Explanation:
Given that ,
Mass of the person M = 85 kg,
Length of femur L =0.65 m
Radius of femur r = 0.02 m
To find,
Compression of the bone l = ?
The Young's Modulus is given by Y=
Young's modulus of human femur bone is Y = 9.4 *10⁹ Pa
Rearranging formula ,
l =
Weight supported by femur bone is 85 *0.9 =76.5 Kg
Area = π r² =3.14* (0.02)² = 0.001256 m
The length of compressed bone is
l = = =4213.89 *10⁻⁹
l = 4.213*10⁻⁶ m
The bone is compressed to 4.213*10⁻⁶ m.
From the definition of average velocity,
,
and the fact that constant acceleration means
we can solve for the time :
Answer:
Part a)
acceleration = -0.042 m/s/s
Part b)
initial speed = 14.17 m/s
final speed = 5.77 m/s
Explanation:
Part a)
Let the initial velocity of the motorcycle is
now at the end of 80 s let the speed is
after another 120 s let the speed will be
now we know that
also we know that
also we have
now we can say
also we know
Part b)
now we have
so the starting velocity of the trip is
now speed after t = 200 s is given as
<span>436 km
The conversion factor between kilocalorie/hour and watts is 1.163 (1 kcal/hr = 1.163 watt). So let's convert the energy consumption of the bird from watts to kcal/hr
3.7 w / 1.163 w hr/kcal = 3.18 kcal /hr
1 gram of fat has 9 kcal, so the total number of kcals consumed will be 4 * 9 = 36.
So the bird can fly for 36/3.18 = 11.32 hours
The distance traveled will be
11.32 h * 3600 s/h * 10.7 m/s / 1000 m/km = 436 km</span>
