Answer:
Water is essential for all living things. Water's unique density, high specific heat, cohesion, adhesion, and solvent abilities allow it to support life.
Answer:
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
Explanation:
Diameter = 135 m
Radius, r = 0.5 x 135 = 67.5 m
It revolves at a constant rate and takes 30 minutes
Period, T = 30 minutes= 1800 s

Linear velocity, v = radius x angular velocity
v = 67.5 x 3.98 x 10⁻³ = 0.2355 m/s
Linear velocity of a rider in a capsule that is located at the perimeter of the wheel = 0.2355 m/s
That symbol represents a source of DC, usually a battery.
The zig-zag line represents a resistor, and the two little circles
connected by a short line represent a switch in the closed position.,
