Answer:
17867.36 Pa
Explanation:
height, h = 1.72 m
density of blood, d = 1.06 x 10^3 kg/m^3
acceleration due to gravity, g = 9.8 m/s^2
Pressure P = h x d x g
P = 1.72 x 1.06 x 1000 x 9.8
P = 17867.36 Pa
Answer:
Gradient of the hill is 53.33m/km which is lesser than the 500 m/km. So, he will be able to climb the hill conveniently.
Explanation: Given that
Maximum gradient = 500 m/km
Total distance = 1.5 km
Starting elevation = 20 m
Final elevation = 100 m
Gradient = change in elevation/ total distance.
Now, substitute the values into the formula.
Gradient = (100m - 20m)/1.5km
= 80m/1.5km
= 53.33m/km
Gradient of the hill is 53.33m/km which is lesser than the 500 m/km. So, he will be able to climb the hill conveniently.
