Answer: Oil )Explanation:
Here Oil is the most viscous liquid.
The liquid with the most intermolecular force is high viscous. viscosity is how smoothly a liquid flows and how hardly the liquid flows it is highly viscous.
Answer:
a) 11.21 m/s
b) 513.89 N
Explanation:
mass of addict = 77 kg
radius of circle= 10 m
velocity of circular motion v =5.6 m/s
a)time period of motion
T= 2πr/v = 2×3.14×10/5.6 = 11.21 sec
b) At the highest point normal reaction force F_N is upward
the gravitational force F_g is downward and centripedal force mv^2/r is upward
F_N= F_g - mv^2/r
= 77*9.81- 77*5.6^2/10
= 513.89 N
Horizontal component = V cos(30°) = V (√3/2) = 73.2 m/s
Vertical component = V sin(30°) = V (0.5) = 100 m/s
In 6 seconds, the object travels horizontally (173.2 m/s x 6 sec) = 1,039 m
After 6 seconds, the object's height above the ground is
H = V₀t + 1/2 a t²
H = (100 m/s)(6 s) + (1/2) (-9.8 m/s²) (6 s)²
H = (600 m) - (4.9 m/s²) (36 s²)
H = (600 m) - (176.4 m)
Height = 423.6 m
