Distance = rate * time
d = (20.0 mph)(0.500 hr) + (40.0 mph)(1.00 hr) + (30.0 mph)(0.500 hr) + (50.0 mph)(2.00 hr)
d = 10.0 miles + 40.0 miles + 15.0 miles + 100. miles
d = 165 miles
Evaporation is the process of the hydrological cycle maintained by the ocean's large surface area.
The value of the spring constant of the spring is 14.7 N/m.
The given parameters;
- <em>mass attached to the spring, m = 30 g</em>
- <em>length of the spring, L₀ = 10 cm</em>
- <em>angular speed of the mass = 90 rpm</em>
- <em>final length of the spring, L₁ = 12 cm</em>
The extension of the spring is calculated as follows;
The value of the spring constant of the spring is calculated by applying Hooke's law;
