<em>A bicycle and rideer travel along a road. the true about the sentence is: a. the bicycle and the rider undergo translation. The rider moving because you have to push the pedals and make the bike moves too.</em>
The time must be measured with respect to gravity. As it falls, it has free fall that is the force acting on it will be the gravity.With the distance in account, d = 1/2 gt²
t = √(2d/g)
Given:
ρ = 1.18 kg/m³, density of air
v = 8 m/s, flow velocity
Q = 9 m³/s, volumetric flow rate
The minimum power required (at 100% efficiency) is

The actual power will be higher because 100% efficiency is not possible.
Answer: 339.8 W (nearest tenth)
Since the density of water is 1g/cm^3, The mass of water needed to fill the tank is 150000 grams
A spring is an object that can be deformed by a force and then return to its original shape after the force is removed.Springs come in a huge variety of different forms, but the simple metal coil spring is probably the most familiar. Springs are an essential part of almost all moderately complex mechanical devices; from ball-point pens to racing car engines.
