Answer:
the pressure at the depth is 1.08 × Pa
Explanation:
The pressure at the depth is given by,
P = h g
Where, P = pressure at the depth
h = depth of the Pacific Ocean in the Mariana Trench = 36,198 ft = 11033.15 meter
= density of water = 1000
g = acceleration due to gravity ≈ 9.8
P = 11033.15 × 9.8 × 1000
P = 1.08 × Pa
Thus, the pressure at the depth is 1.08 × Pa
Answer:
Explanation:
It is given that,
Angular speed of the football spiral,
Radius of a pro football, r = 8.5 cm = 0.085 m
The velocity is given by :
v = 3.68 m/s
The centripetal acceleration is given by :
So, the centripetal acceleration of the laces on the football is . Hence, this is the required solution.
